Qblox upgrades its DC solution with the new Quantum Source and Measurement (QSM) module and the DC Cluster. Along with its sourcing function, the measurement capability of the QSM makes it a unique instrument for transport experiments and qubit applications.

The DC Cluster mainframe supports up to 20 modules. Its modular design allows integration with Qblox’s QCM and QRM baseband modules within a single 19” DC Cluster mainframe. This makes the DC Cluster a fully integrated system that provides all essential functions for DC transport experiments in various device concepts.

The DC Cluster is fully compatible with both SYNQ and LINQ protocols, ensuring seamless integration with baseband, RF, and timetagging modules. To guarantee an interference-free connection between multiple Clusters, a SYNQ isolator is provided to further protect the DC Cluster’s ground-loop-free operation.

SYNQ protocol: Ensures fully deterministic timing of all outgoing signals by creating a synchronized start and establishes fixed timing relations between all the modules in the Cluster. SYNQ Isolator box is provided to establish SYNQ protocol between multiple Clusters to further protect ground-loop free operation.

LINQ protocol: Facilitates low-latency feedback with an arbitrary control flow by distributing the measurement outcomes to all modules.
