- Today’s computer chips get cheaper and faster as their features get smaller, but quantum mechanics says that at tiny enough scales, particles sail through solids, short-circuiting the chip’s innards.
- Rather than scale devices down, quantum technologies employ the unusual behaviours of single atoms and particles and scale them up.
- Even as high-security quantum networks are being developed, a countervailing worry is that quantum computers will eventually render obsolete today’s cryptographic techniques, which are based on hard mathematical problems.
- Long before that happens, however, smaller quantum computers will make other contributions in industries from energy and logistics to drug design and finance.
- Even simple quantum computers should be able to tackle classes of problems that choke conventional machines, such as optimising trading strategies or plucking promising drug candidates from scientific literature.
