Xanadu的光子赌注：Aurora模块化量子计算机，首次光子学纳斯达克上市

做的是什么生意

Xanadu builds photonic quantum computers whose qubits are light; Aurora, its first modular machine, networks four room-temperature server racks - 35 chips, 12 qubits - over 13 km of fiber, with a roadmap to a networked million-qubit quantum data center by 2029.

启动资金：$275M PIPE at US$10 a share completed with the Crane Harbor SPAC merger, a deal announced in November 2025 at about a $3.6B valuation

起因

Xanadu was founded in Toronto in 2016 by Christian Weedbrook, a former University of Toronto postdoc, and got its start at the Creative Destruction Lab accelerator. Its founding bet was that photonic qubits - information encoded in light - could scale like data-center servers where chip-bound superconducting machines could not.

经过

In January 2025 Xanadu unveiled Aurora: four independent server racks, photonically networked, holding 35 photonic chips and 13 km of fiber, running 12 qubits at room temperature and automated for hours. It published the design in Nature the same month, and IEEE Spectrum and MIT Technology Review covered Aurora as the first modular quantum computer, while experts cautioned that high optical loss made it too error-prone for useful computation. Xanadu's answer was to keep cutting photon loss and to build a quantum data center in 2029. In November 2025 it agreed to merge with the Crane Harbor SPAC; the deal closed on March 26, 2026 with a $275M PIPE, and on March 27 Xanadu listed on Nasdaq and the TSX as XNDU - the first pure-play photonic quantum computing company to go public.

结果

Still running: Xanadu listed on Nasdaq and the TSX in March 2026 and is selling access to its machines, but Aurora remains a research-scale prototype - a first-of-kind milestone, not yet a computer that does useful work.
