Optimal Displacement Sensing with Spin-Dependent Squeezed States
Liam J. Bond, Christophe H. Valahu, Athreya Shankar +2
Displacement sensing is a fundamental task in metrology. However, the development of quantum-enhanced sensors that fully utilize the available degrees of freedom in many-body quant…
Programmable generation of arbitrary continuous-variable anharmonicities and nonlinear couplings
Teerawat Chalermpusitarak, Kai Schwennicke, Ivan Kassal +1
Harmonic oscillators are promising continuous-variable (CV) quantum resources because their infinite-dimensional Hilbert spaces allow for resource-efficient quantum computing and s…
Programmable quantum simulation of anharmonic dynamics
Cameron McGarry, Teerawat Chalermpusitarak, Kai Schwennicke +9
Continuous-variable-discrete-variable (CV-DV) quantum simulators offer a natural route to simulating bosonic dynamics relevant to many branches of physics and chemistry. However, p…
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…
