Irreversibility is a longstanding puzzle in physics. While microscopic laws of motion are invariant under time reversal, all macroscopic phenomena have a preferred direction in time. Heat, for instance, spontaneously flows from hot to cold. Eddington has called this as...

Dr  Tiago Batalhão (PhD student) was awarded the best thesis Grand Prize in Natural Sciences and Engineering 2017 afforded by CAPES and the Conrado Wessel Foundation (CWF). This is the most prestigious Brazilian Post-graduation Award. The prize includes a post-doctoral...

A new implementation of a Maxwell’s demon can control entropy production in a quantum-mechanical system that is driven out of thermal equilibrium. Maxwell’s demon explores the role of information in physical processes. Employing information about microscopic degrees of...

Entropy production, a quantity associated with the emergence of the arrow of time, has been successfully measured in a microscopic quantum system. Irreversibility is one of the most intriguing concepts in physics. While microscopic physical laws are perfectly reversibl...

Within the broad research scenario of quantum secure communication, two-way quantum-key-distribution (TWQKD) is a relatively new proposal for sharing secret keys that is not fully explored yet. We analyse the security of TWQKD schemes that use qubits prepared in non-or...

It is well known that a quantum correlated probe can yield better precision in estimating an unknown parameter than classically possible. However, how such a quantum probe should be measured remains somewhat elusive. We examine the role of measurements in quantum metro...

Highlighted as Editors’ Suggestion. Research on the out-of-equilibrium dynamics of quantum systems has so far produced important statements on the thermodynamics of small systems undergoing quantum mechanical evolutions. Key examples are provided by the Crooks and Jarz...

 A new issue on Quantum information processing (QIP) in Nuclear Magnetic Resonance (NMR) was published in Philosophical Transactions of the Royal Society. This was compiled and edited by Ivan S. Oliveira and Roberto M. Serra.
This special issue gathers the state-of-art...
