Qblox offers fully integrated quantum control stacks designed for controlling and reading out semiconductor quantum dots-based spin qubits. Together with extensive scalability, Qblox’s comprehensive solutions aim to simplify complex measurements and significant acceleration of experiments by combining advanced sequence processors, AWGs, digitizers, and self-calibrated microwave capabilities in Cluster mainframe and hence, facilitating NISQ applications.

Users can configure a 19" mainframe with modules tailored to the frequency range and channel density required for their spin qubit devices. Qblox integrates its electronics seamlessly with the open-source software platform Quantify, resulting in a powerful toolset that reduces setup time and accelerates overall workflows. Parametrized operations provided by Q1 advanced sequence processors help avoid repetitive wave uploading, reducing overhead in software-controlled loops.

Qblox's Cluster modules offer adaptability to diverse spin qubit systems. Given the scalable and modular architecture of the Cluster mainframe, it is easily modified according to the channel type and/or density requirement of every type of spin qubit device. Cluster modules integrate FPGA technology with the analog front-end in a wide frequency range from DC to 18.5 GHz in both read-out and control parts of the experiments to meet all experimental requirements of spin-qubit-based applications.  While QCM and QCM-RF modules can be used to define quantum dots electrostatically and generate microwave control pulses, QRM and QRM-RF modules can read the quantum dots via charge sensing, lock-in type, or RF-reflectometry.

Qblox prioritizes high signal integrity, by ensuring the lowest noise and drift in its Cluster modules and SPI DC sources. This ensures keeping the quantum dots at desired conditions for a very long time to make complex spin-qubit experiments feasible. The proprietary backplane protocols SYNQ and LINQ enable synchronization and low-latency feedback. An accomplishment of Qblox’s architecture lies in the ability to control down to single charge level experiments based on electrostatically defined 1-D structures; quantum dots or shuttling channels. Coherently controlled multi gates and the energy levels facilitate single or multi-quantum dot operations by effectively modulating the potential landscape.
