Fully-integrated quantum control stacks from ultrastable DC to 18.5 GHz

The Cluster 19” mainframes integrate all the state-of-the-art electronics needed to control quantum computers. The dedicated hardware is tailored for the university research labs and industry R&D labs to reduce size, cost per qubit and maintenance costs. The Cluster Series is the ideal hardware for quantum setups scaling from a handful towards 100s of qubits. Control and readout tasks are assigned to different modules which operate at baseband (0 - 300 MHz) or in the microwave regime (2 - 18.5 GHz). The system provides control of single qubits, generation of pulses for two-qubit gates, supports multiplexed readout and operates with system-wide synchronization. The qubit control is managed by the QCM-RF module, which directly outputs RF signals in the range of 2-18.5 GHz. It integrates 6 AWG’s capable of generating complex baseband signals, two LO’s, and two IQ mixers. The module can self-calibrate its IQ mixer skewness, amplitude imbalance and LO leakage. Qubit readout is performed by the QRM-RF module which includes LO’s, mixers, 6 AWGs pulse generators and digitizers for multiplexed readout in the range of 2 - 18.5 GHz. The QRM has advanced binning and averaging capabilities and can store up to 131072 IQ measurement results in a single experimental run.
