Mitigating quantum decoherence via global optimal control
Ashkan Abedi, Roberto Menta, Julien Despres +3
We show that global optimal control can drastically suppress the impact of decoherence in globally driven superconducting quantum computing architectures, taking as a prototype a r…
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…
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…
