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…
Localizable Entanglement as an Order Parameter for Measurement-Induced Phase Transitions
Sourav Manna, Arul Lakshminarayan, Vaibhav Madhok
We identify localizable entanglement (LE) as an order parameter for measurement-induced phase transitions (MIPT). LE exhibits universal finite-size scaling with critical exponents…
Objectivity, basis ambiguity, and the classical simulability of concordant quantum computation
Bishal Kumar Das, Sourav Manna, Vaibhav Madhok
Concordant quantum computations, in which circuits whose register carries zero quantum discord with respect to every subsystem at every step, contain neither entanglement nor any o…
Quantum-to-classical transition and the emergence of trajectory level Darwinism with measurements distributed in time: a path integral approach
Harsh Arora, Bishal Kumar Das, Baladitya Suri +1
We present a formulation for the emergence of classical dynamics in a quantum world using a path integral approach that incorporates continuous measurements. Our approach complemen…
Information acquisition, scrambling, and sensitivity to errors in quantum chaos
Sreeram PG, Abinash Sahu, Naga Dileep Varikuti +3
Signatures of chaos can be understood by studying quantum systems whose classical counterpart is chaotic. However, the concepts of integrability, non-integrability and chaos extend…
