The goal of quantum benchmarking is to certify that imperfect quantum communication devices (e.g., quantum channels, quantum memories, quantum key distribution systems) can still be used for meaningful quantum communication. However, the test states used in quantum benchmarking experiments may be imperfect as well. Many quantum benchmarks are only valid for states which match some ideal form, such as pure states or Gaussian states. We outline how to perform quantum benchmarking using arbitrary…

Test One to Test Many: A Unified Approach to Quantum Benchmarks.
It is shown that the average fidelity over all coherent states can be indirectly probed with a single setup, requiring only two-mode squeezing, a 50-50 beam splitter, and homodyne detection, and every quantum benchmark can be tested by preparing a single entangled state and measuring a single observable.
Schmidt-number benchmarks for continuous-variable quantum devices
We present quantum fidelity benchmarks for continuous-variable (CV) quantum devices to outperform quantum channels which can transmit at most $k$-dimensional coherences for positive integers $k$. We
Quantum benchmark via an uncertainty product of canonical variables.
An uncertainty-relation-type quantum benchmark for continuous-variable (CV) quantum channels that works with an input ensemble of Gaussian-distributed coherent states and homodyne measurements is presented that can verify the quantum-domain performance for all one-mode Gaussian channels.
A resource theory of quantum memories and their faithful verification with minimal assumptions
A complete set of game-theoretic conditions equivalent to the existence of a transformation from one quantum channel into another one, by means of classically correlated pre/post processing maps only, are provided, mirroring the resource theory of entanglement in quantum states.
Echo-Based Quantum Memory
In this book chapter we review photon echo based schemes for optical quantum memory. We outline the basic principles of the Atomic Frequency Comb (AFC), Gradient Echo Memory (GEM) and Rephased
Quantum-limited measurements of optical signals from a geostationary satellite
The results indicate that quantum communication is feasible in principle in such a scenario, highlighting the possibility of a global quantum key distribution network for secure communication.
Atmospheric continuous-variable quantum communication
We present a quantum communication experiment conducted over a point-to-point free-space link of 1.6 km in urban conditions. We study atmospheric influences on the capability of the link to act as a
Reliable entanglement verification
Any experiment attempting to verify the presence of entanglement in a physical system can only generate a finite amount of data. The statement that entanglement was present in the system can thus
Entanglement verification with detection-efficiency mismatch
Entanglement is a necessary condition for secure quantum key distribution (QKD). Here, we present a method to address the open problem of verifying entanglement when efficiency mismatch between
Clifford-group-restricted eavesdroppers in quantum key distribution
It is shown that for a large class of discrete variable protocols higher key rates are possible if the eavesdropper is restricted to a unitary operation from the Clifford group, and a secret key rate lower bound for BB84 is calculated.


On Circulant Matrices
Some mathematical topics, circulant matrices, in particular, are pure gems that cry out to be admired and studied with different techniques or perspectives in mind. Our work on this subject was
