"MRAM, based on quantum magnetic materials, offer 1,000X memory device performance, but difficult to read from... antiferromagnets without magnetization can read at very high speeds... grow crystals in a vacuum, in incredibly fine layers using two processes called molecular beam epitaxy and magnetron sputtering... exploit quantum entanglement... useful or even essential to build a bridge between the current paradigm of electronic computing and the emerging field of quantum computers"
