Problem
Current quantum computing platforms rely on bulky cryogenic systems and high power consumption, limiting scalability and accessibility for many organizations. Existing qubit technologies also face challenges in integration, control complexity, and maintaining high gate fidelity at larger qubit counts.
Solution
Quantum Transistors delivers a single‑chip quantum processor that combines diamond‑based solid‑state color‑center qubits with silicon photonic interconnects, eliminating the need for extensive cooling infrastructure. Their proprietary diamond fabrication facility produces charge‑stable qubits that achieve 99.9988 % fidelity for two‑qubit gates. Photonic links routed through an on‑chip photonic integrated circuit enable low‑latency, interference‑free communication between qubits, while fiber ports allow the system to scale beyond a single die. The control plane is integrated directly on the chip using CMOS technology, reducing system complexity and power draw. This architecture provides a scalable, affordable quantum processing unit that can be deployed in data‑center or edge environments alongside classical CPUs and NPUs.
