We experimentally test the error-disturbance uncertainty relation (EDR) in generalized, strength-variable
measurement of a single photon polarization qubit, making use of weak measurement that keeps the initial
signal state practically unchanged.W...

It is one of long-standing open problems in the field across physics and philosophy to give a realistic interpretation for values of quantum observables. In this research we proposed a new approach to this problem based on quantum set theory. We ...

The problem of realistic interpretation of quantum theory has produced several paradoxes and remains an important open problem in foundations of quantum theory. In this study we introduced methods of foundations of mathematics into this problem, a...
1.Heisenberg's uncertainty principle, which gives the trade-off between measurement noise and disturbance, has been reconsidered. Its limitation of the validity has been clarified and the universally valid generalization (universal uncertainty pri...
The following results have been obtained on mathematical foundations on quantum Turing machine and quantumcircuits: (1) Local transition functions of quantum Turing machines (QTM) are generally characterized including multitape cases. (2) The noti...
This is an interdisciplinary research including foundations of mathematics, applied analysis, mathematical physics, and quantum mechanics. The representation theory of hyperfinite Heisenberg groups was instituted by Ojima and Ozawa in 1992 in orde...
