The
team behind the new technology has been tasked with creating an
impenetrable network for the Australian government, according to a
Australian Broadcasting Corporation report.
The technique pioneered by a team of scientists in Sydney, is called quantum cryptography.
"One
of the things you can do with the quantum computing is to expand the
data security capabilities a country has," said Morello University of
New South Wales.
Traditionally, cryptography involves three main parties - a sender, the recipient and the eavesdropper or hacker.
Hackers at present are able to intercept communications without the sender or recipient knowing, Morello added.
But
quantum cryptography will be able to prevent access by detecting
hackers and destroying or altering messages as hackers try to obtain
them.
"Anyone who attempts to eavesdrop the connection and essentially tap the data would destroy the data on the spot," he said.
The
problem however is actually in making the computer, he said adding that
to make a quantum chip a single phosphorous atom is introduced into a
regular silicon chip.
The atom's magnetic core - its nucleus is completely isolated the outside world because it so minute.
"What
we have shown is that we can write and read quantum information in the
magnetic orientation of the nucleus," said Morello.
To
give an idea of scale, a computer with 300 quantum bits is thought to
be able to contain a level of classical information equivalent tothe
elementary particles of the universe.
"What we
are reliant on at the moment is the fact that it's just too hard to
decrypt," said Vikram Sharma, the chief of QuintessenceLabs.
However he added that in future through thingsquantum computers these codes could be broken.
Cyber
security is high on government's agenda following the last month
reports on Chinese hackers allegedly gaining access to Australian
government systems.
The new quantum network will incorporate Capital Hill, the new ASIO building and governmental departments such as the Treasury.
"It
consists of fibre-optic links in the parliamentary triangle in Canberra
to transmit information in an absolutely secure way," said Morello.
