Xanadu Quantum Technologies Limited has successfully demonstrated an average 0.085 dB/facet edge-coupling loss, a critical metric for the feasibility and performance of photonic quantum computers. This achievement marks a significant milestone for the development of fault-tolerant systems and underscores the company's progress in delivering scalable quantum hardware. The result stems from the convergence of Xanadu's advancements in integrated photonic chip design, state-of-the-art fabrication techniques, and innovative packaging solutions.

The milestone was facilitated by the capabilities of Xanadu's internal advanced photonic chip packaging facility, which launched last year to accelerate the development of next-generation integrated photonic platforms. This facility plays a crucial role in the company's hardware development approach, spanning from chip design to final packaging.

"Minimizing loss is paramount to unlocking the full potential of photonic quantum computing," said Dr. Christian Weedbrook, Founder and Chief Executive Officer of Xanadu. "This loss achievement of 0.085 dB/facet is not just an incremental improvement; it represents a significant leap forward in our ability to deliver highly-efficient and scalable quantum hardware. It underscores the power of our hardware development approach, from chip design to final packaging."

Xanadu's success was enabled by continued collaboration with industry partners. Notably, a joint development agreement with Corning Inc focused on customized fibre and fibre-array solutions for low-loss networking of photonic quantum computing chips. Additionally, a strong collaboration with DISCO supported wafer singulation efforts.
