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.

Not having memorial for Manmohan Singh deliberate insult to India's 1st Sikh PM: Jairam Ramesh
New Delhi, Dec 27: The Congress on Friday said that not finding a location for the cremation and memorial for Manmohan Singh is a deliberate insult to the country's first Sikh prime minister.
The Congress raked up the issue after the Union home ministry said in a statement that Singh's last rites will be held at New Delhi's Nigambodh Ghat at 11:45 AM on Saturday with full state honours.
Congress general secretary Jairam Ramesh said party president Mallikarjun Kharge wrote to Prime Minister Narendra Modi, urging him to conduct Singh's last rites at a location where a memorial could be built to honour his legacy.
"The people of our country are simply unable to understand why the Government of India could not find a location for his cremation and memorial that is befitting of his global stature, record of outstanding achievements, and exemplary service to the nation for decades," Ramesh said in a post on X.
"This is nothing but a deliberate insult to the first Sikh Prime Minister of India, Dr. Manmohan Singh," the Congress leader said.
Kharge wrote the letter after speaking to Modi about setting up a memorial for Singh, who was a two-term prime minister revered by the people of the country.
"Apropos our telephonic conversation today morning, wherein I made a request to hold Dr Manmohan Singh's last rites, which will take place tomorrow i.e. 28th December 2024, at his final resting place that would be a sacrosanct venue for memorial of the great son of India.
"This is in keeping with such tradition of having memorials of statesmen and former Prime Ministers at the very place of their funerals," Kharge said in his two-page letter.
The Congress chief said Dr Manmohan Singh holds a highly revered place in the psyche of the country and the people of this nation, and his contributions and achievements were phenomenal.
He also said that Dr Singh's erudition on economic and fiscal matters came from his vast experience as the governor of the Reserve Bank of India, chief economic advisor to the government of India and in various other capacities in several organisations, and the respect and regard that world leaders had for him bears testimony to this fact.
Kharge said Singh's wise counsel, leadership and contribution in mitigating the global economic financial crisis is well-acknowledged. He also recalled President Obama's words when as the US president, he mentioned that "whenever the Indian prime minister speaks, the whole world listens to him".
He also said that when the nation was in the throes of a grave economic crisis, it was Dr Manmohan Singh, along with former prime minister P V Narasimha Rao, who took India out of the crisis and also led the country towards economic prosperity and stability.
The nation today reaps the benefits of the robust economic foundations built by them, Kharge noted.
"Coming from a humble background and having experienced the pains and sufferings of the Partition, it is through his sheer grit and determination that he rose to become one of the leading statesmen of the world. I hope and trust that befitting stature of Dr Manmohan Singh, request to have the funeral of Dr Singh at a place where his memorial can be built, will be acceded," Kharge said in the letter.
Congress Legislature Party leader in Punjab assembly Pratap Singh Bajwa also separately urged Prime Minister Modi to have Manmohan Singh's funeral at a place where a memorial could be built later in his honour.
"I urge Prime Minister @narendramodi to honour Dr Manmohan Singh, one of the most towering Sikhs of modern times, with a memorial befitting his immense contributions to our nation. Rising from humble beginnings in a historic state, representing a community that has always stood steadfast for India's unity and progress, Dr Singh's life is a testament to intellect, integrity, and selfless service," he posted on X.
Bajwa said Punjabis across faiths and political lines unite in their heartfelt plea to recognise this son of Punjab, who played an instrumental role in shaping India's destiny, with the respect he deserves.
Shiromani Akali Dal leader Sukhbir Singh Badal claimed the Centre has "declined" the request of Manmohan Singh's family for performing the funeral and last rites at a place where an appropriate memorial may be built.
There is no official word from the government on Kharge's request.
However, Badal took to X to post, "Shocking and unbelievable! It is condemnable in the extreme that Union Govt has declined the request of Dr Manmohan Singh Ji's family for performing the funeral and last rites of the highly distinguished leader at a place where an appropriate and historic memorial may be built to commemorate his unparalleled services to the nation."
He further said this place should be Raj Ghat.
"This will be in keeping with the settled practice and tradition followed in the past," Badal said.
He said it is "inexplicable" why the government is "showing such disrespect to the great leader who was the only member of the Sikh community to rise to become the Prime Minister".
"As of now, the cremation is slated to be performed at the common cremation ground at Nigambodh ghat. I am unable to believe that the BJP govt's bias would go to such extremes in utter disregard of the towering global stature which Dr Manmohan Singh ji enjoyed and will always enjoy," Badal further said in his post.
He said Singh took the country to great international heights.
"Our political differences with the Congress apart, we have always held Dr Manmohan Singh in the highest esteem as he transcends politics and political affiliations. He belongs to the entire nation.
"Dr Sahib showed great sensitivity and compassion in his dealings with Shiromani Akali Dal over Sikh and Punjab issues," said Badal urging Modi to "intervene personally to change this deplorable decision of the government".
Singh passed away on Thursday night at Delhi's All India Institute of Medical Sciences (AIIMS) at the age of 92.
आज सुबह कांग्रेस अध्यक्ष ने प्रधानमंत्री को पत्र लिखकर प्रस्ताव दिया था कि पूर्व प्रधानमंत्री डॉ. मनमोहन सिंह का अंतिम संस्कार ऐसे स्थान पर किया जाए जहां उनकी विरासत का सम्मान करने के लिए एक स्मारक बनाया जा सके।
