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…

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…
