Abstract
A qubit device includes a crystal immobilized on a substrate and in contact with electrodes. The crystal exhibits a charge pair symmetry and with an electron current moving clockwise, counter clockwise, or both. The current in can be placed in a state of superposition wherein the current is unknown until it is measured, and the direction of the current is measured to produce a binary output corresponding to a logical zero or a logical one. A state of the qubit device is monitored by measuring a voltage, a current, or a magnetic field and assigning a superposition or base state depending on a threshold value.
