A quantum entropy production operator
Ge Bai, Francesco Buscemi, Valerio Scarani
We introduce a fully quantum notion of entropy production based on the non-commutative extension of the classical log-ratio between forward and reverse processes. Given a pair of q…
All three-angle variants of Tsirelson's precession protocol, and improved bounds for wedge integrals of Wigner functions
Lin Htoo Zaw, Valerio Scarani
Tsirelson's precession protocol is a nonclassicality witness that can be defined for both discrete and continuous variable systems. Its original version involves measuring a preces…
Certifying the quantumness of a nuclear spin qudit through its uniform precession
Arjen Vaartjes, Martin Nurizzo, Lin Htoo Zaw +16
Spin precession is a textbook example of dynamics of a quantum system that exactly mimics its classical counterpart. Here we challenge this view by certifying the quantumness of ex…
Quantum Bayes' rule and Petz transpose map from the minimum change principle
Ge Bai, Francesco Buscemi, Valerio Scarani
Bayes' rule, which is routinely used to update beliefs based on new evidence, can be derived from a principle of minimum change. This principle states that updated beliefs must be…
Emergence of Fluctuation Relations in UNO
Peter Sidajaya, Jovan Hsuen Khai Low, Clive Cenxin Aw +1
In the last two decades, fluctuation theorems have been proved formally and demonstrated experimentally for several variables (such as entropy production, work, or flux) and differ…
Even-parity precession protocol for detecting nonclassicality and entanglement
Jinyan Chen, Jackson Tiong, Lin Htoo Zaw +1
We introduce an even-parity precession protocol that can detect the nonclassicality of some quantum states using only measurements of a uniformly-precessing variable at different p…
Beating one bit of communication with quantum correlations in smaller dimensions
Peter Sidajaya, Valerio Scarani
As a consequence of Bell's theorem, the statistics of measurements on some entangled states cannot be simulated with local hidden variables alone. The amount of communication that…
Tsirelson's Inequality for the Precession Protocol is Maximally Violated by Quantum Theory
Lin Htoo Zaw, Mirjam Weilenmann, Valerio Scarani
The precession protocol involves measuring , the probability that a uniformly precessing observable (like the position of a harmonic oscillator or a coordinate undergoing spat…
