Short Bio

 

I run a quantum information science and technology research group at UFABC, in the São Paulo metropolitan area, known as ABC region in Brazil. I obtained my PhD in Physics from UFSCar (São Carlos, Brazil) and performed postdoctoral research at Imperial College London (UK). I was an associate member of the ICTP in Trieste (Italy). I also was a Royal Society ‘Newton Advanced Fellow’ of the  University of York (UK). My research interest is quite broad concerning quantum mechanics and its implications for information science or vice-versa. Such interest also embraces the under-building quantum thermodynamics. I am involved with both theoretical and experimental research. I have a penchant for the exciting challenge of translating abstract theoretical ideas to a laboratory setting. Part of my free time is dedicated to home brewing; exploring different flavours that arising from new hops and malted barley combinations.

Research Highlights

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...

Our  former  PhD  student,  Dr  Jonas  Maziero  was  awarded a couple  of  prizes: (1) the best thesis Grand Prize in Natural Sciences and Engineering awarded by the Coordination for the Improvement of Higher Education Personnel (CAPES) and the Conrado Wessel Foundatio...

 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...

One of the milestones of quantum mechanics is Bohr's complementarity principle. It states that a single quantum can exhibit a particlelike or a wavelike behavior, but never both at the same time. These are mutually exclusive and complementary aspects of the quantum sys...

The perception that quantum correlations can still appear in separable states has opened exciting new possibilities regarding their use as a resource in quantum information science. Quantifying such quantum correlations involves the complete knowledge of the system’s s...

The quantification of quantum correlations (other than entanglement) usually entails labored numerical optimization procedures also demanding quantum state tomographic methods. Thus it is interesting to have a laboratory friendly witness for the nature of correlations....

We introduce an approach for quantum computing in continuous time based on the Lewis–Riesenfeld dynamic invariants. This approach allows, under certain conditions, for the design of quantum algorithms running on a nonadiabatic regime. We show that the relaxation of adi...

Nonclassical correlations play a crucial role in the development of quantum information science. The recent discovery that nonclassical correlations can be present even in separable (nonentangled) states has broadened this scenario. This generalized quantum correlation...
