The Physics of quantum Locking
Ted
Talks video showing quantum locking
What is quantum locking?
Quantum locking is a phenomenon in which a magnetic field
partially penetrates a type II superconductor locking it
into place. To more completely understand this effect
an explanation of superconductors and the behavior of
magnetic fields is necessary.
