AKKA Technologies : Quantum Control Electronics

QUANTUM CONTROL ELECTRONICS

Operating quantum processors requires high-performance, classical control electronics. Within the IQuAn project, AKKA & Modis develop robust, scalable, real-time electronics based on industry standards to control quantum computations with trapped ions. Key electronic components are analog signal and radio frequency arbitrary waveform generators to drive versatile pulse shapes of high dynamic range, purity and sampling. These signals either directly control the ions or modulate laser-generated, optical control signals. The electronics are designed for reliable, automated operation and high scalability to operate quantum processors of 100 ions and more, which will enable novel computations within a hybrid quantum processor- high performance computing (HPC) setup.

DC-AWGs: For IQuAn, we have developed a 2nd generation analog signal generator card which combines an embedded control and processing unit with 16 parallel, highly flexible arbitrary waveform generators, low-noise DACs and amplifiers.

High agility: 20 ns sampling, rise & fall in 200 ns to 1 µs, jitter < 1 µsHigh parallelization: 16 separate output channels per cardRF-AWGs: For IQuAn, we are developing a 1st generation radio frequency generator card which combines an embedded control and processing unit with two parallel, high frequency, tunable arbitrary waveform generators, high-speed DACs and amplifiers.

The high-performance control electronics of AKKA & Modis comprise precision, flexibility, agility, robustness, and scalability to control and drive a wide range of precision experiments such as quantum computation but they are also suitable for precision test stands. The system-on-a-chip architecture makes each card fully independent, enables embedded, real-time processing capabilities, and full connectivity to other electronics and control units.
