Breaking the Rate-Loss Bound of Quantum Key Distribution with Asynchronous Two-Photon Interference [PDF]
PRX Quantum, 2021 Twin-field quantum key distribution can overcome the secret key capacity of repeaterless quantum key distribution via single-photon interference. However, to compensate for the channel fluctuations and lock the laser fluctuations, the techniques of phase ...

Ruling out Higher-Order Interference from Purity Principles
Entropy, 2017 As first noted by Rafael Sorkin, there is a limit to quantum interference. The interference pattern formed in a multi-slit experiment is a function of the interference patterns formed between pairs of slits; there are no genuinely new features resulting ...

Quantum interference of topological states of light [PDF]
Science Advances, 2018 Quantum interference of topologically protected single-photon states is demonstrated in an integrated photonic chip. Topological insulators are materials that have a gapped bulk energy spectrum but contain protected in-gap states appearing at their ...

Generalised phase kick-back: the structure of computational algorithms from physical principles
New Journal of Physics, 2016 The advent of quantum computing has challenged classical conceptions of which problems are efficiently solvable in our physical world. This motivates the general study of how physical principles bound computational power.
