Australians design new Qubit

Australia researchers have designed a new type of qubit which is close to creating a real, full-size quantum computer, ScienceAlert reported.

From the article: “If they’re too close, or too far apart, the ‘entanglement’ between quantum bits – which is what makes quantum computers so special – doesn’t occur,” says the researcher who came up with the new qubit, Guilherme Tosi, from the University of New South Wales in Australia.

With traditional Qubits, the distance causes machines to grow large. For smaller machines (tens or dozens of qubits) this is not a problem. But the goal is to create machines with thousands of qubits – so the machines would grow unweildy.

The Australians have created a quantum “flip-flop” that is triggered by electrons rather than magnetism. Magnets take up more space and electronic quantum entanglement can be maintained over a longer distance.

The electronic quantum flip-flop is still a hypothetical design so there are no extant devices. Research continues.
