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.

BJP worker’s 16-year-old son allegedly casts eight votes in Uttar Pradesh’s Farrukhabad; Video viral
Lucknow (Farrukhabad): A viral video has surfaced showing a 16-year-old son of a BJP worker allegedly casting eight votes to the saffron party during the ongoing general elections in Uttar Pradesh. The video has sparked controversy, and the opposition has urged for prompt action from the Election Commission of India, reports scroll.in.
The video shared by the Samajwadi Party President Akhilesh Yadav on micro-blogging site ‘X’, showed the youngster recording himself while casting multiple times in a series of instances. The incident reportedly took place in Khiri Pamaran village, which falls under the Aliganj Assembly constituency within the Farrukhabad parliamentary seat. Mukesh Rajput, the sitting MP, is the BJP candidate in this constituency. Polling in Farrukhabad occurred on May 13 during the fourth phase of the general election.
In the viral video, the youngster is seen casting eight votes in total, all for the BJP, one by one with different clippings.
The youngster in the video has been identified as Rajan Singh Thakur, confirmed his father, Anil Singh Thakur to the Scroll.in. Anil Singh Thakur is the gram pradhan (village head) of Khiri Pamaran and a member of the BJP.
Anil defending his son told the Scroll that the ‘Video misrepresented his son,’ and claimed that the voting was done when the machine was being tested in some instances and other clipping of him voting on behalf of mentally and physically disabled voters was merged and made into a video.
Despite the Anil's caims, the video has drawn significant criticism. Subhash Chandra Prajapati, the additional district magistrate of Farrukhabad, confirmed to the Scroll that the administration will file a case soon. He mentioned that the returning officer is investigating the matter following a directive from the chief electoral officer in Lucknow.
The opposition has been vocal in its criticism, with Akhilesh Yadav demanding action from the Election Commission. In his social media post, Yadav accused the BJP of undermining the electoral process and described the party's booth committee as a "loot committee." The Congress party also called on the Election Commission to take action, in a ‘X’ post the party wrote, “Dear Election Commission…are you watching..a boy is voting 8-8 times ... .at least wake up now.”
Congress leader Rahul Gandhi, took to ‘X’ to express, “Fearing and seeing their defeat, the BJP is attempting to undermine democracy by pressuring government machinery to deny the mandate. The Congress expects all officers performing election duties to remember their constitutional responsibilities despite any pressure from those in power. Otherwise, once the Indian National Developmental Inclusive Alliance (INDIA) bloc government is formed, actions will be taken to ensure that anyone will think ten times before violating their 'Oath to the Constitution'."
Following the video's circulation, Naval Kishor Shakya, the Samajwadi Party candidate in Farrukhabad, filed a complaint with the district election officer. Shakya's complaint alleges that Rajan Singh Thakur cast votes after snatching voter information slips from other voters and that he was assisted by Dinesh Thakur, the local police station's station house officer. Shakya has called for re-polling at the affected polling center.
In a related incident earlier in May, Gujarat Police arrested two BJP workers for allegedly casting bogus votes and live-streaming the act on social media in the Dahod constituency. The Election Commission conducted re-polling at the affected booth following the incident.
The opposition INDIA bloc, including the Congress and the Samajwadi Party, has repeatedly accused the Election Commission of failing to take prompt action against election model code of conduct violations.
अपनी हार सामने देख कर भाजपा जनादेश को झुठलाने के लिए सरकारी तंत्र पर दबाव बना कर लोकतंत्र को लूटना चाहती है।
— Rahul Gandhi (@RahulGandhi) May 19, 2024
कांग्रेस चुनावी ड्यूटी कर रहे सभी अधिकारियों से यह अपेक्षा करती है कि वो सत्ता के दबाव के सामने अपनी संवैधानिक ज़िम्मेदारी न भूलें।
वरना INDIA की सरकार बनते ही ऐसी… https://t.co/fk4wXL8QZy
