Quantum filtering for systems driven by fermion fields

J. E. Gough, M. I. Guta, M. R. James +1

Recent developments in quantum technology mean that is it now possible to manipulate systems and measure fermion fields (e.g. reservoirs of electrons) at the quantum level. This pr…

Fisher information and asymptotic normality in system identification for quantum Markov chains

Madalin Guta

This paper deals with the problem of estimating the coupling constant of a mixing quantum Markov chain. For a repeated measurement on the chain's output we show that the outcom…

Quantum U-statistics

Madalin Guta, Cristina Butucea

The notion of a -statistic for an -tuple of identical quantum systems is introduced in analogy to the classical (commutative) case: given a selfadjoint `kernel' acting on…

Quantum learning: optimal classification of qubit states

Madalin Guta, Wojciech Kotlowski

Pattern recognition is a central topic in Learning Theory with numerous applications such as voice and text recognition, image analysis, computer diagnosis. The statistical set-up…

Quantum teleportation benchmarks for independent and identically-distributed spin states and displaced thermal states

Madalin Guta, Peter Bowles, Gerardo Adesso

A successful state transfer (or teleportation) experiment must perform better than the benchmark set by the `best' measure and prepare procedure. We consider the benchmark problem…
