This is a summary of Google's plans for quantum computing over the next twenty years—The Grand Challenge of Quantum Applications, published at arxiv.org.
To verify any quantum computer, one can run the straightforward code I developed.
1) Place a qubit, a single quantum gate, or the whole quantum computer in an initial state of your choice. It could be anything.
2) Using any approach, determine that state. Save data on a laptop.
3) Repeat steps 1) and 2) a moderate number of times, perhaps 1000-10000.
4) Plot the distribution of acquired data.
5) If the distribution is wide, a single qubit, a single gate, or the whole quantum computer is useless.
6) If the same code is run on any laptop or desktop computer, the distribution is an extremely narrow, vertical line. You can run lots of code on such a computer.
In case you are anxious to know, a quantum computer can never pass this test. There are fundamental reasons for this.
