Xanadu Quantum Technologies and Thorlabs announced a partnership to co-develop customized optical fiber components aimed at scaling photonic quantum computing systems. The collaboration focuses on improving phase and polarization stability while reducing optical loss—two constraints that directly impact error rates and system scale in photonic quantum architectures.
The companies plan to translate novel component designs from laboratory proof-of-concept into high-volume manufacturing. By combining Xanadu’s photonic quantum hardware expertise with Thorlabs’ vertically integrated optics manufacturing, the effort targets manufacturable solutions that meet tight stability tolerances across fiber-linked subsystems without adding excess loss.
The work supports Xanadu’s roadmap toward utility-scale photonic quantum computers and aligns with its pending public listing through a business combination with Crane Harbor Acquisition Corp.. Access to industrial-scale photonics production aims to reduce physical qubit overhead and quantum error correction demands as systems grow.
- Partnership scope centers on customized fiber components for phase and polarization stability
- Objective includes lowering optical loss to reduce qubit overhead and error correction load
- Thorlabs provides precision manufacturing and volume scale for deployable components
- Effort supports Xanadu’s utility-scale photonic quantum computing roadmap
- Collaboration aligns with Xanadu’s planned public listing and capital raise
“We are pleased to work with Thorlabs on addressing this challenge,” said Christian Weedbrook, Chief Executive Officer and Founder of Xanadu. “Their deep expertise and ability to manufacture with high precision, at a high volume, and at a competitive cost makes them an invaluable partner.”
🌐 Analysis
Xanadu pursues a photonic quantum computing strategy based on continuous-variable photonics, integrated silicon photonics, and fiber-linked architectures rather than cryogenic superconducting qubits. Its approach relies on deterministic photon sources, interferometric stability, and tight control of phase and polarization across large optical networks—areas where component variability and drift directly translate into higher error rates and greater quantum error correction overhead. Xanadu also develops PennyLane, an open-source quantum software framework designed to bridge classical machine learning workflows with near-term and fault-tolerant quantum systems, positioning the company across both hardware and software layers.
In November 2025, Toronto-based Xanadu Quantum Technologies plans to go public through a merger with Crane Harbor Acquisition Corp., a SPAC listed on Nasdaq, valuing the combined company at approximately $3.6 billion. The deal, backed by $500 million in expected gross proceeds, includes a $275 million PIPE led by institutional investors such as AMD, BMO Global Asset Management, CIBC Asset Management, and OMERS Ventures. Upon completion, Xanadu will become the first and only publicly traded pure-play photonic quantum computing company, with shares listed on both Nasdaq and the Toronto Stock Exchange.
Founded in 2016, Xanadu has emerged as a global leader in photonic quantum computing, a modality that leverages photons instead of superconducting or trapped-ion systems. The company gained international recognition in 2022 after demonstrating quantum supremacy with its Borealis system, a 216-qubit photonic computer that solved a problem in two minutes that would have taken a classical supercomputer seven million years. In 2025, Xanadu introduced Aurora, the first networked, modular, and scalable quantum computer, and demonstrated real-time error correction decoding with photonic qubits. The company aims to achieve full fault tolerance by 2029, scaling to 100,000 physical qubits and 1,000 logical qubits—while computing at room temperature without cryogenics or laser cooling.
