How to Scale a Quantum Computer: Part 1

SEEQC is built upon the fundamental premise that to deliver a commercially scalable and cost-effective quantum computing solution, classical readout, control, error correction, and data processing functions must be integrated within a quantum processor. Just as the greatest advances in modern classical computing occurred with digital chip-scale integration of key functions, leading to drastic reduction in system complexity, I/O count, and cost, the same will be required in quantum computing. We are developing a platform to deliver that integration.

In terms of scalability, the company is eliminating many of the challenges of building quantum computers with thousands or even millions of qubits. Other industry approaches to quantum computing involve unwieldy systems requiring numerous, costly coaxial cables and complex CMOS readout/control for each qubit. These systems can’t scale effectively to meet the needs of businesses.

SEEQC’s system design provides a significant reduction in noise and interference to maintain high fidelity quantum operations at scale. Because it combines cryogenically integrated quantum and classical processors, the full-stack system complexity, required input/output (I/O) count, and room-temperature equipment are dramatically reduced leading to a very cost-effective and scalable quantum computing system.

In addition to reducing system complexity, latency and cost, SEEQC’s unique expertise in SFQ for circuit design and manufacture enables the company to engineer systems that operate at about four orders of magnitude lower energy compared to equivalent CMOS-based systems. This is another critical element to building a scalable quantum-classical architecture.
