No IPO announced
Quantum Brilliance shares are not available on public exchanges. See below for listed alternatives with similar technology.
Quantum Brilliance is an Australian-German company building quantum accelerators from nitrogen-vacancy (NV) centers in synthetic diamond — qubits that operate at room temperature without cryogenics or vacuum systems. Its vision is miniaturized "quantum accelerator cards" that slot into ordinary servers, vehicles and edge devices rather than data-center-sized machines.
The company raised an $18M Series A in 2023 (Main Sequence, Breakthrough Victoria) with subsequent government-backed extensions, and has deployed room-temperature quantum systems at the Pawsey Supercomputing Centre in Australia and with German research institutions.
| Round | Amount | Date | Key Investors | Valuation |
|---|---|---|---|---|
| Series A + extensions | ~$50M total | 2023–2025 | Main Sequence, Breakthrough Victoria, InQTel, German + Australian government programs | — |
No listed pure-play uses diamond NV qubits. Sector exposure is available through the tracked pure-plays or the QTUM ETF.

Can you buy Quantum Brilliance stock?
No. Quantum Brilliance is private with no announced IPO plans.
What are diamond NV qubits?
Qubits made from nitrogen-vacancy defects in synthetic diamond. They hold quantum states at room temperature — no dilution refrigerator, no vacuum chamber — enabling small form-factor quantum devices, at the cost of slower scaling to high qubit counts.
Where are its systems deployed?
The Pawsey Supercomputing Centre in Perth runs its room-temperature system alongside classical HPC, with additional deployments through German research partnerships.
