Super-Heisenberg scaling of the quantum Fisher information using spin-motion states
Venelin P. Pavlov, Peter A. Ivanov
We propose a spin-motion state for high-precision quantum metrology with super-Heisenberg scaling of the parameter estimation uncertainty using a trapped ion system. Such a highly…
Onset of Quantum Thermalization in Jahn-Teller model
Yoana R. Chorbadzhiyska, Peter A. Ivanov
We investigate the onset of quantum thermalization in a system governed by the Jahn-Teller Hamiltonian which describes the interaction between a single spin and two bosonic modes.…
Random Matrix Theory Approach to Quantum Fisher Information in Quantum Many-Body Systems
Venelin P. Pavlov, Yoana R. Chorbadzhiyska, Charlie Nation +2
We theoretically investigate parameter quantum estimation in quantum chaotic systems. Our analysis is based on an effective description of non-integrable quantum systems in terms o…
