Woman leading race to build world's first quantum computer
Sydney, May 11: A team of Australian scientists has made great strides towards building the world's first quantum computer, using mostly standard silicon technology. The team is led by 50-year-old Michelle Simmons, a mother of three.
It is believed that the quantum computing technology could help address major global challenges like climate change and understanding complex diseases such as cancer.
"We're hoping to actually build computers here in Australia that will be able to do calculations in real time that would otherwise take thousands of years," Simmons, Professor at University of New South Wales (UNSW) Sydney, said in statement.
The winner of the coveted 2018 Australian of the Year award leads a team of more than 200 researchers at eight universities across the country developing a cache of quantum computing technologies.
In the quantum world, every time a quantum bit (qubit) is added, the amount of information is doubled.
"If I can get to 300 qubits, there's a prediction that it's more than all the atoms in the universe working together as a calculation," Simmons said, adding that her team is the only one in the world that can manipulate individual atoms to make atomically precise electronic devices.
The progress made by the UNSW research programme has been possible to a great extent due to its focus on silicon, which is industrially-compatible and forms the basis for the existing computer and electronics industry.
The team focuses on making qubits out of single atoms of phosphorus or quantum dots in silicon.
In 2017, the British-born Simmons established Australia's first quantum computing company, Silicon Quantum Computing (SQC), to develop, by 2022, a 10-qubit prototype silicon quantum integrated circuit -- the first step in building the world's first quantum computer in silicon.
The company is owned by the Australian Government, the Commonwealth Bank of Australia (CBA), Australian telecommunication Telstra, the UNSW and the New South Wales State Government.
"To be able to create technology that can be useful for humanity, to be able to create technology that can solve diseases, optimise weather patterns -- have all the implications to make the world a better place and understand the world -- is what drives me," said Simmons, who is also Director of the Australian Research Council Centre of Excellence for Quantum Computation & Communication Technology (CQC2T).
In a statement released by UNSW in March, Simmons, said her team's work is inspired by the late American physicist Richard Feynman, whose birth centenary is on Friday.
Feynman is known for his path-breaking contribution to quantum theory -- especially its electrodynamics, which won him the Nobel Prize.
"Feynman said: 'What I cannot create, I do not understand'. We are enacting that strategy systematically, from the ground up, atom by atom," Simmons said.
"In placing our phosphorus atoms in the silicon to make a qubit, we have demonstrated that we can use a scanning probe to directly measure the atom's wave function, which tells us its exact physical location in the chip. We are the only group in the world who can actually see where our qubits are.
"Our competitive advantage is that we can put our high-quality qubit where we want it in the chip, see what we've made, and then measure how it behaves. We can add another qubit nearby and see how the two wave functions interact. And then we can start to generate replicas of the devices we have created," she said.
The team's latest advance - the first observation of controllable interactions between two qubits - was published in the journal Nature Communications.

Allahabad HC orders probe into 'reinstatement' of teacher in UP's Barabanki
Lucknow (PTI): The Lucknow Bench of the Allahabad High Court on Friday ordered a probe by the special task force (STF) into alleged irregularities in the rejoining of a teacher at City Intermediate College in Barabanki, observing that the reinstatement appeared to be prima facie illegal.
The court also directed the recovery of the salary paid to the teacher during the disputed period.
A bench of Justice Rajeev Singh passed the order on a petition filed by the college management committee. The court expressed doubts over the roles of the District Inspector of Schools (DIOS), Barabanki, the college principal and the teacher concerned and hence, directed a detailed inquiry into the matter.
Taking note of alleged manipulation of records and misleading submissions, the court ordered the immediate transfer of the Barabanki DIOS to ensure a fair probe. It also directed the initiation of disciplinary proceedings against the then joint director of education of the Ayodhya division.
In its order, the court found that the teacher, Abhay Kumar, was initially appointed as an assistant teacher in 2018 but joined an Eklavya Model Residential School in Chhattisgarh as a lecturer in June 2024 without obtaining permission from the management. His subsequent request to retain the lien was rejected.
Despite this, he was allowed to rejoin the Barabanki College in September 2025 on the directions of the joint director of education and the DIOS, and was even paid the salary for October 2025. The court termed the rejoining "wholly illegal" and lacking any legal basis.
The bench also expressed concern over lapses in communication within the education department and directed the Uttar Pradesh chief secretary to ensure that official orders are communicated through email and WhatsApp as well, to prevent disputes.
The matter is next listed for hearing on May 28 when a compliance report is sought.
