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

Abstract

SUMMARYRecent 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 ( 4 ) gate applying our RDDDI. Moreover, integration of the 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 shu ing circuit.

“…The QDs are also used in nanophotonics [76] because of their theoretically high quantum yield and have been suggested as implementations of qubits for quantum information processing [77]. The QD nanotechnology is one of the most promising candidates for use in solid-state quantum computation [87,88]. High-quality QDs are well suited for optical encoding [83,84] because of their broad excitation profiles and narrow emission spectra.…”

“…The new generations of QDs have far-reaching potential for the accurate investigations of intracellular processes at the single-molecule level, high-resolution cellular imaging, long-term in vivo observation of cell trafficking, tumor targeting, and diagnostics [85,86]. The QD nanotechnology is one of the most promising candidates for use in solid-state quantum computation [87,88]. It may also be noted that the QDs are being used in single electron transistors [89,90], photovoltaic devices [91, 92], photoelectrics [93], ultrafast all-optical switches and logic gates [94-97], organic dyes [98-100], and in other types of nanodevices.…”
