text: Superconducting nanowire single-photon detectors (SNSPDs) can enable
photon-number resolution (PNR) based on accurate measurements of the detector’s
response time to few-photon optical pulses. In this work, we investigate the impact
of the optical pulse shape and duration on the accuracy of this method. We find
that Gaussian temporal pulse shapes yield cleaner arrival-time histograms and,
thus, more accurate PNR, compared to bandpass-filtered pulses of equal bandwidth.
For low system jitter and an optical pulse duration comparable to the other jitter
contributions, photon numbers can be discriminated in our system with a commercial
SNSPD. At 60 ps optical pulse duration, photon-number discrimination is significantly
reduced. Furthermore, we highlight the importance of using the correct arrival-time
histogram model when analyzing photon-number assignment. Using exponentially modified
Gaussian distributions, instead of the commonly used Gaussian distributions, we
can more accurately determine photon-number misidentification probabilities. Finally,
we reconstruct the positive operator-valued measures of the detector, revealing
sharp features that indicate the intrinsic PNR capabilities.

text: Modulation conditioned on measurements on entangled photonic quantum
states is a cornerstone technology of optical quantum information processing.
Performing this task with low latency requires combining single-photon-level detectors
with both electronic logic processing and optical modulation in close proximity.
Here, we demonstrate low-latency feedforward using a quasi-photon-number-resolved
measurement on a quantum light source. Specifically, we use a multipixel superconducting
nanowire single-photon detector, amplifier, logic, and an integrated electro-optic
modulator in situ below 4 K. We modulate
the signal mode of a spontaneous parametric down-conversion source, conditional
on a photon-number measurement of the idler mode, with a total latency of (23±3)ns.
Furthermore, we investigate the resulting change in the photon statistics. This
represents an important benchmark for the fastest quantum photonic feedforward
experiments comprising measurement, amplification, logic, and modulation. This
has direct applications in quantum computing, communication, and simulation protocols.

text: 'By analyzing the physics of multi-photon absorption in superconducting
nanowire single-photon detectors (SNSPDs), we identify physical components of
jitter. From this, we formulate a quantitative physical model of the multi-photon
detector response that combines the local detection mechanism and local fluctuations
(hotspot formation and intrinsic jitter) with the thermoelectric dynamics of resistive
domains. Our model provides an excellent description of the arrival-time histogram
of a commercial SNSPD across several orders of magnitude, both in arrival-time
probability and across mean photon number. This is achieved with just three fitting
parameters: the scaling of the mean arrival time of voltage response pulses, as
well as the Gaussian and exponential jitter components. Our findings have important
implications for photon-number-resolving detector design, as well as applications
requiring low jitter, such as light detection and ranging (LIDAR).'

text: The titanium in-diffused lithium niobate waveguide platform is well-established
for reliable prototyping and packaging of many quantum photonic components at
room temperature. Nevertheless, compatibility with certain quantum light sources
and superconducting detectors requires operation under cryogenic conditions. We
characterize alterations in phase-matching and mode guiding of a non-degenerate
spontaneous parametric down-conversion process emitting around 1556 nm and 950 nm,
under cryogenic conditions. Despite the effects of pyroelectricity and photorefraction,
the spectral properties match our theoretical model. Nevertheless, these effects
cause small but significant variations within and between cooling cycles. These
measurements provide a first benchmark against which other nonlinear photonic
integration platforms, such as thin-film lithium niobate, can be compared.

text: "We apply principal component analysis (PCA) to a set of electrical
output signals from a commercially available superconducting nanowire single-photon
detector (SNSPD) to investigate their photon-number-resolving capability. We find
that the rising edge as well as the amplitude of the electrical signal have the
most dependence on photon number. Accurately measuring the rising edge while simultaneously
measuring the voltage of the pulse amplitude maximizes the photon-number resolution
of SNSPDs. Using an optimal basis of principal components, we show unambiguous
discrimination between one- and two-photon events, as well as partial resolution
up to five photons. This expands the use case of SNSPDs to photon-counting experiments,
without the need of detector multiplexing architectures.\r\n \r\n

text: Cryogenic opto-electronic interconnects are gaining increasing interest
as a means to control and readout cryogenic electronic components. The challenge
is to achieve sufficient signal integrity with low heat load processing. In this
context, we demonstrate the opto-electronic bias and readout of a commercial four-pixel
superconducting nanowire single-photon detector array using a cryogenic photodiode
and laser. We show that this approach has a similar system detection efficiency
to a conventional bias. Furthermore, multi-pixel detection events are faithfully
converted between the optical and electrical domains, which allows reliable extraction
of amplitude multiplexed photon statistics. Our device has a latent heat load
of 2.6 mW, maintains a signal rise time of 3 ns, and operates in free-running
(self-resetting) mode at a repetition rate of 600 kHz. This demonstrates the potential
of high-bandwidth, low noise, and low heat load opto-electronic interconnects
for scalable cryogenic signal processing and transmission.

text: "Abstract\r\n Lithium niobate
has emerged as a promising platform for integrated quantum optics, enabling efficient
generation, manipulation, and detection of quantum states of light. However, integrating
single-photon detectors requires cryogenic operating temperatures, since the best
performing detectors are based on narrow superconducting wires. While previous
studies have demonstrated the operation of quantum light sources and electro-optic
modulators in LiNbO3 at cryogenic temperatures, the thermal
transition between room temperature and cryogenic conditions introduces additional
effects that can significantly influence device performance. In this paper, we
investigate the generation of pyroelectric charges and their impact on the optical
properties of lithium niobate waveguides when changing from room temperature to
25 K, and vice versa. We measure the generated pyroelectric charge flow and correlate
this with fast changes in the birefringence acquired through the Sénarmont-method.
Both electrical and optical influence of the pyroelectric effect occur predominantly
at temperatures above 100 K."

text: At large scales, quantum systems may become advantageous over their classical
counterparts at performing certain tasks. Developing tools to analyze these systems
at the relevant scales, in a manner consistent with quantum mechanics, is therefore
critical to benchmarking performance and characterizing their operation. While
classical computational approaches cannot perform like-for-like computations of
quantum systems beyond a certain scale, classical high-performance computing (HPC)
may nevertheless be useful for precisely these characterization and certification
tasks. By developing open-source customized algorithms using high-performance
computing, we perform quantum tomography on a megascale quantum photonic detector
covering a Hilbert space of 106. This requires finding 108 elements of the matrix
corresponding to the positive operator valued measure (POVM), the quantum description
of the detector, and is achieved in minutes of computation time. Moreover, by
exploiting the structure of the problem, we achieve highly efficient parallel
scaling, paving the way for quantum objects up to a system size of 1012 elements
to be reconstructed using this method. In general, this shows that a consistent
quantum mechanical description of quantum phenomena is applicable at everyday
scales. More concretely, this enables the reconstruction of large-scale quantum
sources, processes and detectors used in computation and sampling tasks, which
may be necessary to prove their nonclassical character or quantum computational
advantage.

text: Superconducting nanowire single-photon detectors (SNSPDs) have been
widely used to study the discrete nature of quantum states of light in the form
of photon-counting experiments. We show that SNSPDs can also be used to study
continuous variables of optical quantum states by performing homodyne detection
at a bandwidth of 400 kHz. By measuring the interference of a continuous-wave
field of a local oscillator with the field of the vacuum state using two SNSPDs,
we show that the variance of the difference in count rates is linearly proportional
to the photon flux of the local oscillator over almost five orders of magnitude.
The resulting shot-noise clearance of (46.0 ± 1.1) dB is the highest reported
clearance for a balanced optical homodyne detector, demonstrating their potential
for measuring highly squeezed states in the continuous-wave regime. In addition,
we measured a CMRR = 22.4 dB. From the joint click counting statistics, we also
measure the phase-dependent quadrature of a weak coherent state to demonstrate
our device’s functionality as a homodyne detector.

text: Quantum photonic processing via electro-optic components typically
requires electronic links across different operation environments, especially
when interfacing cryogenic components such as superconducting single photon detectors
with room-temperature control and readout electronics. However, readout and driving
electronics can introduce detrimental parasitic effects. Here we show an all-optical
control and readout of a superconducting nanowire single photon detector (SNSPD),
completely electrically decoupled from room temperature electronics. We provide
the operation power for the superconducting detector via a cryogenic photodiode,
and readout single photon detection signals via a cryogenic electro-optic modulator
in the same cryostat. This method opens the possibility for control and readout
of superconducting circuits, and feedforward for photonic quantum computing.

text: "Dispersion is present in every optical setup and is often an undesired effect,
especially in nonlinear-optical experiments where ultrashort laser pulses are
needed. Typically, bulky pulse compressors consisting of gratings or prisms are
used\r\nto address this issue by precompensating the dispersion of the optical
components. However, these devices are only able to compensate for a part of the
dispersion (second-order dispersion). Here, we present a compact pulse-shaping
device that uses plasmonic metasurfaces to apply an arbitrarily designed spectral
phase delay allowing for a full dispersion control. Furthermore, with specific
phase encodings, this device can be used to temporally reshape the incident laser
pulses into more complex pulse forms such as a double pulse. We verify the performance
of our device by using an SHG-FROG measurement setup together with a retrieval
algorithm to extract the dispersion that our device applies to an incident laser
pulse."

text: Superconducting nanowire single-photon detectors (SNSPDs) show near
unity efficiency, low dark count rate, and short recovery time. Combining these
characteristics with temporal control of SNSPDs broadens their applications as
in active de-latching for higher dynamic range counting or temporal filtering
for pump-probe spectroscopy or LiDAR. To that end, we demonstrate active gating
of an SNSPD with a minimum off-to-on rise time of 2.4 ns and a total gate length
of 5.0 ns. We show how the rise time depends on the inductance of the detector
in combination with the control electronics. The gate window is demonstrated to
be fully and freely, electrically tunable up to 500 ns at a repetition rate of
1.0 MHz, as well as ungated, free-running operation. Control electronics to generate
the gating are mounted on the 2.3 K stage of a closed-cycle sorption cryostat,
while the detector is operated on the cold stage at 0.8 K. We show that the efficiency
and timing jitter of the detector is not altered during the on-time of the gating
window. We exploit gated operation to demonstrate a method to increase in the
photon counting dynamic range by a factor 11.2, as well as temporal filtering
of a strong pump in an emulated pump-probe experiment.

text: Metasurfaces provide applications for a variety of flat elements and devices
due to the ability to modulate light with subwavelength structures. The working
principle meanwhile gives rise to the crucial problem and challenge to protect
the metasurface from dust or clean the unavoidable contaminants during daily usage.
Here, taking advantage of the intelligent bioinspired surfaces which exhibit self-cleaning
properties, a versatile dielectric metasurface benefiting from the obtained superhydrophilic
or quasi-superhydrophobic states is shown. The design is realized by embedding
the metasurface inside a large area of wettability supporting structures, which
is highly efficient in fabrication, and achieves both optical and wettability
functionality at the same time. The superhydrophilic state enables an enhanced
optical response with water, while the quasi-superhydrophobic state imparts the
fragile antennas an ability to self-clean dust contamination. Furthermore, the
metasurface can be easily switched and repeated between these two wettability
or functional states by appropriate treatments in a repeatable way, without degrading
the optical performance. The proposed design strategy will bring new opportunities
to smart metasurfaces with improved optical performance, versatility, and physical
stability.

text: "Abstract\r\n We demonstrate
the fabrication of micron-wide tungsten silicide superconducting nanowire single-photon
detectors on a silicon substrate using laser lithography. We show saturated internal
detection efficiencies with wire widths ranging from 0.59 µm
to 1.43 µm under illumination at 1550 nm. We demonstrate
both straight wires, as well as meandered structures. Single-photon sensitivity
is shown in devices up to 4 mm in length. Laser-lithographically written devices
allow for fast and easy structuring of large areas while maintaining a saturated
internal efficiency for wire widths around 1 µm."
