Charge based quantum computer without charge transfer

TL;DR

This paper proposes a charge-based quantum computer design that avoids charge transfer during operations, reducing unwanted entanglement and enabling high-speed computation around 1 picosecond per operation.

Contribution

It introduces a novel charge-based quantum computing approach that eliminates charge transfer, addressing entanglement issues caused by Coulomb forces.

Findings

Suppression of uncontrollable entanglement between qubits.

Feasibility of high-speed computation (~1 ps per operation).

Reduction of Coulomb force effects during calculations.

Abstract

A novel implementation of a charge based quantum computer is proposed. There is no charge transfer during calculation, therefore, uncontrollable entanglement between qubits due to long-range Coulomb forces is suppressed. High-speed computation with 1ps per an operation looks as feasible.
