Experimental implementation of bit commitment in the noisy-storage model.
TLDR
This work experimentally executed a bit commitment protocol that is secure as long as the attacker's quantum memory device is imperfect, and provides a general analysis of this protocol for a range of experimental parameters. Expand
Nanobob: a CubeSat mission concept for quantum communication experiments in an uplink configuration
We present a ground-to-space quantum key distribution (QKD) mission concept and the accompanying feasibility study for the development of the associated low earth orbit nanosatellite payload. TheExpand
A trusted node–free eight-user metropolitan quantum communication network
TLDR
This work presents a fully connected quantum communication network on a city-wide scale without active switching or trusted nodes, and demonstrates simultaneous and secure connections between all 28 pairings of eight users. Expand
Demonstrating an absolute quantum advantage in direct absorption measurement
TLDR
This work experimentally demonstrates an instance of an absolute advantage per photon probe that is exposed to the absorbative sample for optical direct absorption measurement, and enables improvement in the precision of measurement, per photon Probe, beyond what is achievable with an ideal coherent state.

Q3Sat: quantum communications uplink to a 3U CubeSat—feasibility & design
TLDR
It is demonstrated how to leverage the latest advancements in nano-satellite body-pointing to show that the 4 kg CubeSat can generate a quantum-secure key, which has so far only been shown by a much larger 600 kg satellite mission. Expand
Comparative study of afterpulsing behavior and models in single photon counting avalanche photo diode detectors
TLDR
It is shown that different individual detectors - even if identical in type, make, brand, etc - behave according to fundamentally different mathematical models, and it is wrong to draw universal conclusions about the physical meaning behind these models. Expand
Space QUEST mission proposal: experimentally testing decoherence due to gravity
Models of quantum systems on curved space-times lack sufficient experimental verification. Some speculative theories suggest that quantum correlations, such as entanglement, may exhibit differentExpand
Sub-Shot-Noise Transmission Measurement Enabled by Active Feed-Forward of Heralded Single Photons
Harnessing the unique properties of quantum mechanics offers the possibility of delivering alternative technologies that can fundamentally outperform their classical counterparts. These technologiesExpand
An Entanglement-Based Wavelength Multiplexed Quantum Communication Network
TLDR
This work presents a fully connected quantum network architecture in which a single entangled photon source distributes quantum states to a multitude of users and provides the potential for unprecedented quantum communication speeds. Expand
