The University of Adelaide\u2019s newest Ramsay Fellow, Dr James Quach, will harness the unique properties of quantum mechanics with the aim of building the world\u2019s first quantum battery, a new super battery with the potential for instantaneous charging.<\/p>\n

Once built, the quantum battery could replace conventional batteries used in small electronic devices. Eventually it is hoped larger quantum batteries could provide opportunities for the renewable energy sector.<\/p>\n

Dr Quach, who is an expert in quantum physics, has joined the University of Adelaide\u2019s School of Physical Sciences<\/a> for four years under a Ramsay Fellowship. He will be working within the Precision Measurement Group in the University\u2019s Institute for Photonics & Advanced Sensing<\/a> (IPAS).<\/p>\n

The Ramsay Fellowship was established in 2008 with a bequest by the Ramsay family, founders of the Kiwi Polish Company (later Kiwi International), to reduce the brain drain from our shores and advance scientific research.<\/p>\n

Dr Quach says that unlike ordinary batteries, which take the same amount of time to charge no matter how many you have, the theory is that quantum batteries would charge faster the more you have of them.<\/p>\n

\u201cIf one quantum battery takes one hour to charge, then two would take 30 minutes, three would take 20 minutes, and so on. If you had 10 thousand batteries, they would all charge in less than a second,\u201d says Dr Quach.<\/p>\n

Although it seems counterintuitive, this is possible thanks to a feature of quantum mechanics known as entanglement.<\/p>\n

\u201cQuantum mechanics deals with interactions at the very smallest of scales, at the levels of atoms and molecules \u2013 at this level you get very special properties that violate the conventional laws of physics,\u201d says Dr Quach.<\/p>\n

\u201cOne of those properties is \u2018entanglement\u2019. When two objects are entangled it means that their individual properties are always shared \u2013 they somehow lose their sense of individuality.<\/p>\n

\u201cIt\u2019s because of entanglement that it becomes possible to speed up the battery charging process,\u201d he says.<\/p>\n

The idea for a quantum battery was first discussed in a 2013 research paper. Since then there have been other papers on the subject, but Dr Quach says he will \u201ctake the theory from the blackboard to the lab\u201d.<\/p>\n

\u201cEntanglement is incredibly delicate, it requires very specific conditions \u2013 low temperatures and an isolated system \u2013 and when those conditions change the entanglement disappears,\u201d he says.<\/p>\n

\u201cWith the support of the academic community in Adelaide, interstate and globally, I aim to extend the theory of the quantum battery, construct a lab conducive to the conditions needed for entanglement, and then build the first quantum battery.\u201d<\/p>\n

This revolutionary battery could be used in small electronic devices such as a watch, phone, iPad or computer or any other product that relies on stored energy.<\/p>\n

\u201cThe long-term aim is to scale up, to build bigger batteries which will support renewable energy technologies by making it possible for continuous energy supply no matter the weather conditions \u2013 rain, hail or shine,\u201d Dr Quach says.<\/p>\n

The Ramsay Fellowships are open to Australian citizens with a PhD or equivalent qualification in the natural sciences, with preference given to applicants aged 35 years and under.<\/p>\n
