I believe that the future of computers is quantum. Maybe not the whole future of computers, but a fascinating and important part of it.
I also believe that the future of quantum physics is quantum computers, because QCs will test quantum mechanics by stretching it to its breaking point. Quantum Mechanics is now almost a century old, and it has explained for us, quantitatively, thousands of phenomena. QCs will bring quantum mechanics to the masses like ham radio brought electronics and PCs brought computer programming to the masses.
QCs are a new physics frontier, a new West, and it’s a frontier that promises a wondrous device at the end of the journey, unlike, for example, string theory, which doesn’t promise any new tabletop devices. (However, connections between quantum computation and its offshoot, quantum information theory, on the one hand, and string theory on the other, have been and continue to be discovered.)
The following phrase became popular in the USA in the mid 1800’s: “Go West young man, and grow up with the country”
Nowadays, that great advice might be updated to: “Go Quantum, Young Person”
(notice that the shadows in this photo indicate that the astronaut is traveling towards the West):
The following YouTube Video shows a famous scene from the 1967 film “The Graduate”. In the scene, a shockingly young Dustin Hoffman, freshly graduated from college, is given the following advise by a much older man, “One word…Plastics.”
Nowadays, that old man should instead be saying “One word…Quantum”
