Quantum circuits for exact unitary -designs and applications to higher-order randomized benchmarking
Yoshifumi Nakata, Da Zhao, Takayuki Okuda +9
A unitary -design is a powerful tool in quantum information science and fundamental physics. Despite its usefulness, only approximate implementations were known for general .…
One-shot quantum error correction of classical and quantum information
Yoshifumi Nakata, Eyuri Wakakuwa, Hayata Yamasaki
Quantum error correction (QEC) is one of the central concepts in quantum information science and also has wide applications in fundamental physics. The capacity theorems provide so…
Explicit construction of exact unitary designs
Eiichi Bannai, Yoshifumi Nakata, Takayuki Okuda +1
The purpose of this paper is to give explicit constructions of unitary -designs in the unitary group for all and . It seems that the explicit constructions were so…
Holographic Pseudo Entropy
Yoshifumi Nakata, Tadashi Takayanagi, Yusuke Taki +2
We introduce a quantity, called pseudo entropy, as a generalization of entanglement entropy via post-selection. In the AdS/CFT correspondence, this quantity is dual to areas of min…
Thermal robustness of multipartite entanglement of the 1-D spin 1/2 XY model
Yoshifumi Nakata, Damian Markham, Mio Murao
We study the robustness of multipartite entanglement of the ground state of the one-dimensional spin 1/2 XY model with a transverse magnetic field in the presence of thermal excita…
