Abstract

In classical theory, phenomena are defined by the model of particles or waves, aiming to explain reality with certainty. In quantum theory, the phenomena are described by a quantum state |α, t⟩, which explains the reality with uncertainty. Although in quantum theory, the reality is probabilistic, the quantum state |α, t⟩ can be determined with certainty due to the unitarity principle. The technology needs deterministic phenomena, and then quantum technology must be constructed based on this fundamental quantum state. The critical point in quantum technology is to build the deterministic phenomena from the quan- tum state |α, t⟩: this is the main argument in the present article. The realization of quantum technology comprises three steps: constructing an appropriate quantum state, obtaining its time evolution, and detecting it deterministically.
