Xanadu Achieves 0.085 dB/Facet Edge-Coupling Loss Using In-House Packaging Facility
XNDU•Xanadu achieved an average 0.085 dB/facet edge-coupling loss in its latest photonic chips, setting a new industry benchmark for ultra-low loss performance. This milestone leveraged its in-house photonic packaging facility and collaborations with Corning Inc and DISCO for customized fibre-array solutions and wafer singulation.
1. Ultra-low Loss Milestone
Xanadu’s latest photonic chips demonstrated an average edge-coupling loss of just 0.085 dB/facet, marking the lowest loss metric reported for integrated photonic quantum hardware. This performance improvement is critical for enhancing photon transmission efficiency and reducing error rates in quantum computations.
2. In-House Packaging Facility
The achievement was enabled by Xanadu’s advanced photonic chip packaging facility launched last year, which integrates design, fabrication and packaging under one roof. This vertical integration accelerates development cycles and tightens quality control for next-generation photonic platforms.
3. Strategic Partnerships
Xanadu strengthened its results through a joint development agreement with Corning Inc to create customized fibre and fibre-array solutions, and collaborated with DISCO for precision wafer singulation. These partnerships optimize optical coupling and manufacturing throughput for scalable chip production.
4. Implications for Quantum Computing
By minimizing coupling losses, Xanadu advances the feasibility of fault-tolerant photonic quantum computers operating at room temperature. The milestone paves the way for more efficient quantum hardware that can be scaled for practical applications in computing and communications.
