Designs without disorder: unitary $k$ -designs from a single-site bulk defect

Samudra Sur, Pratik Nandy

We show that an $O (1)$ local defect is sufficient to generate approximate unitary $k$ -designs from an otherwise integrable quantum many-body system. Using a two-Pauli-kick (2PK) pr…

Unitary $k$ -designs without independent Hamiltonian quenches

Pratik Nandy

Unitary $k$ -designs provide a resource-efficient framework for emulating Haar randomness up to the $k$ -th order. Quench-based protocols have recently been shown to generate such de…
