Easy access to energy fluctuations in non-equilibrium quantum many-body systems

Marcela Herrera, John P. S. Peterson, Roberto M. Serra +1

We combine theoretical and experimental efforts to propose a method for studying energy fluctuations, in particular, to obtain the related bi-stochastic matrix of transition probab…

Implementation of a Quantum Engine Fuelled by Information

John P. S. Peterson, Roberto S. Sarthour, Raymond Laflamme

Here, we show the implementation of a complete cycle of a quantum engine fuelled by information. This engine is a quantum version of the Szilard engine, where information is used t…

Fast Simulation of Magnetic Field Gradients for Optimization of Pulse Sequences

John P. S. Peterson, Hemant Katiyar, Raymond Laflamme

We study how to simulate, efficiently, pulse field gradients (PFG) used in nuclear magnetic resonance (NMR). An efficient simulation requires discretization in time and space. We s…

Enhancing quantum control by improving shape pulse generation

John P. S. Peterson, Roberto S. Sarthour, Raymond Laflamme

Most quantum processors requires pulse sequences for controlling quantum states. Here, we present an alternative algorithm for computing an optimal pulse sequence in order to perfo…

Experimental characterization of a spin quantum heat engine

John P. S. Peterson, Tiago B. Batalhão, Marcela Herrera +4

Developments in the thermodynamics of small quantum systems envisage non-classical thermal machines. In this scenario, energy fluctuations play a relevant role in the description o…
