We report a recent experimental simulation of a controlled-NOT gate operation based on polarization correlation measurements of thermal fields in photon-number fluctuations. The interference between pairs of correlated paths at the very heart of these experiments has the potential for the simulation of correlations between a larger number of qubits.
We introduce a new factorization algorithm, based on the analogue determination of the periodicity of a single generalized continuous truncated exponential sum (CTES) interferogram. We demonstrate that this algorithm allows, in principle, to factorize arbitrary numbers exploiting a remarking rescaling property of the recorded CTES interference pattern. Such… (More)
