The technology is not there yet. Building such a computer will require
technological breakthroughs that cannot be foreseen or performed to order.

Similating 20 qubits requires O(2^20) storage and O(2^20) computation
time on a classical computer. I could simulate a 20 qubit computer on
my desktop
Hell, I could simulate a 32 qubit computer on my desktop. 50 qubits,
however .... I would be impressed.
