Australian
scientists developing a prototype quantum hard drive say they have
improved storage time by a factor of more than 100. Manjin Zhong, from
the Research School of Physics and Engineering (RSPE) at The Australian
National University (ANU), said: "Quantum states are very fragile and
normally collapse in milliseconds. Our storage times have the potential
to revolutionise the transmission of quantum
information."

normally collapse in milliseconds. Our storage times have the potential
to revolutionise the transmission of quantum
information."
The
team of physicists at ANU and the University of Otago stored
information for six hours by writing a quantum state onto the nuclear
spin of a europium atom using laser light, then subjecting the crystal
to a combination of a fixed and oscillating magnetic fields to preserve
the information. "The two fields isolate the europium spins and prevent
the quantum information leaking away," explained Dr Jevon Longdell of
the University of Otago.
Zhong added: "We can now imagine storing entangled light in separate
crystals and then transporting them to different parts of the network
thousands of kilometres apart. So, we are thinking of our crystals as
portable optical hard drives for quantum entanglement."
This will allow the group to undertake fundamental tests of quantum
mechanics. "We have never before had the possibility to explore quantum
entanglement over such long distances," said associate Professor Matthew
Sellars. "We should always be looking to test whether our theories
match up with reality. Maybe in this new regime our theory of quantum
mechanics breaks."
