Unitary Designs of Symmetric Local Random Circuits
Yosuke Mitsuhashi, Ryotaro Suzuki, Tomohiro Soejima +1
We have established the method of characterizing the unitary design generated by a symmetric local random circuit. Concretely, we have shown that the necessary and sufficient condi…
Non-Haar random circuits form unitary designs as fast as Haar random circuits
Toshihiro Yada, Ryotaro Suzuki, Yosuke Mitsuhashi +1
The unitary design formation in random circuits has attracted considerable attention due to its wide range of practical applications and relevance to fundamental physics. While the…
More global randomness from less random local gates
Ryotaro Suzuki, Hosho Katsura, Yosuke Mitsuhashi +3
Random circuits giving rise to unitary designs are key tools in quantum information science and many-body physics. In this work, we investigate a class of random quantum circuits w…
