Temasek-backed Psiquantum to build first commercial quantum computer
PSIQUANTUM has announced plans to build the world’s first commercial quantum computer in Brisbane, Australia.
The Temasek-backed quantum computing startup said on Tuesday (Apr 30) that it has secured US$620 million worth of funding from the Australian and Queensland governments, with a target to build a commercial quantum computer by 2027.
Psiquantum will build a utilityscale quantum computer, which is capable of error correction, allowing it to complete billions of computational steps.
Without error correction, quantum computers cannot perform more than a dozen or so computational steps without errors introduced by quantum noise.
“A utility-scale quantum computer represents an opportunity to construct a new, practical foundation of computational infrastructure, and in so doing ignite the next industrial revolution,” said Professor Jeremy O’brien, Psiquantum’s chief executive officer.
Building the first commercially available quantum computer will involve building increasingly larger and more sophisticated systems ahead of the 2027 target launch.
O’brien likened the task to constructing a small data centre or high-performance computer, with racks of equipment being connected together.
Like data centres, quantum computers need cooling on an industrial level.
“Each of these cabinets contains hundreds of silicon chips – half of them are photonic, half of them electronic. They’re all wired up electrically together, interconnected optically using conventional telecommunication fibres,” said O’brien.
Psiquantum chose Brisbane as the project site due to its connection with the locale – its photonics approach was conceived in its laboratory there, as well as in Los Alamos, New Mexico in the US.
O’brien also cited the location’s highly educated and skilled workforce, adding that Australia is “blessed with natural resources of sun, wind and space”. This is relevant to one of quantum computing’s “hugely significant” application domains, which is climate change.
Temasek’s investment in Psiquantum represents its interest in emerging technologies that could play a role in enabling innovation and creating economic value. Quantum computing could also bring about the unattainable category of computer-generated data to train artificial intelligence models, noted Russell Tham, head of emerging technologies at Temasek.
“This form of computing at utility-scale – that can operate without errors – will unleash a new wave of innovation in material science, drug discovery, logistics and many other fields,” he said.
