PsiQuantum, the US startup with Australian cofounders, has raised a gobsmacking US$1 billion (A$1.5bn) in a spherical that’s greater than doubled its valuation in 4 years to US$7bn (A$10.5bn).
The California startup, based in Palo Alto in 2015 by expat Australian professors Jeremy O’Brien, Terry Rudolph, Mark Thompson and Dr Pete Shadbolt, hopes to construct the “world’s first useful quantum computer”. Its know-how makes use of photons as a illustration of qubits as an alternative of electrons.
PsiQuantum controversially landed $940 million (US$620m) in loans and fairness from the federal and Queensland governments in April 2024 to construct its first quantum pc in Brisbane, adjoining to the capital’s airport, by 2027.
A couple of months later it did an analogous deal in Chicago, scoring US$500m (A$760m) over 30 years, from varied native authorities to construct a quantum pc there by 2028.

Australian VC Blackbird, which first invested earlier than the inflow of presidency money throughout 2021’s US$450 million Collection D, which valued the enterprise at US$3.15bn (A$4.25 bn). Blackbird chipped into the Collection E, which was led by current backers BlackRock, Baillie Gifford and Singapore sovereign fund Temasek, supported by a number of new buyers together with Macquarie Capital, Nvidia’s NVentures, the Qatar Funding Authority (QIA) and Morgan Stanley’s Counterpoint World.
The elevate is $300 million greater than preliminary stories of the pc producer in search of $1.2 billion in March this 12 months.
PsiQuantum’s founding staff carried out the world’s first lab demonstration of a two-qubit logic gate utilizing single photons in Brisbane over 20 years in the past, invented built-in quantum photonics and ‘fusion-based’ quantum computing, and made a prototype quantum processor out there by way of the cloud in 2013.
The Collection E money goes in the direction of breaking floor on the quantum computing websites in Brisbane and Chicago, to deploy large-scale prototype techniques to validate techniques structure and integration, and bettering the efficiency of its quantum photonic chips and fault-tolerant structure.
PsiQuantum has built-in what it calls “the missing component for scaling optical quantum computing”, Barium Titanate (BTO), a high-performing electro-optic materials, into its manufacturing circulate for ultra-high-performance optical switches. The brand new funding will assist them scale up BTO manufacturing. A BTO-enabled optical change additionally has potential in next-generation AI supercomputers.
The corporate now has a worldwide staff of greater than 500 folks and lately started shifting its Bay Space groups into a brand new 12,000 square-metre Take a look at & Meeting facility in California. This facility offers the PsiQuantum staff the area, energy, and managed setting to allow mass manufacturing of sub-assemblies and uncooked supplies, together with 300mm BTO wafers. PsiQuantum will construct its largest intermediate check techniques at this new facility in California and on the firm’s future web site on the Illinois Quantum & Microelectronics Park (IQMP) in Chicago, the place the corporate will break floor later this 12 months.
‘The true factor’
PsiQuantum cofounder and CEO Jeremy O’Brien
Prof. Jeremy O’Brien, the CEO, stated that “only building the real thing—million-qubit-scale, fault-tolerant machines—will unlock the promise of quantum computing,” including that the mission is a grand engineering problem, not a science experiment.
“We tackled the hardest problems first—at the architectural and chip level—and are now mass-manufacturing best-in-class quantum photonic chips at a leading US semiconductor fab,” he stated.
“With this funding, we’re able to take the subsequent decisive steps to ship the complete potential of quantum computing.”
His cofounder and chief scientific officer, Dr Pete Shadbolt, stated they’d pushed the know-how to an unprecedented degree of maturity and efficiency during the last 9 years since they began.
“We now have the chips, we’ve got the switches, we’ve got a scalable cooling know-how, we will do networking, we’ve got discovered the websites, we’ve got the industrial motive and the federal government help – we’re able to get on and construct utility-scale techniques.”
In addition to the funding from NVIDIA, PsiQuantum can also be collaborating with the chip maker on a number of fronts together with quantum algorithms and software program, GPU-QPU integration and PsiQuantum’s silicon photonics platform.
Blackbird associate Michael Tolo stated the Collection E “cements” the corporate’s path to ship the world’s first helpful quantum pc.
For Australia, this milestone is recognition of the progress and consistency PsiQuantum has revamped the previous 18 months, and demonstrates Australia’s alternative to turn out to be a worldwide chief in quantum computing. We love the PsiQuantum staff’s braveness to take the trail much less travelled,” he stated.
