Space Applications of Quantum Technology

Edited by: Rainer Kaltenbaek, Rupert Ursin and Markus Aspelmeyer

Space-based tests of fundamental physics have a long history, from early tests of general relativity to more recent missions such as gravity probe B and proposed missions to test the equivalence principle (STE-QUEST) and gravitational decoherence (MAQRO). These more recent proposals make extensive use of quantum technologies, from atomic clocks to weak force sensors. Deploying any technology into space pushes specifications to the limit and this will be especially true for quantum-enabled technologies. Recent advances in space technology as developed for experiments such as LISA and LISA Pathfinder have allowed researchers to optimally harness the space environment for quantum experiments.

This thematic series is dedicated to all aspects of space-based quantum technologies from fundamental physics to quantum communication protocols including proposals for new space-based quantum experiments as well as terrestrial experimental tests of new quantum technologies for space deployment.

    Laser annealing heals radiation damage in avalanche photodiodes

    Avalanche photodiodes (APDs) are a practical option for space-based quantum communications requiring single-photon detection. However, radiation damage to APDs significantly increases their dark count rates an...

    Mitigating radiation damage of single photon detectors for space applications

    Single-photon detectors in space must retain useful performance characteristics despite being bombarded with sub-atomic particles. Mitigating the effects of this space radiation is vital to enabling new space ...

    CubeSat quantum communications mission

    Quantum communication is a prime space technology application and offers near-term possibilities for long-distance quantum key distribution (QKD) and experimental tests of quantum entanglement. However, there ...

    A blueprint for a simultaneous test of quantum mechanics and general relativity in a space-based quantum optics experiment

    In this paper we propose an experiment designed to observe a general-relativistic effect on single photon interference. The experiment consists of a folded Mach-Zehnder interferometer, with the arms distribute...

    Nanosatellite experiments to enable future space-based QKD missions

    We present a programme for establishing the space worthiness of highly-miniaturised, polarisation-entangled, photon pair sources using CubeSat nanosatellites. Once demonstrated, the photon pair sources can be ...

    Thermal noise in BEC-phononic gravitational wave detectors

    Quasiparticles in a Bose-Einstein condensate are sensitive to space-time distortions. Gravitational waves can induce transformations on the state of phonons that can be observed through quantum state discrimin...

    Macroscopic Quantum Resonators (MAQRO): 2015 update

    Do the laws of quantum physics still hold for macroscopic objects - this is at the heart of Schrödinger’s cat paradox - or do gravitation or yet unknown effects set a limit for massive particles? What is the f...
