(VentureBeat) PsiQuantum and Globalfoundries (GF) have teamed up to manufacture the chips that will become part of the Q1 quantum computer.
The system they’re working on now is the first milestone in PsiQuantum’s roadmap to deliver a commercially viable quantum computer with 1 million qubits (the basic unit of quantum information) and beyond. PsiQuantum believes silicon photonics, or combining optics with silicon chips, is the only way to scale beyond 1 million qubits and deliver an error-corrected, fault-tolerant, general-purpose quantum computer.
Globalfoundries’ silicon photonics manufacturing platform enables PsiQuantum to develop quantum chips that can be measured and tested for long-term performance reliability. This is critical to the ability to execute quantum algorithms, which require millions or billions of gate operations.
PsiQuantum and GF have now demonstrated a world-first ability to manufacture core quantum components, such as single-photon sources and single-photon detectors, with precision and in volume, using the standard manufacturing processes of GF’s world-leading semiconductor fab. The companies have also installed proprietary production and manufacturing equipment in two of Globalfoundries’ 300-millimeter factories to produce thousands of Q1 silicon photonic chips at its facility in upstate New York and state-of-the-art electronic control chips at its Fab 1 facility in Dresden, Germany.
