Efficient chip enables low-power devices to run today's toughest quantum encryption schemes. MIT researchers have developed a novel cryptography circuit that can be used to protect low-power "internet of things" (IoT) devices in the coming age of quantum computing. Quantum computers can in principle execute calculations that today are practically impossible for classical computers. Bringing quantum computers online and to market could one day enable advances in medical research, drug discovery, and other applications. But there's a catch: If hackers also have access to quantum computers, they could potentially break through the powerful encryption schemes that currently protect data exchanged between devices. Today's most promising quantum-resistant encryption scheme is called "lattice-based cryptography," which hides information in extremely complicated mathematical structures. To date, no known quantum algorithm can break through its defenses.
