The Qubit Timetag Module (QTM) adds digital signal generation and acquisition to the Cluster in a module optimized for optically addressable qubits.

The output facilitates fast and precisely timed TTL signals for direct laser control. While at the input, a configurable analog threshold and windowing with photon counting and timetag functionalities ensure fast and reliable optical readout.

The integration of signal generation and acquisition in a single control instrument ensures inherent synchronization, rendering triggers redundant.

The module houses eight independent pulse sequence cores, that each are routed to an input/output channel. The flexibility of real-time pulse sequencing allows for conditional feedback based on the measured photon count to coordinate the continuation of the control sequence.
