Stationary optomechanical entanglement between a mechanical oscillator and its measurement apparatus
C. Gut, K. Winkler, J. Hoelscher-Obermaier +9
We provide an argument to infer stationary entanglement between light and a mechanical oscillator based on continuous measurement of light only. We propose an experimentally realiz…
Correlating photons using the collective nonlinear response of atoms weakly coupled to an optical mode
Adarsh S. Prasad, Jakob Hinney, Sahand Mahmoodian +6
Photons in a nonlinear medium can repel or attract each other, resulting in a strongly correlated quantum many-body system. Typically, such strongly correlated states of light aris…
Robust and resource-efficient microwave near-field entangling Be gate
G. Zarantonello, H. Hahn, J. Morgner +5
Microwave trapped-ion quantum logic gates avoid spontaneous emission as a fundamental source of decoherence. However, microwave two-qubit gates are still slower than laser-induced…
Ramsey interferometry with generalized one-axis twisting echoes
Marius Schulte, Victor J. Martínez-Lahuerta, Maja S. Scharnagl +1
We consider a large class of Ramsey interferometry protocols which are enhanced by squeezing and un-squeezing operations before and after a phase signal is imprinted on the collect…
Prospects and challenges for squeezing-enhanced optical atomic clocks
Marius Schulte, Christian Lisdat, Piet O. Schmidt +2
We have investigated the benefits of spin squeezed states for clocks operated with typical Brownian frequency noise-limited laser sources. Based on an analytic model of the closed…
Dynamics of many-body photon bound states in chiral waveguide QED
Sahand Mahmoodian, Giuseppe Calajó, Darrick E. Chang +2
We theoretically study the few- and many-body dynamics of photons in chiral waveguides. In particular, we examine pulse propagation through a system of two-level systems chiral…
