Frame-Based Filter-Function Formalism for Quantum Characterization and Control
Teerawat Chalermpusitarak, Behnam Tonekaboni, Yuanlong Wang +3
We introduce a theoretical framework for resource-efficient characterization and control of non-Markovian open quantum systems, which naturally allows for the integration of given,…
Restoring number conservation in quadratic bosonic Hamiltonians with dualities
Vincent P. Flynn, Emilio Cobanera, Lorenza Viola
Number-non-conserving terms in quadratic bosonic Hamiltonians can induce unwanted dynamical instabilities. By exploiting the pseudo-Hermitian structure built in to these Hamiltonia…
Deconstructing effective non-Hermitian dynamics in quadratic bosonic Hamiltonians
Vincent P. Flynn, Emilio Cobanera, Lorenza Viola
Unlike their fermionic counterparts, the dynamics of Hermitian quadratic bosonic Hamiltonians are governed by a generally non-Hermitian Bogoliubov-de Gennes effective Hamiltonian.…
