📚 New Publication!

We are excited to share that Jiaying (Claire) Yang from 202Q-lab has just published a new paper: Deterministic Generation of Frequency-Bin-Encoded Microwave Photons, in collaboration with researchers from Chalmers and Ericsson.

📄 Read the paper: Phys. Rev. Lett. 134, 240803 (2025)

In this work, the team tackles a key challenge in building scalable quantum networks: reliably transferring quantum information between distant quantum processors. Using superconducting circuits, they developed a method to encode quantum information into two distinct frequency bins of a microwave photon — a bit like sending the same message over two radio stations at once. This clever trick allows the receiver to detect if something went wrong during transmission, thanks to built-in error detection.

✨ The result? A high-fidelity quantum state transfer protocol with 94.9% process fidelity, offering a practical step toward robust and scalable quantum communication.

🎬 We also had the chance to sit down with Jiaying (Claire), who explains the research and its potential impact. Watch the video here: https://youtu.be/0BaJSnfBYTY
