Researchers in Australia have developed a new kind of cryogenic quantum computer chip that works close to the theoretically coldest temperature in the universe and could cause a new technological revolution.
The system, the gooseberry, runs 40 times colder than the depth of the temperature – an increase of 20 times more than is possible today with quantum computers.
Very complex mathematical equations that take traditional supercomputers hundreds, or not thousands of years to calculate, a quantum computer can take a matter of seconds to complete.
“It’s going to be transformation in the next few years,” says Andrew White, director of the ARC Center of Excellence for Engineered Quantum Systems.

Traditional computers use ‘pieces’ of information. A bit by nature is binary, on or off, black or white, yes or no. Its equivalent in quantum computation is a quit, which uses the strange, shaky world of quantum mechanics to create a “Superposition” of two separate states simultaneously, thus greatly increasing computational power.
Most modern day quantum computers use a few dozen kwbits. But with these new cryogenetic chips, machines can do calculations with thousands if not millions of cubic meters or more, achieving unimaginable levels of processing power to date.
Qubits require extremely low temperatures to operate efficiently, and the electrical wiring used to connect them has often interrupted operation by overheating. The Gooseberry system uses a highly paired two-wire system to connect it to a secondary core in a separate compartment.
The system can do this because it works at “Millikelvin” temperatures, which are fractionally above absolute zero at 0.1 kelvin, or -459.49 degrees Fahrenheit (273.05 degrees Celsius). The absolute zero itself is -273.15 degrees Celsius.

The breakthrough indicates what scientists from the University of Sydney and Microsoft Corporation call “The next chapter in quantum technology,” and can lead to historical and revolutionary advances in fields as diverse as cryptography, medicine, finance, artificial intelligence and logistics.
The researchers make the staggering assertion that quantum computers are currently in a similar stage of development as traditional computers were in the 1940s.
While their current prototype took four years to develop, the scientists plan to continue plowing and “Realize quantum technology on an industrial scale.”
