A New Approach to Quantum Computing Multi-Qubit Generation and Development of Quantum Computing Platform with Magnetic Resonance Imaging Techniques

Abstract

Increased interest in quantum computing has resulted in various proposals for generating quantum bits or qubits. Superconducting qubits of the Josephson junction are the most widely accepted and currently used, while ion-trap and similar molecule-based qubits have been proposed more recently. In these methods, each qubit is generated individually with great effort. Here, we proposed a new technique using magnetic resonance imaging (MRI) to simultaneously generate multiple qubits and provide a complete qubit platform for quantum computing. Central to this method is the “gradient” concept with multiple radiofrequency coils, one for all qubits and others for individual qubits with each small Q-coil. Another key concept is the time-encoded probability amplitude technique, using individual Q-coils with the spin-echo series in each qubit incorporating readout gating for time-encoding. Our newly proposed MRI-based qubits are well-suited to currently available electronics, superconducting and semiconductor technologies, and nuclear magnetic resonance and MRI physics and technology.
