Local asymptotic equivalence of pure states ensembles and quantum Gaussian white noise (2018)
Journal Article
Butucea, C., Gu??, M., & Nussbaum, M. (2018). Local asymptotic equivalence of pure states ensembles and quantum Gaussian white noise. Annals of Statistics, 46(6B), 3676-3706. https://doi.org/10.1214/17-aos1672

Quantum technology is increasingly relying on specialised statistical inference methods for analysing quantum measurement data. This motivates the development of “quantum statistics”, a field that is shaping up at the overlap of quantum physics and “...

Catching and reversing quantum jumps and thermodynamics of quantum trajectories (2018)
Journal Article
Garrahan, J. P., & Guta, M. (2018). Catching and reversing quantum jumps and thermodynamics of quantum trajectories. Physical Review A, 98(5), https://doi.org/10.1103/PhysRevA.98.052137

A recent experiment by Minev et. al [arXiv:1803.00545] demonstrated that in a dissipative (artificial) 3-level atom with strongly intermittent dynamics it is possible to " catch and reverse " a quantum jump " mid-flight " : by the conditional applica...

Minimax estimation of qubit states with Bures risk (2018)
Journal Article
Acharya, A., & Gu??, M. (2018). Minimax estimation of qubit states with Bures risk. Journal of Physics A: Mathematical and Theoretical, 51(17), 1-27. https://doi.org/10.1088/1751-8121/aab6f2

The central problem of quantum statistics is to devise measurement schemes for the estimation of an unknown state, given an ensemble of n independent identically prepared systems. For locally quadratic loss functions, the risk of standard procedures... Read More about Minimax estimation of qubit states with Bures risk.
