The process by which open quantum systems thermalize with an environment is both of funda-mental interest and relevant to noisy quantum devices. As a minimal model of this process, we consider a qudit chain evolving under local random unitaries and local depolarization channels. After mapping to a statistical mechanics model, the depolarization acts like a symmetry-breaking field, and we argue that it causes the system to thermalize within a time scale independent of system size. We show that… 
Random Quantum Circuits
Quantum circuits — built from local unitary gates and local measurements — are a new playground for quantum many-body physics and a tractable setting to explore universal collective phenomena

Emergent statistical mechanics of entanglement in random unitary circuits
We map the dynamics of entanglement in random unitary circuits, with finite on-site Hilbert space dimension $q$, to an effective classical statistical mechanics. We demonstrate explicitly the
GHZ extraction yield for multipartite stabilizer states
Let |Psi> be an arbitrary stabilizer state distributed between three remote parties, such that each party holds several qubits. Let S be a stabilizer group of |Psi>. We show that |Psi> can be
Integration with Respect to the Haar Measure on Unitary, Orthogonal and Symplectic Group
We revisit the work of the first named author and using simpler algebraic arguments we calculate integrals of polynomial functions with respect to the Haar measure on the unitary group U(d). The
