Non-unitary Process and Quantum Communication
Riuji Mochizuki
The no-communication theorem states that the observation of a subsystem of an entangled state does not affect another subsystem. Nevertheless, this theorem is based on the assumpti…
Quantum communication by means of collapse of the wave function
Riuji Mochizuki
We show that quantum communication by means of collapse of the wave function is possible. In this study, quantum communication does not mean quantum teleportation or quantum crypto…
Decoherence as an inherent characteristic of quantum mechanics
Riuji Mochizuki
We show that it is possible to explain the quantum measurement process within the framework of quantum mechanics without any additional postulates. The key concept of the theory is…
Understanding weak values without new probability theory
Riuji Mochizuki
The physical meaning of weak values and measurements can be completely understood with Born rule and the general probability theory. It is known that the weak value of an observabl…
Weak value as an indicator of back-action
Riuji Mochizuki
In this study we critically examine some important papers on weak measurement and weak values. We find some insufficiency and mistakes in these papers, and we demonstrate that the…
Quantum logic and weak values
Riuji Mochizuki
In this study, we study weak values from a quantum-logical viewpoint. In addition, we examine the validity of the counterfactual statements of Hardy's paradox, which are based on w…
