Can quantum computers appear in the near future?

Answer 1

they already exist, it's just that the error rate is still too high. And there are not very many quantum algorithms yet. For home use in the near future are unlikely to appear.
p.s. Why would you? It is necessary to pick up keys for RSA quickly?

Answer 2

They've been around since 2007. Only sense from them? Will be purely scientific or enterprise. With its software and hardware.

Answer 3

Still not soon. Although research is ongoing. Now they are still talking about plasmonics, which will have to replace electronics, but I think it will be in 50 years, not earlier.
Graphene will most likely be used in the short term. Intel hits the limit of silicon - 7 nanometers, and then there are several development options

Answer 4

Надеюсь, что оптические появятся раньше. От них пользы больше будет.
