Integrated Nonlinear Photonics for Quantum Frequency Conversion

When
-

Abstract: 

Hybrid quantum networks rely on faithful quantum state transfer between disparate physics elements operating at dissimilar frequencies. Quantum frequency conversion bridges their frequency gaps by coherently manipulating the carrier frequency while maintaining the quantum correlations. The efficiency of frequency conversion is dictated by photon-photon interaction in a nonlinear optical media which is typically weak.

Abstract: We introduce averaged circuit eigenvalue sampling (ACES), a method for scalable noise metrology of quantum circuits that stands for Averaged Circuit Eigenvalue Sampling. It simultaneously estimates the individual error rates of all the gates in collections of quantum circuits, and can even account for space and time correlations between these gates. ACES strictly generalizes randomized benchmarking (RB), interleaved RB, simultaneous RB and several other related techniques.
