PRESS RELEASE — CDimension, an MIT spin-out building foundational computing hardware, announced it is delivering wafer-scale, high-quality 2D materials that directly address quantum computing’s biggest bottleneck: noise. Recently valued at $1 billion, the company’s single-crystalline 2D insulators provide the foundation for ultra-low noise qubits, extending coherence time and making practical error correction achievable. This paves the way for scalable quantum devices.
“Quantum computing is gaining momentum, but progress has been stalled by one critical bottleneck: noise. These random disturbances result in errors that prevent systems from scaling,” said Jiadi Zhu, CEO of CDimension. “Current approaches struggle to overcome this because they rely on imperfect materials that aren’t compatible with existing silicon infrastructure. Our wafer-scale, single-crystalline 2D insulators, however, reduce noise at the source. By addressing this challenge at the materials level, we are laying the groundwork for disruptive breakthroughs in quantum hardware.”
Investor Confidence and Long-Term Vision
CDimension is working with leading customers to accelerate the transition from fragile prototypes to manufacturable quantum systems. This momentum, alongside the company’s recent valuation, underscores investor confidence in its integration-ready approach and its broader vision to rebuild computing hardware from the materials level up.
CDimension’s long-term vision is to redefine the materials foundation of quantum computing. Rather than trying to scale quantum simply by adding more qubits, CDimension is focused on optimizing each qubit by reducing noise and extending coherence time. Once individual qubits are stable and reliable, more can be connected together, the essential step toward practical error correction and scalable systems.
Quantum’s Potential, and its Biggest Pain Point
Not long ago, the prevailing belief among industry leaders was that practical quantum computers were still decades away. But as companies such as NVIDIA revise their outlook, and major players like Google, Microsoft, and IBM follow suit, this timeline is increasingly being measured in years. Investors worldwide are now pouring billions into the sector, and even longtime skeptics acknowledge that quantum computing has the potential to revolutionize industries ranging from drug discovery and cryptography to finance, logistics, and beyond.
Yet progress has been slowed down by one central pain point: noise. Quantum devices are so fragile that the smallest physical defects or thermal disturbance can cause qubits to lose information, generating errors that halt computations. This vulnerability has kept most quantum systems confined to labs, far from commercial scale. Unless noise can be addressed, quantum computers will experience huge difficulties in surpassing classical machines in real-world tasks.
That’s the essence of CDimension’s bottom-up strategy: start with materials, then scale to integration and systems. In practice, this means CDimension’s wafer-scale 2D insulators are already enabling customers to work with quantum devices. And longer term, this approach cuts the roadmap to pure quantum devices in half, where scalable quantum hardware could be brought to market years sooner than previously expected.
CDimension’s Technology
The company’s proprietary technology mainly focuses on three aspects:
- Reducing Noise in Josephson Junctions- Replacing amorphous or polycrystalline oxides with single-crystalline, ultra-thin 2D insulators significantly increases coherence time and reduces two-level-system (TLS) noise. CDimension’s wafer-scale platform now enables these improvements to translate into scalable hardware.
- Monolithic Integration for Cryogenic Circuits- Incorporating monolithic 3D integrated circuits into cryogenic control systems decreases local heat generation near qubits, lowering thermal noise and enabling compact, energy-efficient designs.
- Scalable Quantum Chip Manufacturing- CDimension’s wafer-scale platform and standard production flows for 2D materials provide a manufacturable path for scaling quantum chips, greatly accelerating the development of practical quantum systems.
The Future of Computing
As silicon approaches its physical limits, CDimension’s 2D materials provide the new foundation for AI, robotics, and advanced computing. The near future will be hybrid, with semiconductors and quantum systems working side by side. In semiconductors, CDimension’s ultra-thin, low-leakage layers enable vertical stacking — delivering more compute in the same footprint with far lower power. In quantum, its single-crystalline 2D insulators cut noise and extend qubit coherence, unlocking error correction and scalability. By supporting both domains, CDimension’s platform bridges today’s computing needs and positions quantum as the future.
