Mitigating quantum decoherence via global optimal control
Ashkan Abedi, Roberto Menta, Julien Despres +3
The paper demonstrates that shaping a global drive in superconducting quantum processors can significantly reduce decoherence effects, improving the fidelity of one- and two-qubit…
Overcoming disorder in superconducting globally driven quantum computing
Riccardo Aiudi, Julien Despres, Roberto Menta +5
We study the impact of static disorder on a globally-controlled superconducting quantum computing architecture based on a quasi-two-dimensional ladder geometry [R. Menta et al., Ph…
Dynamics of the Bose-Hubbard Model Induced by On-Site or Long-Range Two-Body Losses
Julien Despres, Leonardo Mazza, Marco Schirò
We present a theoretical study of the dissipative dynamics of the Bose-Hubbard model induced by on-site or long-range two-body losses. We first consider the one-dimensional chain a…
Quench Spectroscopy for Dissipative and (Non)-Hermitian Quantum Lattice Models
Julien Despres
We extend the quench spectroscopy method to dissipative and isolated non-Hermitian quantum lattice models via the case study of the open Bose-Hubbard chain and the non-Hermitian tr…
Breakdown of Linear Spin-Wave Theory in a Non-Hermitian Quantum Spin Chain
Julien Despres, Leonardo Mazza, Marco Schirò
We present the spin-wave theory of the excitation spectrum and quench dynamics of the non-Hermitian transverse-field Ising model. The complex excitation spectrum is obtained for a…
