No IPO announced
Q.ANT shares are not available on public exchanges. See below for listed alternatives with similar technology.
Q.ANT is not a quantum computing company in the qubit sense — it builds analog photonic processors for AI and HPC workloads, and markets itself entirely around compute acceleration rather than quantum algorithms. Its "Native Processing Unit" runs computations as light rather than electricity, on a proprietary thin-film lithium-niobate-on-insulator chip platform that bonds lithium niobate to silicon wafers; the company says the approach can deliver roughly 30x the energy efficiency of CMOS silicon on certain AI/HPC workloads. It earns a place on this page because it spun out of industrial laser maker TRUMPF's photonics manufacturing arm — the same underlying optical technology base used by photonic quantum computing companies like Xanadu and Quandela — and is frequently covered alongside them in quantum-photonics industry reporting.
In July 2025, Q.ANT's Native Processing Server went live at Germany's Leibniz Supercomputing Centre (LRZ) — described as the first photonic AI processor deployed in an operational HPC environment. It closed a €62M (~$72M) Series A in July 2025, later extended to $80 million. Second-generation processors reached LRZ in March 2026, and IONOS signed as Q.ANT's first commercial Native Processing Server customer in May 2026.
| Round | Amount | Date | Key Investors | Valuation |
|---|---|---|---|---|
| Series A (2nd close) | $80M total | 2025 | Duquesne Family Office (added tranche) | — |
| Series A (1st close) | €62M (~$72M) | Jul 2025 | Cherry Ventures, UVC Partners, imec.xpand (co-leads), L-Bank, Verve Ventures, Grazia Equity, TRUMPF | — |
Q.ANT is photonic AI compute, not gate-model quantum computing — there is no direct listed comparable. Xanadu (XNDU) and Quantum Computing Inc (QUBT) are the closest public companies working with related photonic-chip technology.
Is Q.ANT a quantum computing company?
Not in the qubit sense. Q.ANT builds analog photonic processors that accelerate AI and HPC workloads using light instead of electricity. It shares underlying photonic-chip technology with photonic quantum computing firms but does not build or sell quantum computers.
Can you buy Q.ANT stock?
No. Q.ANT is private and has not announced an IPO.
How much has Q.ANT raised?
$80 million total, via a €62M Series A (July 2025) co-led by Cherry Ventures, UVC Partners and imec.xpand, extended with a further tranche from Duquesne Family Office.
