Optical coherent feedback control of a mechanical oscillator
Maryse Ernzer, Manel Bosch Aguilera, Matteo Brunelli +5
Feedback is a powerful and ubiquitous technique both in classical and quantum system control. Its standard implementation relies on measuring the state of a system, processing the…
Restoration of the non-Hermitian bulk-boundary correspondence via topological amplification
Matteo Brunelli, Clara C. Wanjura, Andreas Nunnenkamp
Non-Hermitian (NH) lattice Hamiltonians display a unique kind of energy gap and extreme sensitivity to boundary conditions. Due to the NH skin effect, the separation between edge a…
Quadrature nonreciprocity: unidirectional bosonic transmission without breaking time-reversal symmetry
Clara C. Wanjura, Jesse J. Slim, Javier del Pino +3
Nonreciprocity means that the transmission of a signal depends on its direction of propagation. Despite vastly different platforms and underlying working principles, the realisatio…
Unified Collision Model of Coherent and Measurement-based Quantum Feedback
Alfred Harwood, Matteo Brunelli, Alessio Serafini
We introduce a general framework, based on collision models and discrete CP-maps, to describe on an equal footing coherent and measurement-based feedback control of quantum mechani…
