Discrete coherent states for n qubits
C. Munoz, A. B. Klimov, L. L. Sanchez-Soto +1
Discrete coherent states for a system of qubits are introduced in terms of eigenstates of the finite Fourier transform. The properties of these states are pictured in phase spa…
On the structure of the sets of mutually unbiased bases for N qubits
J. L. Romero, G. Bjork, A. B. Klimov +1
For a system of N qubits, spanning a Hilbert space of dimension d=2^N, it is known that there exists d+1 mutually unbiased bases. Different construction algorithms exist, and it is…
Distance-based degrees of polarization for a quantum field
A. B. Klimov, L. L. Sanchez-Soto, E. C. Yustas +2
It is well established that unpolarized light is invariant with respect to any SU(2) polarization transformation. This requirement fully characterizes the set of density matrices r…
Quantum phases of a qutrit
A. B. Klimov, L. L. Sanchez-Soto, H. de Guise +1
We consider various approaches to treat the phases of a qutrit. Although it is possible to represent qutrits in a convenient geometrical manner by resorting to a generalization of…
