  Explosive increase of interest in quantum computing has resulted in various
proposals for generation of quantum bits or qubits, the basic quantum computing
unit. The superconducting qubits of Josephson Junction are the most widely
accepted and currently used, while the Ion-trap and a 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)-based qubit generation, by which
multiple qubits can be generated. Simultaneously this provides a complete qubit
platform for quantum computing. Central to the proposed method is the
simultaneous generation of multiple qubits using the 'gradient' concept
together 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 (TEPA) technique, using individual Q-coils
together with the spin-echo series in each qubit incorporating readout gating
for time-encoding. This MRI-based qubit-generation and qubit-encoding technique
allowed us to develop an entirely new class of quantum computing platform. Our
newly proposed MRI-based qubits are well-suited to currently available
electronics, superconducting and semiconductor technologies, as well as nuclear
magnetic resonance and MRI physics and technology.
