Ground- and excited-state energies extraction via Trotterization on IBM quantum computers
Fernando Espinoza-Ortiz, Chungwei Lin, Chih-Chun Chien
We implement the Hadamard test with Trotterized time-evolution operators on IBM quantum computers to simultaneously extract ground- and excited-state energies of the transverse fie…
Spatial and particle-particle entanglement in 1D quantum walks of two distinguishable or indistinguishable bosonic particles
Christopher Mastandrea, Chih-Chun Chien
We present entanglement measures between spatially separated regions and between two distinguishable or indistinguishable particles in one-dimensional two-particle continuous-time…
Geometry near rank-changing points on the mixed-state manifold: Bures metric, conical singularities, and Lindblad dynamics
Yu-Huan Huang, Xu-Yang Hou, Hao Guo +1
We elucidate the Bures metric in quantum state space near a rank-changing point of the density matrix and show contrasting behavior for two-level () systems versus higher-leve…
