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…

Teleportation of squeezing: Optimization using non-Gaussian resources

F. Dell'Anno, S. De Siena, G. Adesso +1

We study the continuous-variable quantum teleportation of states, statistical moments of observables, and scale parameters such as squeezing. We investigate the problem both in ide…

Hawking Radiation on an Ion Ring in the Quantum Regime

Birger Horstmann, Ralf Schützhold, Benni Reznik +2

This paper discusses a recent proposal for the simulation of acoustic black holes with ions. The ions are rotating on a ring with an inhomogeneous, but stationary velocity profile.…

Quantum accelerometer: distinguishing inertial Bob from his accelerated twin Rob by a local measurement

Andrzej Dragan, Ivette Fuentes, Jorma Louko

Single quantum system, such as Unruh-DeWitt detector, can be used to determine absolute acceleration by local measurements on a quantum field. To show this, we consider two kinemat…

Entangling moving cavities in non-inertial frames

T. G. Downes, I. Fuentes, T. C. Ralph

An open question in the field of relativistic quantum information is how parties in arbitrary motion may distribute and store quantum entanglement. We propose a scheme for storing…

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…
