A new expansion around mean field for the quantum Ising model
F. De Pasquale, S. M. Giampaolo
We show that an high temperature expansion at fixed order parameter can be derived for the quantum Ising model. The basic point is to consider a statistical generating functional a…

Quantum computing in a Spin ordered phase
F. de Pasquale, S. M. Giampaolo
We show that quantum computation can be performed in a system at thermal equilibrium if a spontaneous symmetry breaking occurs. The computing process is associated to the time evol…
