On November 5, 2025, Melbourne became home to a world-first: the Quantum Diamond Foundry, a commercial facility dedicated to producing quantum-grade synthetic diamonds at scale. Opened by Quantum Brilliance at their Notting Hill facility, this milestone reinforces Australia's position as a global leader in accessible quantum technologies—and validates the room-temperature approach that we at Quantonic believe will democratise quantum computing.

Note: Quantonic Legacy Innovations is not affiliated with Quantum Brilliance. We're covering this as a significant Australian quantum industry development that aligns with our shared vision of accessible, room-temperature quantum computing.

Why This Matters for Australian Quantum

The Quantum Diamond Foundry represents more than just a manufacturing facility—it's a statement about Australia's quantum future. With combined government investment of $31 million from the National Reconstruction Fund ($13 million) and Breakthrough Victoria ($18 million), this facility demonstrates national commitment to building sovereign quantum manufacturing capability.

$6B Projected Industry Value by 2045
19,400 Projected Australian Quantum Jobs
"By opening the world's first commercial Quantum Diamond Foundry, we are moving quantum out of the lab and into products that can be built, shipped, and used in everyday settings. This is about reliable devices at scale, created in Australia, serving customers worldwide." — Dr. Marcus Doherty, Co-Founder & CTO, Quantum Brilliance

Room-Temperature Quantum: Why It Matters

What makes Quantum Brilliance's approach particularly significant is their focus on room-temperature operation. Their diamond-based quantum technology uses nitrogen-vacancy (NV) centres in synthetic diamonds—stable qubits that operate without the cryogenic cooling required by superconducting systems.

💎 What Are Diamond Quantum Devices?

Diamond quantum devices use defects in synthetic diamond crystals (specifically nitrogen-vacancy centres) to create stable qubits. These defects have quantum properties that persist at room temperature, enabling compact quantum processors that don't require massive cooling infrastructure. Quantum Brilliance has already deployed room-temperature quantum accelerators to supercomputing facilities in Europe, the US, and Australia.

This approach mirrors our own philosophy at Quantonic with photonic quantum computing: making quantum accessible without the infrastructure barriers that have traditionally limited the technology to well-funded research labs.

Room-Temperature Quantum Approaches

Approach Operating Temp Key Advantage
Diamond (NV Centres) Room temperature Compact, ruggedised devices
Photonic Room temperature Inherent networking capability
Superconducting ~15 millikelvin Fast gate operations
Trapped Ion Room temp (vacuum) High gate fidelity

Implications for Education and Research

The foundry's establishment has direct implications for Australian universities and research institutions:

  • Local Supply Chain: Australian institutions can now access quantum-grade diamond components from a local supplier, reducing dependence on overseas manufacturing and simplifying procurement.
  • Workforce Development: The facility creates highly skilled jobs in quantum manufacturing and positions Victoria as a training ground for the quantum workforce Australia needs.
  • Research Collaboration: Quantum Brilliance's existing Research Hub for Diamond Quantum Materials with La Trobe University and RMIT University demonstrates the industry-academia partnerships that accelerate quantum education.
  • Accessible Hardware: Room-temperature devices lower the barrier to entry for institutions that can't support cryogenic infrastructure.

🇦🇺 Victoria's Growing Quantum Ecosystem

This foundry joins a growing Melbourne quantum ecosystem that includes university research groups, the IBM Quantum Hub at the University of Melbourne, and now Quantonic's own focus on photonic quantum platforms for education. Victoria is positioning itself as Australia's quantum heartland.

Applications Beyond Computing

While quantum computing captures headlines, Quantum Brilliance's diamond technology has broader applications that highlight the versatility of room-temperature quantum approaches:

  • GPS-Free Navigation: Quantum sensors for assured navigation without satellite dependence—critical for defence and remote operations.
  • Medical Diagnostics: Quantum sensing for accelerated neuromedicine development and advanced pathology.
  • Mineral Exploration: Enhanced sensing capabilities for Australia's resources sector.
  • Renewable Energy: Integration into renewable-energy infrastructure for improved efficiency.

These applications demonstrate why room-temperature quantum isn't just about convenience—it's about enabling deployment scenarios that cryogenic systems simply can't address.

What This Means for Quantonic's Mission

Quantum Brilliance's success validates a core thesis we share: that quantum computing's future isn't just about building bigger, colder machines. It's about making quantum accessible, deployable, and practical for everyday use.

While we focus on photonic approaches and they focus on diamond-based technology, we're working toward the same goal: bringing quantum computing out of elite facilities and into universities, research labs, and eventually classrooms. Their success strengthens the case for all room-temperature quantum technologies.

As Australia builds toward its National Quantum Strategy goals—$6 billion industry value and 19,400 jobs by 2045—facilities like the Quantum Diamond Foundry demonstrate that Australian innovation can compete on the world stage while prioritising accessibility and practicality.
