Depth-1 distinctness for pseudorandom unitaries
The paper proves that a tensor-product ensemble of independently chosen single-qubit Clifford gates is -distinct when the number of queries is polynomial in . This disproves the authors' conjecture that negligibly distinct ensembles must necessarily be entangling. As an application, the depth- global Clifford/unitary--design layer used in the pseudorandom-unitary construction can be replaced by a single depth-1 layer of local single-qubit -designs while preserving the required distinctness property.
