Introduces a minimal matchgate circuit representation for fermionic Gaussian states together with a Yang-Baxter update algorithm, then maps out entanglement transitions in unitary circuit games under braiding and generic matchgate rules.
Develops an optimization-free disentangling algorithm and algebraic criterion for efficient CAMPS representations of Clifford circuits doped with αI+βP gates, enabling polynomial classical simulation for more circuits including typical N-T-gate random instances.
Thermal operations can generate nonstabiliser states from stabilizer states, with an analytic characterization for qubits and a general trade-off between attainable nonstabiliserness and initial free energy.
Provides a theoretical overview of Majorana-based topological quantum computing and introduces a time-dependent Pfaffian simulation method for braiding, projective measurements, and disorder.
Authors propose a low-optical-depth fusion-based photonic quantum computing architecture using quantum-dot emitters, adaptive repeat-until-success fusions, and time-bin qubits, with resource estimates and error-threshold simulations for fault tolerance.
Non-Hermitian and dissipative dynamics engineer magic steady states in qubits that attract every initial state to high-magic targets.
