Nonuniversal Entanglement Level Statistics in Projection-driven Quantum Circuits
Lei Zhang, Justin A. Reyes, Stefanos Kourtis +3
We study the level-spacing statistics in the entanglement spectrum of output states of random universal quantum circuits where qubits are subject to a finite probability of project…
Ultra-slow dynamics in a translationally invariant spin model for multiplication and factorization
Lei Zhang, Stefanos Kourtis, Claudio Chamon +2
We construct a model of short-range interacting Ising spins on a translationally invariant two-dimensional lattice that mimics a reversible circuit that multiplies or factorizes in…
Geometric quantum discord of a Jaynes-Cummings atom and an isolated atom
Wen-Chao Qiang, Lei Zhang, Hua-Ping Zhang
We studied the geometric quantum discord of a quantum system consisted of a Jaynes- Cummings atom, a cavity and an isolated atom. The analytical expressions of the geometric quantu…
Geometric global quantum discord of two-qubit X states
Wen-Chao Qiang, Hua-Ping Zhanga, Lei Zhang
Xu [Jianwei Xu, J. Phys. A: Math. Theor. 45 405304 (2012)] generalized geometric quantum discord [B.Dakic, V. Vedral, and C . Brukner, Phys. Rev. Lett. 105 190502 (2010)] to multip…
