From Adiabatic to Dispersive Readout of Quantum Circuits
(American Physical Society, 2020-08)
Spectral properties of a quantum circuit are efficiently read out by monitoring the resonance frequency shift it induces in a microwave resonator coupled to it. When the two systems are strongly detuned, theory attributes ...
Quantum gate arrays can be programmed to evaluate the expectation value of any operator
(American Physical Society, 2003-11)
A programmable gate array is a circuit whose action is controlled by input data. In this paper we describe a special-purpose quantum circuit that can be programmed to evaluate the expectation value of any operator O acting ...
Operações quânticas em circuitos fotônicos integrados: tomografia de estados e medidas de coerência
(Universidade Federal de Minas GeraisBrasilICX - DEPARTAMENTO DE FÍSICAPrograma de Pós-Graduação em FísicaUFMG, 2020-07-09)
This work proposes to carry out a study on integrated photonic circuits. Our goal is to develop a methodology for obtaining the parameters of a photonic circuit that allows us to perform a set of quantum operations necessary ...

Landau-Zener-Stückelberg interferometry in dissipative circuit quantum electrodynamics
(American Physical Society, 2020-06-15)
We study Landau-Zener-Stückelberg (LZS) interferometry in a cQED architecture under the effects of dissipation. To be specific, we consider a superconducting qubit driven by a dc + ac signal and coupled to a transmission ...
Generation of superposition states and charge-qubit relaxation probing in a circuit

CNOT Gate Mappings to Clifford+T Circuits in IBM Architectures
(2019-05-01)
IBM architectures impose some restrictions the quantum circuits that can be implemented. Only gates from Clifford+T gate library can be used and not all of the CNOT gates are available. Some of the CNOT need to be mapped ...
Quantum criticality and state engineering in the simulated anisotropic quantum Rabi model
(2018)
Promising applications of the anisotropic quantum Rabi model (AQRM) in broad parameter ranges are explored, which is realized with superconducting flux qubits simultaneously driven by two-tone time-dependent magnetic fields. ...
