If you've been dying to run some math on a dinky toy quantum computer, IBM may have something for you

Re: How did they predict the development thing?

I agree with your assessment. FTA:

"The qubits that make it so powerful lose their properties within 100 microseconds – and that time falls off significantly with any introduction of vibrations or temperature change."

The more important fact is that each additional qubit increases the instability exponentially, and there seems no way around this due to the quantum nature of reality. This is why IBM's quantum computer has only 20 qubits; They've approached a hard, built-in limit, not unlike the speed of light.

I see it as a good thing. It preserves the utility of public key encryption, and who knows what else? I for one would not relish going back to the days of physical couriers transporting crypto keys all over the planet, with briefcases handcuffed to their wrists. Online retailing is just too convenient!
