Fast pseudorandom quantum state generators via inflationary quantum gates
Abstract We propose a mechanism for reaching pseudorandom quantum states, computationally indistinguishable from Haar random, with shallow log-n depth quantum circuits, where n is the number of qudits. We argue that $$\log n$$ log n depth 2-qubit-gate-based generic random quantum circuits that are c...
