Non-Kolmogorov-Arnold-Moser Quantum Sensors for Quantum Parameter Estimation
Naga Dileep Varikuti, Sourav Manna, Athreya Shankar +2
Non-KAM (Kolmogorov-Arnold-Moser) systems, when subjected to weak time-dependent perturbations, exhibit an abrupt transition to classical chaos through the breakdown of invariant p…
Quantum-enhanced single and multiparameter metrology in qutrit ensembles by generalized twisting dynamics
Deep Datta, Sayam Chakraborty, John Drew Wilson +2
Quantum-enhanced sensing with atomic ensembles has predominantly focused on qubit-based protocols, despite the growing ability of many experimental platforms to coherently control…
Programmable coherent site-selective spin control in rotating Penning-trap ion crystals
Nihar Makadia, Julian Y. Z. Jee, Gustavo Café de Miranda +4
Large ion crystals in Penning traps provide a platform for quantum simulation and sensing with hundreds of spins, but their continuous rigid-body rotation has so far limited flexib…
Quantum Beam-Splitter Cooling and Thermometry in Large Trapped-Ion Crystals
Kirthik Rajakumar, Ansh Das, Abhinay Pandey +1
We propose and characterize a protocol for rapid near-ground state cooling of the center-of-mass (c.m.) mode of a large trapped ion crystal. When the initial mean thermal occupatio…
Dynamical aspects of steady-state subradiance: Detailed balance and its breakdown
Athreya Shankar, Simon B. Jäger, Jarrod T. Reilly +3
The dynamics of dissipative many-body quantum systems sometimes admit an emergent classical description in terms of a Markov chain even though the corresponding state space contain…
Experimental realisation of topological spin textures in a Penning trap
Julian Y. Z. Jee, Nihar Makadia, Joseph H. Pham +4
Quantum simulation with controllable many-body platforms offers a powerful route to exploring complex phases and dynamics that are difficult to access in natural materials. Among t…
