Memory-assisted squeezed light velocimetry under realistic loss and incoherent noise
Mustafa Gündoğan, Arash Ahmadi, Markus Krutzik
We propose a velocity sensor based on a two-memory Mach--Zehnder interferometer fed by a coherent probe and squeezed vacuum, read out by balanced homodyne detection. One memory is…
Generation of squeezed optical states via stored classical pulses in a Bose gas
Sevilay Sevinçli, Dennis Rätzel, Markus Krutzik +2
We propose and analyze a scheme to generate squeezed light by storing a classical probe pulse in a Bose--Einstein condensate (BEC) and exploiting the nonlinear evolution caused by…
Gravitational time dilation in quantum clock interferometry with entangled multi-photon states and quantum memories
Mustafa Gündoğan, Roy Barzel, Dennis Rätzel
Gravitational time dilation implies that clocks held at different heights accumulate different proper times. We analyze a memory-assisted quantum clock interferometer in which a fr…
Controlled Displacement of Stored Light at Room Temperature
Arash Ahmadi, Yağız Murat, Pei-Chen Kuan +2
We report the demonstration of spatially translating a stored optical pulse at room temperature over distances exceeding one optical wavelength. By implementing an interferometric…
