A SQUID (for superconducting quantum interference device) is a very sensitive magnetometer used to measure extremely subtle magnetic fields, based on superconducting loops containing Josephson junctions. SQUIDS are the basis for quantum computing. SQUID is an object that was “predicted historically to demonstrate weird quantum phenomenon at macroscopic scales”. SQUID is a measuring device. There are parallel universes or levels of existence in the universe so if this is correct can a SQUID measure what is in this other existence? It was at the Ford Motor Co. where the SQUID was invented. Ford’s SQUID Team: The researchers who invented the SQUID were John Lambe, James Zimmerman, Arnold Silver, Robert Jaklevic, and James Mercereau. In the video clip below of an interview with D-Wave’s Eric Ladizinsky, Ladizinsky recalls how he worked with Arnold Silver.
SQUIDs are sensitive enough to measure fields as low as 5 aT (5×10−18 T) within a few days of averaged measurements. Their noise levels are as low as 3 fT·Hz-½. For comparison, a typical refrigerator magnet produces 0.01 teslas (10−2 T), and some processes in animals produce very small magnetic fields between 10−9 T and 10−6 T. Recently invented SERF atomic magnetometers are potentially more sensitive and do not require cryogenic refrigeration but are orders of magnitude larger in size (~1 cm3) and must be operated in a near-zero magnetic field.
