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…
