Autonomous Distribution of Programmable Multiqubit Entanglement in a Dual-Rail Quantum Network
Joan Agustí, Xin H. H. Zhang, Yuri Minoguchi +1
We propose and analyze a scalable and fully autonomous scheme for preparing spatially distributed multiqubit entangled states in a dual-rail waveguide QED setup. In this approach,…
Embedding of Time-Delayed Quantum Feedback in a Nonreciprocal Array
Xin H. H. Zhang, S. H. L. Klapp, A. Metelmann
Time-delayed quantum feedback is a fast and efficient method to control and stabilize few and many-body quantum systems. However, a proper understanding of such systems stays opaqu…
Driven-dissipative phase transition in a Kerr oscillator: From semiclassical symmetry to quantum fluctuations
Xin H. H. Zhang, Harold U. Baranger
We study a minimal model that has a driven-dissipative quantum phase transition, namely a Kerr non-linear oscillator subject to driving and dissipation. Using mean-field theory, ex…
Heralded Bell State of Dissipative Qubits Using Classical Light in a Waveguide
Xin H. H. Zhang, Harold U. Baranger
Maximally entangled two-qubit states (Bell states) are of central importance in quantum technologies. We show that heralded generation of a maximally entangled state of two intrins…
Quantum Interference and Complex Photon Statistics in Waveguide QED
Xin H. H. Zhang, H. U. Baranger
We obtain photon statistics by using a quantum jump approach tailored to a system in which one or two qubits are coupled to a one-dimensional waveguide. Photons confined in the wav…
