Quantum computing in the Cloud?
02/02/2012
By using the inherent uncertainties in quantum physics to carry out fast, complex computations quantum computing is set to provide high-speed, high-security technology compatible with the "cloud computing".
A report in Science highlighted how quantum computing can be extended to "cloud" services like Google Docs without compromising security.
Quantum computing is now being talked about as possibly the most powerful successor to traditional computing.
One of quantum mechanics most interesting features is that objects can exist in more than one state at the same time and yet these objects can still be linked together. It is this phenomenon that allows quantum computing to perform calculations incredibly quickly.
Quantum computing also uses cryptography, to encode information. This delicate process uses particles of light called photons - and the information cannot be read without the photons being destroyed. Using this method a very high level of cloud computing security could be maintained.
These are however, early days and quantum computing is currently limited to simple calculations with quantum cryptography still very much in laboratory testing.
How long until we start to see the benefits of quantum technology in the cloud is hard to say.
