Stochastic Estimation of Dynamical Variables
Stefan Krastanov, Sisi Zhou, Steven T. Flammia +1
Estimating the parameters governing the dynamics of a system is a prerequisite for its optimal control. We present a simple but powerful method that we call STEADY, for STochastic…
Quantum repeaters based on two species trapped ions
Siddhartha Santra, Sreraman Muralidharan, Martin Lichtman +3
We examine the viability of quantum repeaters based on two-species trapped ion modules for long distance quantum key distribution. Repeater nodes comprised of ion-trap modules of c…
Universal quantum computing with parafermions assisted by a half fluxon
Arpit Dua, Boris Malomed, Meng Cheng +1
Braiding of anyons such as Majoranas or parafermions provides only Clifford gates which do not form a universal set of quantum gates. We propose a robust and resource-efficient sch…
Lindbladians with multiple steady states: theory and applications
Victor V. Albert
Markovian master equations, often called Liouvillians or Lindbladians, are used to describe decay and decoherence of a quantum system induced by that system's environment. While a…
