Quantum cryptography is arguably the fastest growing area in quantum information science.
Novel theoretical protocols are designed on a regular basis, security proofs are constantly …

Concerted efforts are underway to establish an infrastructure for a global quantum Internet to
realise a spectrum of quantum technologies. This will enable more precise sensors, secure …

We perform decoy-state quantum key distribution between a low-Earth-orbit satellite and
multiple ground stations located in **nglong, Nanshan, and Graz, which establish satellite-to …

The recent launch of the Micius quantum-enabled satellite heralds a major step forward for
long-range quantum communication. Using single-photon discrete-variable quantum states …

Optical quantum communication utilizing satellite platforms has the potential to extend the
reach of quantum key distribution (QKD) from terrestrial limits of∼ 200 km to global scales …

Satellite-based quantum terminals are a feasible way to extend the reach of quantum
communication protocols such as quantum key distribution (QKD) to the global scale. To that …

The measurement of quantum signals that travel through long distances is fundamentally
and technologically interesting. We present quantum-limited coherent measurements of …

In this paper, we present a novel analysis of the feasibility of quantum key distribution
between a LEO satellite and a ground station. First of all, we study signal propagation …

Physical theories are developed to describe phenomena in particular regimes, and
generally are valid only within a limited range of scales. For example, general relativity …

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 …
