The OP asked about
NANO computing, not quantum computing.
Nanocomputer refers to a computer smaller than the microcomputer, which is smaller than the minicomputer. ... The term nanocomputer is increasingly used to refer to general computing devices of size comparable to a credit card.
Nano computers will enable us to put a bitcoin node on a card or on a USB stick.
Would we then be able to utilize the power of multiples of such devices? Imagine a mining pool ran off nano devices, or some type of nano raid array if possible.
