A recent study revealed that the basic underlying mechanisms of quantum computing - a potentially ultrafast method of computer processing - are viable. A fully operational quantum computer would be nothing short of revolutionary; with this in mind, Google appears to have officially declared that its D-Wave system is able to use quantum physics to calculate complex mathematical algorithms. Some outside experts have expressed doubt, however.
Conventional computers communicate and store information and data in bits using binary language. Quantum computing
uses qubits, which take advantage of the fact that particles can exist in multiple states at the same time - this is known as superpositioning. If a particle exists in two states simultaneously, these can be combined to produce a third state. Therefore, if one state is represented by a 1, and the other is the 0, the superpositioned state can represent a combination of the two.
