Accurate Atom Qubits Attain Major Quantum Computing Goal

The exclusive Australian method of making quantum bits from exactly placed separate atoms in silicon is getting major awards, with scientists from UNSW Sydney displaying for the first time that they can make 2 of these qubits atom “communicate” with each other. The team spearheaded by Michelle Simmons, Professor at UNSW and Director of the CQC2T (Centre of Excellence for Quantum Computation and Communication Technology), is the only team all over the world that has the capability of seeing in the solid state the exact location of their qubits.

Simmons’ group makes the atom qubits by encapsulating and accurately positioning separate phosphorus atoms inside a silicon processor. Data is amassed on a single phosphorus electron’s quantum spin. The group’s latest advancement, which is the first surveillance of controllable communications between two qubits, is posted in the Nature Communications journal. It follows 2 other latest advancements employing this exceptional method to build a quantum device.

By optimizing their process of nano manufacturing, Simmons’ group has also lately produced quantum circuitry with the least witnessed electrical noise of any semiconductor gadget. And they have made an electron rotate a qubit with the best lifetime ever clocked in a nano-electric gadget—30 Seconds.

“The joint outcomes from these 3 research papers verify the tremendously promising prospects for making multi-qubit systems employing our atom qubits,” claims Simmons to the media in an interview. Simmons, who in January was awarded “2018 Australian of the Year” for her ground-breaking quantum computing study, claims that her team’s innovative work is encouraged by the works of late physicist Richard Feynman.

“Feynman claimed, ‘What I cannot make, I do not recognize. We are acting out that policy systematically, atom by atom from the scratch,” claims Simmons. “We are the only team all over the world who can really look where our qubits are present,” she added.
