Solid state coherent quantum dot system for quantum computing and quantum transmission

摘要

Recent progress in nano-metre structure and measurements is capable of providing us with the freedom to harness fast and seemingly weak correlations between atoms in an ensemble, manifesting them at macroscopic level. So we have investigated a prospective model of solid state integrated circuits for quantum computation, based on our coherence retentive resonance dynamic dipole-dipole interaction (RDDDI) 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. Here, we propose a qubit swap (Π_4) gate applying our RDDDI. Moreover, integration of the Π_4 gate is proposed to form quantum circuits that can transfer a qubit state to any position within them, realizing bit reversal permutation circuits with even and odd bits, and a shuffling circuit.
