Integration of the Berry curvature on a qubit state manifold by coupling to a quantum meter system
Peng Xu, Shi-Liang Zhu, Klaus Mølmer +1
We present a scheme that allows integration of the Berry curvature and thus determination of the Chern number of a qubit eigenstate manifold. Our proposal continuously couples the…

Scalable quantum computing with qudits on a graph
E. O. Kiktenko, A. S. Nikolaeva, Peng Xu +2
We show a significant reduction of the number of quantum operations and the improvement of the circuit depth for the realization of the Toffoli gate by using qudits. This is done b…
