Beating the thermal limit of qubit initialization with a Bayesian Maxwell's demon

Mark A. I. Johnson, Mateusz T. Mądzik, Fay E. Hudson +5

Fault-tolerant quantum computing requires initializing the quantum register in a well-defined fiducial state. In solid-state systems, this is typically achieved through thermalizat…

Phonon dynamics in SrFe2As2 and SrFeAsF parent pnictide compounds: How different/similar when compared to Ca- and Ba-compounds?

R. Mittal M. Zbiri, S. Rols, Y. Su +9

We report detailed measurements of temperature dependence and ab initio lattice dynamical calculations of the phonon density-of-states of two Sr based iron pnictide parent compound…
