The Future of Quantum Computing

More recently the issues of the technology required to implement quantum computing on a useful level drive innovations on a many different frontiers.   With the complexity and fragility of the system involved however, quantum computing is most definitely still in the initial stages.  Decoherence of the systems have forced a great deal of focus into quantum error correction.  The requirements for controlled singular photons has led to some impressive advances, but yet again the technological barrier has not progressed so far as to allow convenient usage.

At every stage of production the quantum computer has a great deal of work that needs to be done, and each step must be painstakingly analyzed and protected from the harsh environment that surrounds the extremely delicate system.

Even once such systems can be produced for small experiments to confirm the effects we seek, it will be quite some time before the production techniques and applications are so well refined as to allow for mass production or even a working prototype.

More importantly, there does not seem to be any choice but to move to these systems. As our computers become more and more compact, the effects of quantum events are going to make themselves first known and then become overwhelming. The solutions appear to be evolution or stagnation.
