Quantum Cramer-Rao Precision Limit of Noisy Continuous Sensing
Dayou Yang, Moulik Ketkar, Koenraad Audenaert +2
Quantum sensors hold considerable promise for precision measurement, yet their capabilities are inherently constrained by environmental noise. A fundamental task in quantum sensing…
Asymptotic relaxation in quantum Markovian dynamics
Giovanni Di Meglio, Dariusz Chruściński, Koenraad Audenaert +2
We investigate the long-time behavior of quantum Markovian dynamics generated by time-dependent Gorini-Kossakowski-Lindblad-Sudarshan (GKLS) master equations. We introduce a notion…
Continuity bounds for quantum entropies arising from a fundamental entropic inequality
Koenraad Audenaert, Bjarne Bergh, Nilanjana Datta +3
We establish a tight upper bound for the difference in von Neumann entropies between two quantum states, and . This bound is expressed in terms of the von Neumann entrop…
Unlocking Heisenberg Sensitivity with Sequential Weak Measurement Preparation
T. B. Lantaño, Dayou Yang, K. M. R. Audenaert +2
We propose a state preparation protocol based on sequential measurements of a central spin coupled with a spin ensemble, and investigate the usefulness of the generated multi-spin…
A continuity bound for the expected number of connected components of a random graph: a model for epidemics
Koenraad Audenaert, Eric P. Hanson, Nilanjana Datta
We consider a stochastic network model for epidemics, based on a random graph proposed by Ross [Journal of Applied Probability, 18, 309-315 (1981)]. Members of a population occupy…
A Determinantal Inequality for the Geometric Mean with an Application in Diffusion Tensor Imaging
Koenraad M. R. Audenaert
We prove that for positive semidefinite matrices and the following determinantal inequality holds: \[ \det(I+A\#B)\le \det(I+A^{1/2}B^{1/2}), \] where is the geometr…
