Experimental controlled-NOT gate simulation with thermal light
Tao Peng, Vincenzo Tamma, Yanhua H. Shih · Scientific Reports · 2016
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.
