Xanadu and GlobalFoundries Partner to Manufacture Photonic Quantum Computing Components: Aiming for a Move to a 300 mm Line

On October 6, Canadian photonic quantum computing company Xanadu
announced a strategic multi-year partnership
with semiconductor manufacturer GlobalFoundries (GF).
The companies aim to move key components for computing with light
to GF’s 300 mm production line in Malta, New York,
paving the way for large-scale manufacturing.

What Changes: From Lab Prototyping to Industrial Production

The partnership combines Xanadu’s expertise in photonic circuit design
and process development with GF’s semiconductor manufacturing capabilities.
The initial focus is on industrializing ultra-low-loss
silicon nitride (SiN) photonic circuits
and superconducting nanowire single-photon detectors (SNSPDs).

The companies plan to move these components
from lab-scale prototyping to production on GF’s 300 mm line.
The announcement concerns a partnership to advance that transition;
it does not announce the start of volume production
or the completion of a commercial quantum computer.

Circuits That Guide Light and Detectors That Read Results

According to the announcement, information in photonic quantum computing
is carried by photons.
Reading calculation outputs requires detectors
that can determine the number of photons in a single light pulse.
Xanadu has adopted SNSPDs for this purpose.

SiN photonic circuits, meanwhile, guide photons with minimal loss.
The company expects the adoption of SNSPDs
to dramatically increase computing speed
and reduce the number of chips the system requires.
It describes the combination of high-efficiency SNSPDs
and low-loss SiN photonics as the foundation
of its photonic quantum computing technology.
The announcement does not provide specific figures for these improvements.

LC Signal’s Perspective: A Manufacturing Foundation for the Next Demonstrators

The companies say the collaboration is expected to serve
as the manufacturing foundation for Xanadu’s upcoming
fault-tolerant demonstrators.
They are also exploring further collaboration
to develop high-performance quantum modules.

Including both the circuits that guide light
and the detectors that read results in the same manufacturing partnership
is a clear choice.
It can be seen as a move to prepare key components
for factory production as the company advances to its next demonstrators.
