text: AbstractAn on-demand source of bright entangled
photon pairs is desirable for quantum key distribution (QKD) and quantum repeaters.
The leading candidate to generate such pairs is based on spontaneous parametric
down-conversion (SPDC) in non-linear crystals. However, its pair extraction efficiency
is limited to 0.1% when operating at near-unity fidelity due to multiphoton emission
at high brightness. Quantum dots in photonic nanostructures can in principle overcome
this limit, but the devices with high entanglement fidelity (99%) have low pair
extraction efficiency (0.01%). Here, we show a measured peak entanglement fidelity
of 97.5% ± 0.8% and pair extraction efficiency of 0.65% from an InAsP quantum
dot in an InP photonic nanowire waveguide. We show that the generated oscillating
two-photon Bell state can establish a secure key for peer-to-peer QKD. Using our
time-resolved QKD scheme alleviates the need to remove the quantum dot energy
splitting of the intermediate exciton states in the biexciton-exciton cascade.

text: We theoretically investigate strategies for the deterministic creation
of trains of time-bin entangled photons using an individual quantum emitter described
by a Λ-type electronic system. We explicitly demonstrate the theoretical generation
of linear cluster states with substantial numbers of entangled photonic qubits
in full microscopic numerical simulations. The underlying scheme is based on the
manipulation of ground state coherences through precise optical driving. One important
finding is that the most easily accessible quality metrics, the achievable rotation
fidelities, fall short in assessing the actual quantum correlations of the emitted
photons in the face of losses. To address this, we explicitly calculate stabilizer
generator expectation values as a superior gauge for the quantum properties of
the generated many-photon state. With widespread applicability in other emitter
and excitation–emission schemes also, our work lays the conceptual foundations
for an in-depth practical analysis of time-bin entanglement based on full numerical
simulations with predictive capabilities for realistic systems and setups, including
losses and imperfections. The specific results shown in the present work illustrate
that with controlled minimization of losses and realistic system parameters for
quantum-dot type systems, useful linear cluster states of significant lengths
can be generated in the calculations, discussing the possibility of scalability
for quantum information processing endeavors.

text: "Abstract\r\n Developing
coherent excitation methods for quantum emitters ensuring high brightness, optimal
single‐photon purity and indistinguishability of the emitted photons has been
a key challenge in the past years. While various methods have been proposed and
explored, they all have specific advantages and disadvantages. This study investigates
the dynamics of the recent swing‐up scheme as an excitation method for a two‐level
system and its performance in single‐photon generation. By applying two far red‐detuned
laser pulses, the two‐level system can be prepared in the excited state with near‐unity
fidelity. The successful operation and coherent character of this technique are
demonstrated using a semiconductor quantum dot (QD). Moreover, the multi‐dimensional
parameter space of the two laser pulses is explored to analyze its impact on excitation
fidelity. Finally, the performance of the scheme as an excitation method for generating
high‐quality single photons is analyzed. The swing‐up scheme itself proves effective,
exhibiting nearly perfect single‐photon purity, while the observed indistinguishability
in the studied sample is limited by the influence of the inevitable high excitation
powers on the semiconductor environment of the quantum dot."

text: Phonons in solid-state quantum emitters play a crucial role in their performance
as photon sources in quantum technology. For resonant driving, phonons dampen
the Rabi oscillations resulting in reduced preparation fidelities. The phonon
spectral density, which quantifies the strength of the carrier-phonon interaction,
is non-monotonous as a function of energy. As one of the most prominent consequences,
this leads to the reappearance of Rabi rotations for increasing pulse power, which
was theoretically predicted in Phys. Rev. Lett. 98, 227403 (2007). In this paper
we present the experimental demonstration of the reappearance of Rabi rotations.

text: On-chip emitters that can generate single and entangled photons are essential
building blocks for developing photonic quantum information processing technologies
in a scalable fashion. Semiconductor quantum dots (QDs) are attractive candidates
that emit high-quality quantum states of light on demand, however at a rate limited
by their spontaneous radiative lifetime. In this study, we utilize the Purcell
effect to demonstrate up to a 38-fold enhancement in the emission rate of InAs
QDs by coupling them to metal-clad GaAs nanopillars. These cavities, featuring
a sub-wavelength mode volume of 4.5x10-4 (λ/n)3 and low quality factor of 62,
enable Purcell-enhanced single-photon emission across a large bandwidth of 15
nm. The broadband nature of the cavity eliminates the need for implementing tuning
mechanisms typically required to achieve QD-cavity resonance, thus relaxing fabrication
constraints. Ultimately, this QD-cavity architecture represents a significant
stride towards developing solid-state quantum emitters generating near-ideal single-photon
states at GHz-level repetition rates.

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: "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.
