Aussieâs âabsolute zeroâ quantum computing breakthrough Save Share A team of scientists at the University of Sydney says it has overcome one of the biggest problems standing in the way of anyone building a quantum computer that can actually do something useful: how do you control a quantum computer operating at temperatures close to absolute zero, without running so many wires to it that you warm it up and render it useless? Nature, the team announced it has invented a pair of computer chips nicknamed âGooseberryâ, which could operate inside the icy cold refrigerators required by most quantum computer designs, and still provide an interface to the outside world without significantly raising the temperature inside the fridge.
