Measuring the quality of a quantum reference frame: the relative entropy of frameness
Gilad Gour, Iman Marvian, Robert W. Spekkens
In the absence of a reference frame for transformations associated with a group G, any quantum state that is non-invariant under the action of G may serve as a token of the missing…
Building all Time Evolutions with Rotationally Invariant Hamiltonians
I. Marvian, R. B. Mann
All elementary Hamiltonians in nature are expected to be invariant under rotation. Despite this restriction, we usually assume that any arbitrary measurement or unitary time evolut…
Quantum mechanical description of measurement and the basic properties of state transformation
Iman Marvian
In this paper, without any priori assumption about the post-measurement state of system, we will examine how this state is restricted by assuming each of these following assumption…
How the quality of a received EPR pair depends on the distances from an EPR source?
A. Bayat, V. Karimipour, I. Marvian
Let an EPR source which generates maximally entangled pairs be located so that it has distances and to two users. After taking into account various effects like loss of…
