IBM will build and sell commercial 50-qubit universal quantum computers, dubbed IBM Q, "in the next few years." No word on pricing just yet, but I wouldn't expect much change from $15 million
vaporware. The technology is not there yet. Building such a computer will require technological breakthroughs that cannot be foreseen or performed to order.
but fortunately IBM also has news there: the company's quantum simulator can now simulate up to 20 qubits.
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.
