PsiQuantum and GF have demonstrated the ability to manufacture core quantum components, such as single-photon sources and single-photon detectors, with precision and in volume for the first time using standard CMOS manufacturing processes. The companies have also installed proprietary production and manufacturing equipment at GF’s 300mm Fab 1 facility in Dresden, Germany, for the control chips and at its 300mm fab in upstate New York to produce thousands of silicon photonic chips for the Q1 quantum computer.
The deal was announced in March: GF deal to help PsiQuantum get to 1M qubits . PsiQuantum’s Q1 system represents breakthroughs in silicon photonics, which the company believes is the only way to scale to 1 million-plus qubits and beyond and to deliver an error-corrected, fault-tolerant, general-purpose quantum computer. The founders include Jeremy O’Brien, a professor at Bristol University in the UK.
“In the past year, we have experienced a decade of technological change. Now, due to the digital transformation and the explosion of data we are faced with problems that require quantum computing to further accelerate the Renaissance of Compute,” said Amir Faintuch, senior vice president and general manager of Compute and Wired Infrastructure at GF. “PsiQuantum and GF’s partnership is a powerful combination of PsiQuantum’s photonic quantum computing expertise and GF’s silicon photonics manufacturing capability that will transform industries and technology applications across climate, energy, healthcare, materials science, and government.”
The GF process allows the quantum photonic chips to be characterised for long-term performance and reliability.
“This is a major achievement for both the quantum and semiconductor industries, demonstrating that it’s possible to build the critical components of a quantum computer on a silicon chip, using the standard manufacturing processes of a world-leading semiconductor fab,” said Pete Shadbolt, chief strategy officer and co-founder of PsiQuantum. “When we first envisioned PsiQuantum, we knew that scaling the system would be the existential question. Together with GlobalFoundries, we have validated the manufacturing path for silicon photonics
