Canceling the cavity length induced phase noise in an optical ring cavity for phase shift measurement and spin squeezing
Enlong Wang, Gunjan Verma, Jonathan N. Tinsley +2
We demonstrate a new method of light phase shift measurement using a high-finesse optical ring cavity which exhibits reduced phase noise due to cavity length fluctuations. Two lase…
Sr atom interferometry with the optical clock transition as a gravimeter and a gravity gradiometer
Liang Hu, Enlong Wang, Leonardo Salvi +3
We characterize the performance of a gravimeter and a gravity gradiometer based on the S-P clock transition of strontium atoms. We use this new quantum sensor t…
Squeezed state metrology with Bragg interferometers operating in a cavity
Athreya Shankar, Leonardo Salvi, Maria Luisa Chiofalo +2
Bragg interferometers, operating using pseudospin-1/2 systems composed of two momentum states, have become a mature technology for precision measurements. State-of-the-art Bragg in…
Near-Unitary Spin Squeezing in Yb
Boris Braverman, Akio Kawasaki, Edwin Pedrozo-Peñafiel +9
Spin squeezing can improve atomic precision measurements beyond the standard quantum limit (SQL), and unitary spin squeezing is essential for improving atomic clocks. We report sub…
Geometrically asymmetric optical cavity for strong atom-photon coupling
Akio Kawasaki, Boris Braverman, Edwin Pedrozo-Peñafiel +11
Optical cavities are widely used to enhance the interaction between atoms and light. Typical designs using a geometrically symmetric structure in the near-concentric regime face a…
Atom interferometry with the Sr optical clock transition
Liang Hu, Nicola Poli, Leonardo Salvi +1
We report on the realization of a matter-wave interferometer based on single-photon interaction on the ultra-narrow optical clock transition of strontium atoms. We experimentally d…
