There will be a quantum computer with over 100 qubits of processing capability sold either as a hardware system or whose use is made available as a commercial service by Dec 31, 2010
Since some money is on the line and potentially more money, I have decided to give my prediction some cushion. I am pretty sure that Dwave Systems will come through but just in case they have problems... I have left some time for ion traps and electron bubbles to make it as well.
I think Dwave Systems should come through with at least 64 qubits in 2007 and 128 qubits or better in 2008.
At least, 155 Computer Science IEEE fellows apparently have said that this prediction will be wrong
