Multilevel Electromagnetically Induced Transparency Cooling
Katya Fouka, Athreya Shankar, Ting Rei Tan +1
Electromagnetically Induced Transparency (EIT) cooling is a well-established method for preparing trapped ion systems in their motional ground state. However, isolating a three-lev…
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 ground-state cooling of two-dimensional trapped-ion crystals with more than 100 ions
Elena Jordan, Kevin A. Gilmore, Athreya Shankar +4
We study, both experimentally and theoretically, electromagnetically induced transparency cooling of the drumhead modes of planar 2-dimensional arrays with up to Be$…
Continuous real-time tracking of a quantum phase below the standard quantum limit
Athreya Shankar, Graham P. Greve, Baochen Wu +2
We propose a scheme for continuously measuring the evolving quantum phase of a collective spin composed of pseudospins. Quantum non-demolition measurements of a lossy cavity mo…
