A Quantum Paradox of Choice: More Freedom Makes Summoning a Quantum State Harder
(American Physical SocietyPhysical Review A, 2016)
The properties of quantum information in space-time can be investigated by studying operational tasks, such as ‘summoning’, in which an unknown quantum state is supplied at one point, and a call is made at another for it ...
Charmonium and charmed meson spectroscopy from lattice QCD
(Proceedings of Science34th annual International Symposium on Lattice Field Theoryhttps://pos.sissa.it/cgi-bin/reader/contribution.cgi?id=256/137, 2017-01-25)
Spectra of highly excited hidden and open-charm mesons calculated on dynamical lattice QCD ensembles with a pion mass of M$_{π}$ $\sim$ 240 MeV are presented and compared to previous results obtained on a lattice where ...
Universal Charge Diffusion and the Butterfly Effect in Holographic Theories
(American Physical SocietyPhysical Review Letters, 2016-08-23)
We study charge diffusion in holographic scaling theories with a particle-hole symmetry. We show that these theories have a universal regime in which the diffusion constant is given by D$_{c}$ = Cv$^{2}$$_{B}$/(2πT), where ...
Joint Tracking of Manoeuvring Targets and Classification of Their Manoeuvrability
(2004-11-07)
Semi-Markov models are a generalisation of Markov models that explicitly model the state-dependent sojourn time distribution, the time for which the system remains in a given state. Markov models result in an exponentially ...
