An October 6 announcement describes a silicon-nitride cavity prototype fabricated by Honeywell Aerospace. The manufacturing route matters, but it is not yet a performance or production-yield benchmark.

A new preprint reports two tunable quantum-dot emitters, cryogenic routing and single-photon tests in one GaAs circuit. The integration matters more than the device count.

A distributed lattice-surgery design reaches a 50% interface-erasure threshold only when local noise is absent. At one error in a thousand, the advantage largely disappears.
