IBM has made a functioning quantum processor available to the public over the internet.

Quantum computing is widely seen as an evolution of computer technology, which may allow for much faster calculations than today's machines.

The technology is still in its infancy, but one expert said it was a "small step" towards a useful quantum computer.

IBM said it hoped to see processors up to 20 times larger in the next decade.

Traditional computers process all their information using bits - information stored in tiny transistors that can either be on or off - interpreted as values of one and zero.

Quantum computing instead takes advantage of a mechanic called superpositioning that allows quantum bits - or "qubits" - to have values of one, zero, or both at the same time.

Researchers believe this core difference will eventually lead to powerful devices with processing power that will exceed the limits of classic computers.

IBM's quantum processor is located in its TJ Watson Research Centre in New York. Quantum processors are notoriously sensitive, so it is being kept at supercooled temperatures in a cryogenic refrigerator.

It has just five qubits that can be manipulated, but the company expects processors of 50-100 qubits to emerge within the next decade. General-purpose machines, which IBM calls "universal" quantum computers, will eventually use more than 100,000 qubits.
