Integrated solid circuits for quantum computing

Recent progress in nanometre structure and measurements is going to provide us with the freedom to domesticate fast correlations between atoms in an ensemble, manifesting them at macroscopic level. So we propose a prospective model of a solid state integrated circuit for quantum computation, based on our coherence generating dynamic dipole-dipole interaction theory. In this model, each qubit is a block consisting of an ensemble of quantum dots, and the energetics of which suggests stability up to room temperature. Moreover, a quantum controlled-controlled not (CCN) gate of the block structure is given as an essential unit. The spatiotemporal dynamics of the quantum entangled pure states, which is crucial for the execution of the quantum super-parallelism, is illustrated for the proposed quantum CCN gate.
