@PRL Irreversibility and the emergence of the arrow of time in quantum systems
Entropy production, a quantity associated with the emergence of the arrow of time, has been successfully measured in a microscopic...
New two-way quantum-key-distribution prototocol
Within the broad research scenario of quantum secure communication, two-way quantum-key-distribution (TWQKD) is a relatively new proposal...
The role of coherent interactions in quantum metrology
It is well known that a quantum correlated probe can yield better precision in estimating an unknown parameter than classically possible....
@PRL The first experimental verification of fluctuation relations in "Quantum Thermodynamics&qu
Highlighted as Editors’ Suggestion. Research on the out-of-equilibrium dynamics of quantum systems has so far produced important...
Jonas Maziero (former PhD student) awarded the CAPES Thesis Prize
Our former PhD student, Dr Jonas Maziero was awarded a couple of prizes: (1) the best thesis Grand Prize in Natural Sciences...
Information Processing in NMR: theory and experiment
A new issue on Quantum information processing (QIP) in Nuclear Magnetic Resonance (NMR) was published in Philosophical Transactions of...
An NMR experiment on the full quantum version of the complementarity principle
One of the milestones of quantum mechanics is Bohr's complementarity principle. It states that a single quantum can exhibit a...
@PRL Experimental Estimate of a Classicality Witness via a Single Measurement
The perception that quantum correlations can still appear in separable states has opened exciting new possibilities regarding their use...
@PRL Witnessing the quantumness of correlations in NMR systems
The quantification of quantum correlations (other than entanglement) usually entails labored numerical optimization procedures also...
Nonadiabatic quantum computation by dynamic invariants
We introduce an approach for quantum computing in continuous time based on the Lewis–Riesenfeld dynamic invariants. This approach allows,...
