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…

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…
