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.…

Fast parametric two-qubit gates with suppressed residual interaction using a parity-violated superconducting qubit

Atsushi Noguchi, Alto Osada, Shumpei Masuda +7

We demonstrate fast two-qubit gates using a parity-violated superconducting qubit consisting of a capacitively-shunted asymmetric Josephson-junction loop under a finite magnetic fl…

Variational Quantum Gate Optimization

Kentaro Heya, Yasunari Suzuki, Yasunobu Nakamura +1

We propose a gate optimization method, which we call variational quantum gate optimization (VQGO). VQGO is a method to construct a target multi-qubit gate by optimizing a parametri…
