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…
Intermediate-temperature topological Uhlmann phase on IBM quantum computers
Christopher Mastandrea, Costin Iancu, Hao Guo +1
A spin-1 system can exhibit an intermediate-temperature topological regime with a quantized Uhlmann phase sandwiched by topologically trivial low- and high-temperature regimes. We…
Robustness and classical proxy of entanglement in variants of quantum walk
Christopher Mastandrea, Chih-Chun Chien
Quantum walk (QW) utilizes its internal quantum states to decide the displacement, thereby introducing single-particle entanglement between the internal and positional degrees of f…
Localization of quantum walk with classical randomness: Comparison between manual methods and supervised machine learning
Christopher Mastandrea, Chih-Chun Chien
A transition of quantum walk induced by classical randomness changes the probability distribution of the walker from a two-peak structure to a single-peak one when the random param…
