A low-noise, flexible and scalable control paradigm for quantum computing in the NISQ era

In the race towards quantum computers with real-life applications, major challenges have to be overcome: improving the quality of qubits and operations, scaling up the number of qubits, and harnessing algorithms with error mitigation and correction strategies. Crucial to this end is the control stack that orchestrates experiment execution, generates analog control pulses and interprets algorithm outcomes. We battle these challenges by providing hardware stacks that combine low noise and drift, a novel distributed instruction set architecture (ISA) and a scalable infrastructure for low-latency feedback. By enriching our distributed ISA with low-level access to pulse amplitudes, offsets and modulation phases, it allows users to bypass slow communication via external digital interfaces. This creates a system with wide applications in quantum computing and opens up new avenues in quantum error correction and efficient execution of calibration routines and variational quantum algorithms (VQA).
