Derivation of Standard Quantum Theory via State Discrimination
Hayato Arai, Masahito Hayashi
It is a key issue to characterize the model of standard quantum theory out of general models by an operational condition. The framework of General Probabilistic Theories (GPTs) is…
When quantum memory is useful for dense coding
Ryuji Takagi, Masahito Hayashi
We discuss dense coding with copies of a specific preshared state between the sender and the receiver when the encoding operation is limited to the application of group represe…
Robust and efficient verification of graph states in blind measurement-based quantum computation
Zihao Li, Huangjun Zhu, Masahito Hayashi
Blind quantum computation (BQC) is a secure quantum computation method that protects the privacy of clients. Measurement-based quantum computation (MBQC) is a promising approach fo…
Prior Entanglement Exponentially Improves One-Server Quantum Private Information Retrieval for Quantum Messages
Seunghoan Song, Francois Le Gall, Masahito Hayashi
Quantum private information retrieval (QPIR) for quantum messages is a quantum communication task, in which a user retrieves one of the multiple quantum states from the server with…
Special functions in quantum phase estimation
Masahito Hayashi
This paper explains existing results for the application of special functions to phase estimation, which is a fundamental topic in quantum information. We focus on two special func…
Detection of Beyond-Quantum Non-locality based on Standard Local Quantum Observables
Hayato Arai, Baichu Yu, Masahito Hayashi
Device independent detections of quantum non-locality like Bell-CHSH inequality are important methods to detect quantum non-locality because the whole protocol can be implemented b…
