Generating uniform quantum state ensembles with continuous measurement
Theodore McKeever, Ahsan Nazir, Harry J. D. Miller
We investigate the generation of uniform quantum state ensembles via continuous measurement. Using the Bloch representation, we derive the associated Langevin and Fokker-Pl…
Optimal limits of continuously monitored thermometers and their Hamiltonian structure
Mohammad Mehboudi, Florian Meier, Marcus Huber +1
We investigate the fundamental and practical precision limits of thermometry in bosonic and fermionic environments by coupling an -level probe to them and continuously monitorin…
Curvature of Gaussian quantum states
Harry J. D. Miller
The space of quantum states can be endowed with a metric structure using the second order derivatives of the relative entropy, giving rise to the so-called Kubo-Mori-Bogoliubov inn…
Bypassing thermalization timescales in temperature estimation using prethermal probes
Nicholas Anto-Sztrikacs, Harry J. D. Miller, Ahsan Nazir +1
We introduce prethermal temperature probes for sensitive, fast and robust temperature estimation. While equilibrium thermal probes with a manifold of quasidegenerate excited states…
