Spatiotemporal Dynamics of Quantum Computing Dipole-Dipole Block Systems

The stability of dynamic dipole-dipole interactions in a quantum dot array is estimated, and a novel solid state quantum CCN (controlled controlled not) gate having a block structure of quantum dot array is proposed. Quantum mechanical coherence is expected to be maintained, and both the bit error and the phase error are reduced by the ensemble effects in the block. The overall process of quantum computing is presented schematically, showing four main steps. The spatiotemporal dynamics of the quantum entangled pure state, which is the kernel of the quantum super-parallel computation, is also illustrated for the proposed quantum CCN gate.
