As in a superconducting electrode, the phase and the charge are conjugate variables. There exist three families of superconducting qubits, depending on whether the charge, the phase, or neither of the two are good quantum numbers. These are respectively termed charge qubits, flux qubits, and hybrid qubits. ==Theory== Unlike many other physical implementations of a qubit which involve exclusively two-level systems (such as nuclear spin and photon polarization), the integrated quantum circuit involved in a superconducting qubit is a multi-level system, of which only the first two levels are used as the computational basis. A basic requirement for such an implementation is that the energy levels are not uniformly spaced, so that photons of a particular frequency which cause transition between the 0 and 1 levels do not cause transitions from the first level to the higher levels as well. For electronic signals to be carried from one part of the circuit to another without energy loss and hence decoherence, the system also needs to be non-dissipative, i.e., the metallic parts involved should have zero resistance. These circuits currently need to be operated at very low temperatures so that, 1) superconductivity is realized, and 2) thermal fluctuations do not cause transitions between energy levels. 抄文引用元・出典: フリー百科事典『 ウィキペディア（Wikipedia）』 ■ウィキペディアで「Superconducting quantum computing」の詳細全文を読む スポンサード リンク 翻訳と辞書 : 翻訳のためのインターネットリソース Copyright(C) kotoba.ne.jp 1997-2016.
