@Nat. Comm. Physics: Assessing physical realism experimentally in a quantum-controlled device
Bohr’s complementarity principle has been challenged by quantum delayed-choice experiments wherein quantum systems are claimed to behave...

@PRL Experimental Validation of Fully Quantum Fluctuation Theorems
Fluctuation theorems are fundamental extensions of the second law of thermodynamics for small systems. Their general validity arbitrarily...

@PRL Easy Access to Energy Fluctuations
A new article combined theoretical and experimental efforts to propose a method for studying energy fluctuations, in particular, to...

@PRL Quantum engine operating at maximum power
A new experimental proof-of-concept quantum Otto cycle, using nuclear spins, has reached an efficiency close to its thermodynamic limit...

@Nature Communications: Reversion of heat flow using quantum correlations
Irreversibility is a longstanding puzzle in physics. While microscopic laws of motion are invariant under time reversal, all macroscopic...

@PRL High-Dimensional Quantum Communication Complexity
Quantum resources can improve communication complexity problems (CCPs) beyond their classical constraints. One quantum approach is to...

@PRL Second Law in an Optical Cavity and a BEC
In the continuum from quantum to classical, there exists a paradox. Classical machines like heaters cannot run in reverse (and...

Tiago Batalhão awarded the CAPES Best Thesis Prize
Dr Tiago Batalhão (our former PhD student) was awarded the best thesis Grand Prize in Natural Sciences and Engineering 2017 afforded...

@PRL Maxwell’s Demon Meets Nonequilibrium Quantum Thermodynamics
A new implementation of a Maxwell’s demon can control entropy production in a quantum-mechanical system that is driven out of thermal...

@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...

@PRA 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...

@NJP 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 and...

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...

@PRA 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...

Quantum simulation of protons and neutrons
The interest in quantum simulation is manifold. Properties of the simulated system are gathered by dealing with other systems that are...
