Photon subtraction approach shows a novel method for producing quantum light
A sourced note from the 7 October 2026 morning scan. The figure of record is the original report, not this page.
Researchers at the University of Waterloo's Institute for Quantum Computing, including Michal Bajcsy, showed photon subtraction from light pulses using a solid-state quantum emitter coupled to a chiral optical waveguide, where a photon's spin sets its travel direction. The module needs only a single laser as input and could make non-classical light for communication and sensing more efficient. The paper is in npj Quantum Information; experimental proof-of-principle work is underway.
Why it matters
Canadian research result on integrated quantum photonics; good fit next to QuantumCore and the Xanadu manufacturing thread.
