Circulant matrices, gauss sums and mutually unbiased I. The prime number case
M. Combescure
In this paper, we consider the problem of Mutually Unbiased Bases in prime dimension . It is known to provide exactly mutually unbiased bases. We revisit this problem usin…

Quadratic Quantum Hamiltonians revisited
Monique Combescure, Didier Robert
Time dependent quadratic Hamiltonians are well known as well in classical mechanics and in quantum mechanics. In particular for them the correspondance between classical and quantu…

The quantum fidelity for the time-dependent singular quantum oscillator
M. Combescure
In this paper we perform an exact study of ``Quantum Fidelity'' (also called Loschmidt Echo) for the time-periodic quantum Harmonic Oscillator of Hamiltonian : $$ \hat H\_{g}(t):=\…
