Full characterization of polarization states of light via direct
... The Dirac distribution is an underused but elegant way to describe a general quantum state. In particular, it is very useful for visualizing discrete systems. In our work, we use the ‘left’ phase-space representative of Chaturvedi et al.10 throughout, and discuss only the discrete (that is, N-level) ...

... More formally, is NP BQP? Contrary to almost every popular article ever written on the subject, most of us think the answer is no For “generic” combinatorial optimization problems, the situation seems similar to that of black-box model—where you only get the quadratic speedup of Grover’s algorithm ...

Few simple rules to fix the dynamics of classical systems using
... Rule 3:– If S is a closed system, the hamiltonian H of S must commute with those numberlike operators related to the observables which are not exchanged between S and R. The motivation is, again, rather natural: as we have seen in the Introduction, all the observables which commute with the hamilton ...

We study the Schrödinger, Heisenberg and Interaction picture for closed systems, define the density matrix and develop the master equation for open systems from its time evolution. As an example we establish the master equation ...

The indicated uncertainty accounts for a slight lack of symmetry between both channels of a polarimeter: We have found a, variation of +1/&& of the detection efficiencies when rotating the polarimeters. This spurious effect has been explained as small displacements of the light beam The effect of im ...
