## @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 statements on the thermodynamics of small systems undergoing quantum mechanical evolutions. Key examples are provided by the Crooks and Jarzynski relations: taking into account fluctuations in non-equilibrium dynamics, such relations connect equilibrium properties of thermodynamic relevance with explicit non-equilibrium features. Although the experi

## 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 the Royal Society. This was compiled and edited by Ivan S. Oliveira and Roberto M. Serra.
This special issue gathers the state-of-art of NMR-QIP. It covers new experimental techniques, which combine NMR and EPR, perspectives for NMR-QIP in Solid-State and implementation of quantum algorithms and protocols in liquid-state samples, including qu

## 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 particlelike or a wavelike behavior, but never both at the same time. These are mutually exclusive and complementary aspects of the quantum system. This means that we need distinct experimental arrangements in order to measure the particle or the wave nature of a physical system. One of the most known representations of this principle is the single-pho

## 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 much more easily manipulated and measured. In this sense, the development of quantum computing is gaining further significance as a valuable tool that sheds light on difficult problems studied from a new viewpoint. Perhaps, the most important feature here is the fact quantum simulators would not only provide new results (hardly achievable clas

## @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 as a resource in quantum information science. Quantifying such quantum correlations involves the complete knowledge of the system’s state and numerical optimization procedures. Thus, it is natural to seek methods involving fewer measurements that indicate the nature of the correlations in a system. Here we propose a classicality witness that

## @PRL Witnessing the quantumness of correlations in NMR

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 report recently a direct experimental implementation of such a witness in a room temperature nuclear magnetic resonance (NMR) system. In our experiment the nature of correlations is revealed by performing on

## Nonadiabatic quantum computation by dynamic invariants

We have introduced an approach for quantum computing based on the theory of dynamic invariants. Such an approach is a shortcut to adiabatic quantum computation, recovering the last as a particular case. We show that the relaxation of adiabaticity in a continuous evolution setting can be achieved by processing information in the eigenlevels of a time dependent observable, namely, the dynamic invariant operator. Moreover, we derive the conditions for which the computation can b

## Sudden-change dynamics of quantum discord

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 has been increasing in relevance in several fields, among them quantum communication, quantum computation, quantum phase transitions, and biological systems. We demonstrate here the occurrence of the sudden-cha
