Xanadu reports Aurora, a networked photonic quantum computer built from 35 chips

What was demonstrated
Xanadu announced Aurora, a modular photonic quantum computer built from 35 photonic chips, with 12 qubits and about 13 km of fibre optics in total, described as operating at room temperature. The company says the results were published in Nature and quantified optical loss tolerances, but its announcement gives no numerical loss figure.
Why it matters
Xanadu presents Aurora as evidence that photonic systems can be scaled and networked in modular racks. The result is a company-reported system demonstration, and it may help show that photonic hardware can be built beyond single-chip experiments.
Caveats
- The company announcement is the main source for the figures here. The full text of the Nature paper could not be read, so its numbers are not confirmed independently.
- The system is not fault tolerant. Xanadu's announcement names optical loss as the next major obstacle to fault tolerance.
- The announcement gives no optical loss figure, so the loss tolerances reported in the paper cannot be assessed from this record.
