Research output: Contribution to journalArticlepeer-review

76 Scopus citations


The entanglement length in d-dimensional noisy quantum computers was investigated. A phase transition in entanglement occurred at a critical noise rate where the entanglement rate transformed from infinite to finite. Macroscopic classical behavior was depicted above the rate microscopically distant subsystems were entangled above the rate.
