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.
