Nonexponential quantum decay under environmental decoherence
M. Beau, J. Kiukas, I. L. Egusquiza +1
An unstable quantum state generally decays following an exponential law, as environmental decoherence is expected to prevent the decay products from recombining to reconstruct the…
Continuous variable steering and incompatibility via state-channel duality
Jukka Kiukas, Costantino Budroni, Roope Uola +1
The term Einstein-Podolsky-Rosen steering refers to a quantum correlation intermediate between entanglement and Bell nonlocality, which has been connected to another fundamental qu…
Remote Parameter Estimation in a Quantum Spin Chain Enhanced by Local Control
Jukka Kiukas, Kazuya Yuasa, Daniel Burgarth
We study the interplay of control and parameter estimation on a quantum spin chain. A single qubit probe is attached to one end of the chain, while we wish to estimate a parameter…
