Collective Vibronic Cascade in Cavity-Coupled Jahn-Teller Active Molecules
Suraj Kumar Pandit, Abhinay Pandey, Athreya Shankar +1
We study the polaritonic states and dynamics of multiple Jahn-Teller (JT) active molecules coupled to the modes of a Fabry-Perot cavity. We find that collective effects dramaticall…
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…
Parametric Amplification of Spin-Motion Coupling in Three-Dimensional Trapped-Ion Crystals
Samarth Hawaldar, N. Nikhil, Ana Maria Rey +2
Three-dimensional (3D) crystals offer a route to scale up trapped ion systems for quantum sensing and quantum simulation applications. However, engineering coherent spin-motion cou…
Adiabatic Cooling of Planar Motion in a Penning Trap Ion Crystal to Sub-Millikelvin Temperatures
Wes Johnson, Bryce Bullock, Athreya Shankar +3
Two-dimensional planar ion crystals in a Penning trap are a platform for quantum information science experiments. However, the low-frequency planar modes of these crystals are not…
Impedance-Engineered Josephson Parametric Amplifier with Single-Step Lithography
Lipi Patel, Samarth Hawaldar, Aditya Panikkar +2
We present the experimental demonstration of an impedance-engineered Josephson parametric amplifier (IEJPA) fabricated in a single-step lithography process. Impedance engineering i…
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…
Lieb-Mattis states for robust entangled differential phase sensing
Raphael Kaubruegger, Diego Fallas Padilla, Athreya Shankar +9
We explore a two-node, entanglement-enhanced sensor network for differential phase sensing that exploits decoherence-free subspaces to suppress common-mode noise, a primary limitat…
