Today's quantum computers are not yet powerful enough to deliver on this promise.
A key barrier is scalability. Scaling quantum systems remains one of the hardest engineering challenges.

The engineering challenge of scaling quantum
Scaling quantum computers from laboratory systems to large-scale machines remains one of the biggest challenges in the field, and a necessary step before quantum computing can deliver on its real-world promise. The electronics responsible for operating qubits typically sit outside the cryogenic environment where the processor must run.
Today's quantum computers require multiple control cables for every qubit. Scaling that architecture to thousands or millions of qubits quickly becomes impractical.
Wiring complexity
Thousands of cables connect room-temperature controllers to the quantum processor at the heart of the system, introducing bulk, cost, and signal noise that constrain scalability.
Thermal load
Control electronics dissipate heat, and even minimal thermal loads can disrupt qubit operations, placing a hard limit on the number of qubits that can be operated.
Cryogenic integration
Developing electronics that operate reliably within the cryogenic environment remains a significant challenge and an active focus of research and engineering across the field.
Addressing scalability with cryogenically optimized CMOS: control hardware engineered to run alongside the quantum processor inside the cryostat.

Cryo-optimized CMOS for scalable quantum systems
Cryo-optimized CMOS electronics are control electronics designed to operate in extremely low-temperature environments, the same cryogenic conditions in which quantum processors function.
The research behind cryo-CMOS technology
This technology builds on silicon MOSFETs, the core devices of modern CMOS, but specifically engineered using cryo-optimized FD-SOI technology to achieve ultra-low power and sharp switching at millikelvin temperatures.
