Unveiling a Hidden Percolation Transition in Monitored Clifford Circuits: Inroads from ZX Calculus

Author(s): Einat Buznach Ahituv, Jonathan Ruhman, and Debanjan Chowdhury We revisit the measurement-induced phase transition (MPT) in Clifford circuits, which are both classically simulable and exhibit critical behavior widely believed to be distinct from classical percolation theory, using ZX calculus. We analyze the MPT in a dynamical model composed of controlled not (… [Phys. Rev. Lett. 135, 050402] Published Wed Jul 30, 2025
