Efficient steady state entanglement generation in strongly driven coupled qubits
Ana Laura Gramajo, Daniel Domínguez, María José Sánchez
We report on a mechanism to optimize the generation of steady-state entanglement in a system of coupled qubits driven by microwave fields. Due to the interplay between Landau-Zener…
Quantum emulation of coherent backscattering in a system of superconducting qubits
Ana Laura Gramajo, Dan Campbell, Bharath Kannan +8
In condensed matter systems, coherent backscattering and quantum interference in the presence of time-reversal symmetry lead to well-known phenomena such as weak localization (WL)…
Revealing the system-bath coupling via Landau-Zener-Stückelberg interferometry in superconducting qubits
Ana Laura Gramajo, Daniel Dominguez, Maria Jose Sanchez
In this work we propose a way to unveil the type of environmental noise in strongly driven superconducting flux qubits through the analysis of the Landau-Zener-Stückelberg (LZS) in…
Amplitude tuning of steady state entanglement in strongly driven coupled qubits
Ana Laura Gramajo, Daniel Dominguez, Maria Jose Sanchez
In this work we report on a new mechanism to generate dissipative steady state entanglement in two coupled qubits driven by strong periodic ac fields. We show that steady entanglem…
Driving controlled entanglement in coupled flux qubits
Ana Laura Gramajo, Daniel Domínguez, María José Sánchez
We study the manipulation of quantum entanglement by periodic external fields. As an entanglement measure we compute numerically the concurrence of two flux qubits coupled inductiv…
