Distance and time limit on quantum control under decoherence (本文)
幸平 小林
To realize quantum information technologies, a technique of quantum control for preparing a desired quantum state used for an information resource plays an important role.For example, the measurement-based feedback control is a powerful method and many notable experiments have been demonstrated in superconducting qubit.However, in spite of the large impacts and development of those technologies, decoherence, which is the loss of quantum properties, is the fundamental and biggest obstacle.Due to it, the quantum state collapses to the classical state and the actual control performance is sometimes far away from the ideal one.Therefore, in considering the practical quantum
