In the law of Patents, the presence of two pending applications, or an existing patent and a pending application that encompass an identical invention or discovery.

When interference exists, the Patent and Trademark Office conducts an investigation to ascertain the priority of invention between the conflicting applications, or the application and the patent. A patent is customarily granted to the earlier invention.

This observation turns out to be the first quantum algorithm, known as the Deutseh-Josza algorithm (Deutsch & Jozsa, 1992), where physical principles such as quantum interference and quantum entanglement were made evident as a powerful computational resource.
He described the device, which monitors fetal development, as a ,super conducting quantum interference device" expensive liquid helium to create extreme cold necessary for its operation.
Scurrying through the back alleys of a decadent underground like an oiled rat, Lenny Nero (Ralph Fiennes) peddles other people's realities preserved on MiniDiscs through the magic of SQUID (Superconducting Quantum Interference Device), a technology that records and plays back human experience "straight from the cerebral cortex," allowing the user to be anyone this time around, for a price.
The technology uses Superconducting Quantum Interference Devices (SQUIDs) and non-toxic iron oxide nanoparticles to find and measure cancer and to develop new biomarkers for targeting specific cancers.
The Department of Defense contract announcement said, the companies will provide systems acquisition support, systems engineering, project management, basic research, development, evaluation and implementation of cryogenic radio frequency systems, and advanced cryogenic core digital and quantum memory technologies, exploiting superconducting quantum interference device, tactical signals intelligence systems, and other military platforms.
Regarding your recent article, "Real-time single-molecule imaging of quantum interference," I have performed calculations on your data that do not make sense to me.
The obtained results might be explained as follows: The oscillatory behavior of the conductance is due to spin-sensitive quantum interference effects caused by the difference in the Aharonov-Casher phase accumulated by the opposite spin states.
Because the energy of the fields is so much smaller than that used by traditional MRI, the relaxation time is obtained with extremely sensitive magnetic-field detectors called superconducting quantum interference devices, or SQUIDs, which are cooled to liquid-helium temperatures.
In this research paper, the scientists show that a magnetic field-pulsed microwave transmission line containing an array of superconducting quantum interference devices, or SQUIDs, not only reproduces physics analogous to that of a radiating black hole, but does so in a system where the high energy and quantum mechanical properties are well understood and can be directly controlled in the laboratory.
