==Problems==

There are still numerous problems with quantum computing from a practical standpoint.  While the science behind it works, it is currently very cost-prohibitive to make a quantum computer.  Additionally, the processor must be kept very cold (at least .001 degrees Kelvin) which requires a significant amount of cooling apparatus and refrigerant (liquefied gases). As it runs, it also heats up, meaning that breaks are typically required to allow the processor to cool down. Rather than this being a device to sit on a desk, this is a device which takes up a very large room.
