Direct Experimental Test of Forward and Reverse Uncertainty Relations

Lei Xiao, Bowen Fan, Kunkun Wang +2

The canonical Robertson-Schrödinger uncertainty relation provides a loose bound for the product of variances of two non-commuting observables. Recently, several tight forward and r…

Dynamic process and Uhlmann process: Incompatibility and dynamic phase of mixed quantum states

Hao Guo, Xu-Yang Hou, Yan He +1

While a pure quantum state may accumulate both the Berry phase and dynamic phase as it undergoes a cyclic path in the parameter space, the situation is more complicated when mixed…

Experimental orthogonalization of highly overlapping quantum states with single photons

Gaoyan Zhu, Orsolya Kalman, Kunkun Wang +6

We experimentally realize a nonlinear quantum protocol on single-photon qubits with linear optical elements and appropriate measurements. The quantum nonlinearity is induced by pos…

Computer-inspired concept for high-dimensional multipartite quantum gates

Xiaoqin Gao, Manuel Erhard, Anton Zeilinger +1

An open question in quantum optics is how to manipulate and control complex quantum states in an experimentally feasible way. Here we present concepts for transformations of high-d…

Quantum Circuit Transformation Based on Simulated Annealing and Heuristic Search

Xiangzhen Zhou, Sanjiang Li, Yuan Feng

Quantum algorithm design usually assumes access to a perfect quantum computer with ideal properties like full connectivity, noise-freedom and arbitrarily long coherence time. In No…

Conserved quantities in parity-time symmetric systems

Zhihao Bian, Lei Xiao, Kunkun Wang +6

Conserved quantities such as energy or the electric charge of a closed system, or the Runge-Lenz vector in Kepler dynamics are determined by its global, local, or accidental symmet…

The quantum algorithm for graph isomorphism problem

Xi Li, Hanwu Chen

The graph isomorphism (GI) problem is the computational problem of finding a permutation of vertices of a given graph that transforms to another given graph and p…
