Emergent Unitary Designs for Encoded Qubits from Coherent Errors and Syndrome Measurements
Unitary k-designs are distributions of unitary gates that match the Haar distribution up to its kth statistical moment. They are a crucial resource for randomized quantum protocols. However, their implementation on encoded logical qubits is nontrivial due to the need for magic gates, which can requi...
