Quantum Computing

Real-time Control Electronics and Operating System

Electronics for the future

Quantum computing is the only technology known today to have the potential to outperform classical computers. Problems that used to be unsolvable in the past may now find their solutions. This will lead to quantum leaps in all technological fields, heralding a new quantum era.

Building a quantum computer poses numerous engineering challenges as individual quantum bits, for example trapped ions, have to be isolated, manipulated, entangled, and measured in a fully controlled way. Special importance is attached to the classical control electronics that drive the interactions with the qubits. These have to combine precision, flexibility, speed, and scalability in order to unleash the quantum advantage.

Our core competences

— Design

We coalesce state-of-the-art quantum processor chips from our academic research partners with high-precision, classical control electronics based on industry standards. We have designed a quantum computing infrastructure that focuses on robustness, scalability, and real-time capabilities. This enables continuous and automated operation, optimal operation and dynamic decision making, and scalability to also master tomorrow’s systems.

— Construction

We develop high-precision control electronics including low-noise, high-speed direct current (DC) and radio frequency (RF) generators, main-controller boards, and backplane connectors. These electronics are built around system-on-a-chip making them fully scalable, drive massively parallel control sequences, and offer integrated real-time processing capabilities for dynamic sequencing. Individual components can work solitary, master entire systems, or be externally controlled.

— Consulting

We build on more than five years of research and development experience of quantum control hardware and software for academic deployment. We offer a broad and detailed portfolio to consult future users on how to design a quantum control electronics infrastructure, deploy quantum technologies, and leverage the quantum potential to solve unsolved problems.
