There are a lot of buzzword sounding bits in this article, but this is still a cool (incremental) step from what I understand. This seems to be the key bit:
Similar quantum teleportation was achieved by researchers at Northwestern University in 2024, when they found a way to guide particles of light through 30 kilometres of fibre optic cable. However, Photonic says it has taken this a step further by successfully transferring information to a “remote processing node.”
Think of sending a letter by mail. Previous demonstrations of quantum teleportation were like successfully delivering a letter written in disappearing ink: if delivery was successful, its content couldn’t be used, a Photonic spokesperson explained. Photonic’s transmission would be the equivalent of successfully sending a letter written in permanent ink, so the information is permanently available on the other end.

One of Canada’s top quantum companies is claiming a breakthrough in transmitting information over a fibre optic network, in a step towards using quantum tech in everyday communications.
Vancouver-based Photonic announced today that it had successfully transmitted quantum information—encoded as qubits, which can exist in two states at once—across 30 kilometres of telecom giant Telus’s commercial fibre network. The company is levelling up its partnership with Telus, who is also an investor, to pursue quantum-safe networking projects together.
“This is just the beginning of real-world impacts we will jointly deliver,” Photonic CEO Paul Terry said in a statement.
Founded in 2016, Photonic has now raised $375 million CAD in its pursuit to develop a useful quantum computer and sell its services at scale. Terry previously told BetaKit that the company is “commercializing a new branch of physics,” by using a property of quantum physics called entanglement to network quantum computers together.
