Quantum Variational Optimization of Ramsey Interferometry and Atomic Clocks
Raphael Kaubruegger, Denis V. Vasilyev, Marius Schulte +2
We discuss quantum variational optimization of Ramsey interferometry with ensembles of entangled atoms, and its application to atomic clocks based on a Bayesian approach to pha…
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…
Photon Recoil Spectroscopy: Systematic Shifts and Nonclassical Enhancements
Marius Schulte, Niels Lörch, Piet O. Schmidt +1
In photon recoil spectroscopy, signals are extracted from recoils imparted by the spectroscopy light on the motion of trapped ions as demonstrated by C. Hempel et al., Nature Photo…
