Control of Stochastic Quantum Dynamics by Differentiable Programming
Frank Schäfer, Pavel Sekatski, Martin Koppenhöfer +2
Control of the stochastic dynamics of a quantum system is indispensable in fields such as quantum information processing and metrology. However, there is no general ready-made appr…
Quantum Synchronization on the IBM Q System
Martin Koppenhöfer, Christoph Bruder, Alexandre Roulet
We report the first experimental demonstration of quantum synchronization. This is achieved by performing a digital simulation of a single spin- limit-cycle oscillator on the qu…
Heralded dissipative preparation of nonclassical states in a Kerr oscillator
Martin Koppenhöfer, Christoph Bruder, Niels Lörch
We present a heralded state preparation scheme for driven nonlinear open quantum systems. The protocol is based on a continuous photon counting measurement of the system's decay ch…
Quantum effects in amplitude death of coupled anharmonic self-oscillators
Ehud Amitai, Martin Koppenhöfer, Niels Lörch +1
Coupling two or more self-oscillating systems may stabilize their zero-amplitude rest-state, therefore quenching their oscillation. This phenomenon is termed "amplitude death". Wel…
