Our proprietary architecture enables scaling to 10,000+ qubits , a 40-100× improvement over current systems.
Physivitis Ltd announces a fundamental breakthrough in quantum computing infrastructure: CMDM. This proprietary innovation directly addresses the most critical barrier to scaling quantum computers, the wiring bottleneck that has limited current systems to approximately 1,000-2,000 qubits.
Every major quantum computing company, from IBM to Google to emerging players across Europe and Asia, has publicly acknowledged that delivering control signals to large numbers of superconducting qubits is the primary obstacle to achieving their published roadmaps of 100,000 to 1,000,000 qubits. Until now, no comprehensive solution has been demonstrated.
The Problem We Solved
Superconducting qubits the leading platform for quantum computing must operate at temperatures near absolute zero, approximately 20 millikelvin. Each qubit requires microwave control signals delivered through coaxial cables from room-temperature electronics. This creates a fundamental thermal problem: each cable conducts heat into the cryogenic environment, and dilution refrigerators have extremely limited cooling capacity at their coldest stage.
Current architectures use a one-to-one wiring approach: one cable per qubit. With cooling capacity of only 10-20 microwatts at the mixing chamber stage, this approach hits a hard physical limit. The maths is unforgiving scaling to 10,000 qubits would require managing 20,000 to 30,000 cables, which is physically impossible within existing thermal constraints.
CMDM fundamentally changes how signals reach qubits. Rather than fighting the thermal budget, we’ve engineered a system that works within it whilst delivering unprecedented scaling capability. This is the enabling infrastructure the quantum industry has been waiting for. Rene C. Mugenzi, Physivitis Ltd
The CMDM Solution
CMDM introduces a revolutionary architecture that dramatically reduces the number of cables required from room temperature whilst enabling signal delivery to thousands of qubits simultaneously. Our proprietary technology operates at cryogenic temperatures with minimal thermal impact.
CMDM Key Capabilities
- 40-100× cable reduction: Supporting thousands of qubits with tens of cables instead of thousands.
- Sub-microwatt thermal dissipation: Operating well within dilution refrigerator thermal budgets.
- Modular, scalable architecture: Enabling incremental expansion without system redesign.
- Preserved quantum coherence: Signal routing that does not degrade qubit performance
- Compatible with existing infrastructure: Works with current dilution refrigerator technology.
The Future of Quantum Computing
CMDM enables a new generation of quantum computers that are more compact, more scalable, and more practical than anything possible with current technology. The transformation is dramatic:
Simulation Validation
CMDM has undergone rigorous simulation and theoretical validation across multiple domains:
Thermal Modelling
Complete heat flow analysis confirming operation within μW thermal budgets at 20 mK.
RF/Microwave Simulation
Channel isolation exceeding 40 dB with minimal insertion loss across operating band.
Quantum Backaction Analysis
Verified that signal routing preserves qubit coherence times.
Scalability Verification
Architecture validated for 10,000+ qubit configurations
The simulation results demonstrate that our unified design framework correctly predicts system behaviour across thermal, electromagnetic, and quantum mechanical domains simultaneously — a critical requirement for cryogenic quantum systems where these phenomena are deeply interconnected.
Industry Implications
CMDM represents enabling infrastructure for the entire quantum computing industry. Published roadmaps from IBM, Google, Intel, and others target qubit counts that are impossible to achieve with current wiring approaches. Our technology provides a pathway to realising these ambitions.
Target Applications
CMDM is designed for integration with superconducting qubit systems across multiple contexts: cloud quantum computing platforms, on-premise enterprise quantum systems, quantum research facilities, and hybrid quantum-classical computing centres. The modular nature of the architecture allows it to scale from hundreds to tens of thousands of qubits within a unified framework.
