Limitations of Quantum Measurements and Operations of Scattering Type under the Energy Conservation Law
Ryota Katsube, Masanao Ozawa, Masahiro Hotta
It is important to improve the accuracy of quantum measurements and operations both in engineering and fundamental physics. It is known, however, that the achievable accuracy of me…
Deep Learning Metric Detectors in General Relativity
Ryota Katsube, Wai-Hong Tam, Masahiro Hotta +1
We consider conceptual issues of deep learning (DL) for metric detectors using test particle geodesics in curved spacetimes. Advantages of DL metric detectors are emphasized from a…
A Fundamental Upper Bound for Signal to Noise Ratio of Quantum Detectors
Ryota Katsube, Masahiro Hotta, Koji Yamaguchi
Quantum fluctuations yield inevitable noises in quantum detection. We derive an upper bound of signal to noise ratio for arbitrary quantum detection described by trace-class operat…
