The present disclosure relates to Superfluid QUantum Interference Devices (SQUIDs) that measure phase differences existing in quasi-particles or matter-wave systems, and the related techniques for their use at room-temperatures. These Bose-Einstein Condensation interferometry techniques include quantum scale metrology devices such as quasi-particle based linear accelerometers, gyroscopes, and Inertial Measurement Units that incorporate such interferometers. In the presence of additive white Gaussian noise, estimates are made for the Bias Instability, Angle Random Walk, and Velocity Random Walk of the device for purposes of quantum inertial sensing. Moreover, this disclosure relates to SQUIDs based on charged quasi-particles that can, in turn, be used to construct quantum computing elements such as quantum transistors, and quasi-particle circuits at room-temperatures. These quasi-particle circuits can be used to build analogs of electronic circuit elements, and offer an alternative to traditional electronics. Using a quasi-particle circuit, hysteresis can be achieved and controlled to build these new devices.
