Quantum key distribution (QKD) is a family of protocols for growing a private encryption key
between two parties. Despite much progress, all ground-based QKD approaches have a …

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 …

How to remove detector side channel attacks has been a notoriously hard problem in
quantum cryptography. Here, we propose a simple solution to this problem—measurement …

Noise can be considered the natural enemy of quantum information. An often implied benefit
of high-dimensional entanglement is its increased resilience to noise. However, manifesting …

The quantum internet is predicted to be the next-generation information processing platform,
promising secure communication, and an exponential speed-up in distributed computation …

Quantum key distribution,(QKD) is the first commercial application in the new field of
quantum information, with first routine applications in government and financial sectors and …

In this Letter, we present a cosmic Bell experiment with polarization-entangled photons, in
which measurement settings were determined based on real-time measurements of the …

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 …

We report the distribution of time-bin entangled photon pairs over 300 km of optical fiber. We
realized this by using a high-speed and high signal-to-noise ratio entanglement …

Bell's theorem states that some predictions of quantum mechanics cannot be reproduced by
a local-realist theory. That conflict is expressed by Bell's inequality, which is usually derived …
