Evaluation of Impression Difference of a Domestic Mobile Manipulator with Autonomous and/or Remote Control in Fetch-and-Carry Tasks
Takashi Yamamoto, Hiroaki Yaguchi, Shohei Kato +1
A single service robot can present two distinct agencies: its onboard autonomy and an operator-mediated agency, yet users experience them through one physical body. We formalize th…
Unambiguous discrimination of the change point for quantum channels
Kenji Nakahira
Identifying the precise moment when a quantum channel undergoes a change is a fundamental problem in quantum information theory. We study how accurately one can determine the time…
Improving quantum channel discrimination with resourceful states
Kenji Nakahira
One of the key issues in quantum discrimination problems is understanding the extent of the advantages in discrimination performance when using resource states compared to resource…
Symmetric silicon microring resonator optical crossbar array for accelerated inference and training in deep learning
Rui Tang, Shuhei Ohno, Ken Tanizawa +5
Photonic integrated circuits are emerging as a promising platform for accelerating matrix multiplications in deep learning, leveraging the inherent parallel nature of light. Althou…
Identifying quantum change points for Hamiltonians
Kenji Nakahira
The identification of environmental changes is crucial in many fields. The present research is aimed at investigating the optimal performance for detecting change points in a quant…
Generalized quantum process discrimination problems
Kenji Nakahira, Kentaro Kato
We study a broad class of quantum process discrimination problems that can handle many optimization strategies such as the Bayes, Neyman-Pearson, and unambiguous strategies, where…
