Continuous Time Quantum Walk Propagation for Irregular Temporal Graph Forecasting

Jiaqi Sun, Tianhao Li, Zhihao Bian

Continuous time quantum walks built on graph Laplacians produce non monotonic graph propagation features through quantum interference during evolution, which classical diffusion ca…

An experimental proposal certification for any three-qubit generalized Greenberger-Horne-Zeilinger states based on the fine-grained steering inequality

Zhi-Hao Bian, Jia-Qi Sun, Yi Shen

Multi-party quantum steering is an important concept in quantum information theory and quantum mechanics, typically related to quantum entanglement and quantum nonlocality. It enab…

The detection power of real entanglement witnesses under local unitary equivalence

Yi Shen, Lin Chen, Zhihao Bian

The imaginary unit has recently been experimentally proven to be indispensable for quantum mechanics. We study the differences in detection power between real and complex entan…

Quantum information dynamics in a high-dimensional parity-time-symmetric system

Zhihao Bian, Lei Xiao, Kunkun Wang +5

Non-Hermitian systems with parity-time () symmetry give rise to exceptional points (EPs) with exceptional properties that arise due to the coalescence of eigenvectors…

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…
