Quantum circuits for exact unitary $t$ -designs and applications to higher-order randomized benchmarking

Yoshifumi Nakata, Da Zhao, Takayuki Okuda +9

A unitary $t$ -design is a powerful tool in quantum information science and fundamental physics. Despite its usefulness, only approximate implementations were known for general $t$ .…

On the explicit constructions of certain unitary $t$ -designs

Eiichi Bannai, Mikio Nakahara, Da Zhao +1

Unitary $t$ -designs are `good' finite subsets of the unitary group $U (d)$ that approximate the whole unitary group $U (d)$ well. Unitary $t$ -designs have been applied in randomized…
