Xanadu's Q3 Net Loss Widens to $32.2 Million on R&D Push

Xanadu Quantum Technologies (NASDAQ:XNDU) posted third-quarter revenue of $1.3 million against a net loss of $32.2 million, as the photonic quantum computing company stepped up research spending to advance its hardware roadmap. The loss narrowed from $42.1 million in the second quarter but widened from $20.3 million a year earlier.

On the Nov. 11 earnings call, founder and CEO Christian Weedbrook said Xanadu remains focused on building a fault-tolerant quantum computer rather than chasing near-term revenue at the expense of that goal. Management targets a commercially viable system in 2029 or 2030, while cautioning that projections carry risks and uncertainties.

What did the hardware roadmap deliver?

Weedbrook reiterated targets of up to 200 logical qubits (error-corrected units of quantum information) in 2029, up to 500 in 2030, and at least 1,000 in 2031 and beyond. The company aims for error rates as low as 10-8 in 2029 and 10-16 the following year.

Reducing optical loss remains the most important engineering challenge, Weedbrook said. He clarified that the company's published loss roadmap marks the beginning of each year — meaning Xanadu expects to reach a loss level 10.2 times the fault-tolerance requirement by the beginning of 2027, not the end. The underlying plot and qubit targets have not changed. Xanadu will report the aggregate loss metric annually, Weedbrook said, because improvements do not necessarily arrive in a straight line or show measurable progress each quarter; an update is planned for the first quarter.

Component-level results included:

• An optical switch with loss of 7 millidecibels, down from roughly 20 millidecibels last year — which management believes is the lowest reported for an electro-optic switch of its class.
• A twofold reduction in loss for the on-chip homodyne detector over the past year.
• A more than threefold reduction for the fiber delay line since the start of 2026.

A multi-year partnership with GlobalFoundries aims to scale production of silicon nitride chips and single-photon detectors on a 300-millimeter line in Malta, New York. Collaborations with ASML and Bluefors will address waveguide loss and more compact detector cooling, respectively. The company expects to begin using its new 158,000-square-foot Inception research and manufacturing facility in Toronto early next year, which COO Rafal Janik said will increase packaging, testing and measurement capacity and support integrating different materials into single packages.

Where is revenue coming from?

Janik said Xanadu began generating revenue from commercial software during the quarter, with a small but growing enterprise base. RBC and Boez Allen are using its software for workforce training — RBC and Booz Allen, to be precise — while semiconductor materials company JSR signed a statement of work for a feasibility study involving simulation and resource estimation. Xanadu also launched Backline with AMD, an open platform connecting classical hardware with quantum systems for processing, decoding and control; Janik said the companies demonstrated end-to-end round trips of less than three microseconds on commercially available AMD hardware.

Revenue rose from $1 million a year earlier but fell from $1.5 million in the second quarter. CFO Michael Trzupek said revenue will fluctuate with the timing of contract work and partnership activity and is not expected to materially drive operations near term. Weedbrook said the company remains open to monetizing software or licensing hardware intellectual property, provided such opportunities do not distract from the main roadmap. Janik noted potential photonic-IP applications in data communications and telecommunications, without a market-size estimate for the optical switch.

What does the spending picture look like?

Research and development expense rose to approximately $25.6 million, up $5.9 million from the second quarter, driven by wafer spending, foundry-related process development, and higher compensation. General and administrative expense fell to roughly $9.2 million from $11.1 million. Adjusted EBITDA loss widened to $26.3 million from $21.3 million in the prior quarter and $15.4 million a year earlier.

Xanadu ended the quarter with $286.5 million in cash, down $26.3 million sequentially. It did not draw on its synthetic at-the-market facility (a share-issuance financing program); approximately $232.8 million remained available. Trzupek said the company evaluates market conditions and valuation when considering financing.

On the funding side, Xanadu signed an agreement for approximately CAD 140 million in Canadian federal support, released over time as qualifying research investments are made, and received provisional approval for up to $10 million in additional DARPA project funding. Trzupek said costs and capital expenditures are expected to rise in the fourth quarter, but declined to provide an operating-expense forecast.
