Quantum Computer Systems? New Flip-Flop Qubit Design Could Usher Them In Quickly

Researchers in Australia have discovered a brand new technique to construct quantum computer systems which they are saying would make them dramatically simpler and cheaper to provide at scale.

Quantum computer systems promise to harness the unusual capacity of subatomic particles to exist in a couple of state at a time to unravel issues which can be too advanced or time-consuming for current computer systems.

Google, IBM and different know-how firms are all creating quantum computer systems, utilizing a spread of approaches.

The crew from the College of New South Wales say they’ve invented a brand new chip design primarily based on a brand new sort of quantum bit, the fundamental unit of knowledge in a quantum laptop, often called a qubit.

The brand new design would permit for a silicon quantum processor to beat two limitations of current designs: the necessity for atoms to be positioned exactly, and permitting them to be positioned additional aside and nonetheless be coupled.

Crucially, says undertaking chief Andrea Mello, this so-called “flip-flop qubit” means the chips could be produced utilizing the identical machine know-how as current laptop chips.

“This makes the constructing of a quantum laptop way more possible, since it’s primarily based on the identical manufacturing know-how as right this moment’s laptop business,” Mello mentioned.

That will permit chips for quantum computer systems to be mass-manufactured, a aim that has up to now eluded different researchers.

IBM’s quantum laptop in the USA has 16 qubits, that means it might probably solely carry out fundamental calculations. Google’s laptop has 9 qubits.

A desktop laptop runs at gigaflops. The world’s quickest supercomputer, China’s Sunway TaihuLight, runs at 93 petaflops, however depends on 10 million processing cores and makes use of large quantities of power.

In concept, even a small 30-qubit common quantum laptop may run on the equal of a basic laptop working at 10 teraflops.

The researchers’ paper will probably be revealed in Nature Communications.

Laszlo Kish, a professor at Texas A&M College, mentioned it was too early to say if the analysis was a breakthrough “however it might be a step within the correct route” in fixing a number of the key obstacles to quantum computing.

The college has arrange an organization, Silicon Quantum Computing Pty Ltd, with investments from Telstra, Australia’s Commonwealth Financial institution and the Australian and New South Wales governments.

The A$83 million firm plans to construct a 10-qubit prototype silicon quantum built-in circuit – step one in constructing the world’s first quantum laptop in silicon – by 2022.
