Permanent spin currents in cavity-qubit systems
Manas Kulkarni, Sven M. Hein, Eliot Kapit +1
In a recent remarkable experiment [P. Roushan et al., Nature Physics 13, 146 (2017)], a spin current in an architecture of three superconducting qubits was produced during a few mi…
Purification and switching protocols for dissipatively stabilized entangled qubit states
Sven M. Hein, Camille Aron, Hakan E. Türeci
Pure dephasing processes limit the fidelities achievable in driven-dissipative schemes for stabilization of entangled states of qubits. We propose a scheme which, combined with alr…
Time-delayed quantum coherent Pyragas feedback control of photon squeezing in a degenerate parametric oscillator
Manuel Kraft, Sven Moritz Hein, Judith Lehnert +3
Quantum coherent feedback control is a measurement-free control method fully preserving quantum coherence. In this paper we show how time-delayed quantum coherent feedback can be u…
Feedback-Induced Steady-State Light Bunching Above the Lasing Threshold
Franz Schulze, Benjamin Lingnau, Sven Moritz Hein +4
We develop a full quantum-optical approach for optical self-feedback of a microcavity laser. These miniaturized devices work in a regime between the quantum and classical limit and…
