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: "We introduce the framework of Bayesian relative belief that directly
evaluates whether or not the experimental data at hand support a given hypothesis
regarding a quantum system by directly comparing the prior and posterior probabilities
for the hypothesis. In model-dimension certification tasks, we show that the relative-belief
procedure typically chooses Hilbert spaces that are never smaller in dimension
than those selected from optimizing a broad class of information criteria, including
Akaike's criterion. As a concrete and focused exposition of this powerful evidence-based
technique, we apply the relative-belief procedure to an important application:
. In particular, just by comparing prior and posterior probabilities based on
data, we demonstrate its capability of tracking multiphoton emissions using (realistically
lossy) single-photon detectors in order to assess the actual quality of photon
sources without making assumptions, thereby reliably safeguarding source integrity
for general quantum-information and communication tasks with Bayesian reasoning.
Finally, we discuss how relative belief can be exploited to carry out parametric
model certification and estimate the total dimension of the quantum state for
the combined (measured) physical and interacting external systems described by
the Tavis-Cummings model.\r\n \r\n \r\n

text: The characterization of the complex spectral amplitude, that is, the
spectrum and spectral phase, of single-photon-level light fields is a crucial
capability for modern photonic quantum technologies. Since established pulse characterization
techniques are not applicable at low intensities, alternative approaches are required.
Here, we demonstrate the retrieval of the complex spectral amplitude of single-photon-level
light pulses through measuring their chronocyclic Q −function.
Our approach draws inspiration from quantum state tomography by exploiting the
analogy between quadrature phase space and time-frequency phase space. In the
experiment, we perform time-frequency projections with a quantum pulse gate (QPG),
which directly yield the chronocyclic Q −function.
We evaluate the complex spectral amplitude from the measured chronocyclic Q −function data with maximum likelihood estimation
(MLE), which is the established technique for quantum state tomography. The MLE
yields not only an unambigious estimate of the complex spectral amplitude of the
state under test that does not require any a priori
information, but also allows for, in principle, estimating the spectral-temporal
coherence properties of the state. Our method accurately recovers features such
as jumps in the spectral phase and is resistant against regions with zero spectral
intensity, which makes it immediately beneficial for classical pulse characterization
problems.

text: "Identifying a reasonably small Hilbert space that completely describes
an unknown quantum state is crucial for efficient quantum information processing.
We introduce a general dimension-certification protocol for both discrete and
continuous variables that is fully evidence based, relying solely on the experimental
data collected and no other unjustified assumptions whatsoever. Using the Bayesian
concept of relative belief, we take the effective dimension of the state as the
smallest one such that the posterior probability is larger than the prior, as
dictated by the data. The posterior probabilities associated with the relative-belief
ratios measure the strength of the evidence provide by these ratios so that we
can assess whether there is weak or strong evidence in favor or against a particular
dimension. Using experimental data from spectral-temporal and polarimetry measurements,
we demonstrate how to correctly assign Bayesian plausible error bars for the obtained
effective dimensions. This makes relative belief a conservative and easy-to-use
model-selection method for any experiment.\r\n \r\n

text: "The ability to apply user-chosen large-scale unitary operations with
high fidelity to a quantum state is key to realizing future photonic quantum technologies.
Here, we realize the implementation of programmable unitary operations on up to
64 frequency-bin modes. To benchmark the performance of our system, we probe different
quantum walk unitary operations, in particular, Grover walks on four-dimensional
hypercubes with similarities exceeding 95% and quantum walks with 400 steps on
circles and finite lines with similarities of 98%. Our results open a path toward
implementing high-quality unitary operations, which can form the basis for applications
in complex tasks, such as Gaussian boson sampling.\r\n \r\n

text: "Linear optical quantum networks, consisting of a quantum input state
and a multiport interferometer, are an important building block for many quantum
technological concepts, e.g., Gaussian boson sampling. Here, we propose the implementation
of such networks based on frequency conversion by utilizing a so-called multioutput
quantum pulse gate (MQPG). This approach allows the resource-efficient and therefore
scalable implementation of frequency-bin-based, fully programmable interferometers
in a single spatial and polarization mode. Quantum input states for this network
can be provided by utilizing the strong frequency entanglement of a type-0 parametric
down-conversion (PDC) source. Here, we develop a theoretical framework to describe
linear networks based on an MQPG and PDC and utilize it to investigate the limits
and scalabilty of our approach.\r\n \r\n \r\n

text: We demonstrate a high-dimensional mode-sorter for single photons based
on a multi-output quantum pulse gate, which we can program to switch between different
temporal-mode encodings including pulse modes, frequency bins, time bins, and
their superpositions. This device can facilitate practical realizations of quantum
information applications such as high-dimensional quantum key distribution and
thus enables secure communication with enhanced information capacity. We characterize
the mode-sorter through a detector tomography in 3 and 5 dimensions and find a
fidelity up to 0.958 ± 0.030 at the single-photon level.

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: "Broadband quantum light is a vital resource for quantum metrology
and spectroscopy applications such as quantum optical coherence tomography or
entangled two photon absorption. For entangled two photon absorption in particular,
very high photon flux combined with high time-frequency entanglement is crucial
for observing a signal. So far these conditions could be met by using high power
lasers driving degenerate, type 0 bulk-crystal spontaneous parametric down conversion
(SPDC) sources. This naturally limits the available wavelength ranges and precludes
deterministic splitting of the generated output photons. In this work we demonstrate
an integrated two-colour SPDC source utilising a group-velocity matched lithium
niobate waveguide, reaching both exceptional brightness 1.52⋅106pairssmWGHz
and large bandwidth (7.8 THz FWHM) while pumped with a few mW of continuous wave
(CW) laser light. By converting a narrow band pump to broadband pulses the created
photon pairs show correlation times of Δτ ≈ 120 fs
while maintaining the narrow bandwidth Δω\r\n
\ p\r\n ≪ 1 MHz of the CW pump light,
yielding strong time-frequency entanglement. Furthermore our process can be adapted
to a wide range of central wavelengths."

text: The latest applications in ultrafast quantum metrology require bright, broadband
bi-photon sources with one of the photons in the mid-infrared and the other in
the visible to near infrared. However, existing sources based on bulk crystals
are limited in brightness due to the short interaction length and only allow for
limited dispersion engineering. Here, we present an integrated PDC source based
on a Ti:LiNbO3 waveguide that generates broadband bi-photons with central wavelengths
at 860 nm and 2800 nm. Their spectral bandwidth exceeds 25 THz and is achieved
by simultaneous matching of the group velocities (GVs) and cancellation of GV
dispersion for the signal and idler field. We provide an intuitive understanding
of the process by studying our source’s behavior at different temperatures and
pump wavelengths, which agrees well with simulations.

text: Lithium niobate and lithium tantalate are among the most widespread
materials for nonlinear, integrated photonics. Mixed crystals with arbitrary Nb–Ta
ratios provide an additional degree of freedom to not only tune materials properties,
such as the birefringence but also leverage the advantages of the singular compounds,
for example, by combining the thermal stability of lithium tantalate with the
larger nonlinear or piezoelectric constants of lithium niobate. Periodic poling
allows to achieve phase-matching independent of waveguide geometry and is, therefore,
one of the commonly used methods in integrated nonlinear optics. For mixed crystals,
periodic poling has been challenging so far due to the lack of homogeneous, mono-domain
crystals, which severely inhibit domain growth and nucleation. In this work, we
investigate surface-near (<1μm depth) domain inversion on x-cut lithium
niobate tantalate mixed crystals via electric field poling and lithographically
structured electrodes. We find that naturally occurring head-to-head or tail-to-tail
domain walls in the as-grown crystal inhibit domain inversion at a larger scale.
However, periodic poling is possible if the gap size between the poling electrodes
is of the same order of magnitude or smaller than the average size of naturally
occurring domains. This work provides the basis for the nonlinear optical application
of lithium niobate tantalate mixed crystals.
