From Sam Edge, Ringwood, Hampshire, UK
The same sentiment that “you will probably never own a personal quantum computer” computers in the 1950s, 60s and 70s. Current quantum computers are still nothing but proofs of concept. But once commercially viable and useful ones become available to buy, the pressure will be on to make them more powerful and cheaper. This may spur innovation in miniaturising confinement and cooling systems and in room-temperature superconductors, which may eventually lead to devices the size of today’s gaming PCs and perhaps eventually even smaller. At that point, why wouldn’t we all have one at home(Leader, 15 February)?
