Quantum phase estimation for nondestructive monitoring and Wigner tomography of bosonic fields

Lucas R. S. Santos, Ciro M. Diniz, Daniel Z. Rossatto +1

Quantum phase estimation is usually introduced as an algorithmic primitive for extracting eigenphases of unitary operators. Here we show that, when implemented through a dispersive…

Trapped-ion toolbox to simulate quantum Otto heat engines

Rogério Jorge de Assis, Ciro Micheletti Diniz, Norton Gomes de Almeida +1

We present a scheme that utilizes an ion confined within a bi-dimensional trap to simulate a quantum Otto heat engine whose working substance is a two-level system. In this scheme,…
