We derive several bounds on fidelity between quantum states. In particular we show that fidelity is bounded from above by a… (More)
We consider a family of vector and operator norms which we refer to as Schmidt norms. We show that these norms have several uses… (More)
Using the expression of the fidelity for the most general Gaussian quantum states, the quantum fidelity is studied for the states… (More)
In this paper we analyze the ground state phase diagram of a class of fermionic Hamiltonians by looking at the fidelity of ground… (More)
We explore the effect of a system’s symmetries on fidelity decay behavior. Chaos-like exponential fidelity decay behavior occurs… (More)

A noisy Gaussian channel is defined as a channel in which an input field mode is subjected to random Gaussian displacements in… (More)
We discuss quantum fidelity decay of classically regular dynamics, in particular for an important special case of a vanishing… (More)
We describe a protocol for continuously protecting unknown quantum states from decoherence that incorporates design principles… (More)
We derive a simple and general relation between the fidelity of quantum motion, characterizing the stability of quantum dynamics… (More)
