Quantum Cryptography Beyond Quantum Key Distribution

Anne Broadbent, Christian Schaffner

Quantum cryptography is the art and science of exploiting quantum mechanical effects in order to perform cryptographic tasks. While the most well-known example of this discipline i…

Complete Generalized Gibbs Ensemble in an interacting Theory

Enej Ilievski, Jacopo De Nardis, Bram Wouters +3

In integrable many-particle systems, it is widely believed that the stationary state reached at late times after a quantum quench can be described by a generalized Gibbs ensemble (…

Modified atomic decay rate near absorptive scatterers at finite temperature

L. G. Suttorp, A. J. van Wonderen

The change in the decay rate of an excited atom that is brought about by extinction and thermal-radiation effects in a nearby dielectric medium is determined from a quantummechanic…

A self-interfering clock as a "which path" witness

Yair Margalit, Zhifan Zhou, Shimon Machluf +3

We experimentally demonstrate a new interferometry paradigm: a self-interfering clock. We split a clock into two spatially separated wave packets, and observe an interference patte…

Quantum theory of light scattering in a one-dimensional channel: Interaction effect on photon statistics and entanglement entropy

Mikhail Pletyukhov, Vladimir Gritsev

We provide a complete and exact quantum description of coherent light scattering in a one-dimensional multi-mode transmission line coupled to a two-level emitter. Using recently de…

How the Weak Variance of Momentum Can Turn Out to be Negative

M. R. Feyereisen

Weak values are average quantities,therefore investigating their associated variance is crucial in understanding their place in quantum mechanics. We develop the concept of a posit…
