The Cluster is the world’s leading modular quantum control stack. The scalable and modular architecture ensures that the system is future-proof, and well-aligned with the development roadmaps of industrial labs and the growing demands of quantum experiments.
As a crucial element in a quantum computing setup, it enables scientists and engineers to do their experiments at the highest possible level today and allows them to scale up to the NISQ era with ease, no matter the qubit technology. 
The Qblox Cluster is a modular, scalable room temperature quantum control 19” rack system. The Cluster supports superconducting, spin, and NV center qubit technologies with all-to-all channel distribution, dedicated high- and low-level software, and inter-communicating modules to control and readout qubits over a wide frequency range (up to 18.5 GHz).
Qblox Cluster modules are fully integrated for all the functionalities required for qubit control and readout. Each module incorporates 6 cores of advanced sequence processors for real-time operations and state-of-the-art analog circuitry for excellent analog performance. Qblox’s proprietary SYNQ and LINQ protocols assure channel synchronicity below ns accuracy and establish a data distribution network for fast scalable feedback. The channels can input and output signals within a large frequency range from DC to 18.5 GHz.
Advanced sequence processing to overcome software bottlenecks
Q1 advanced sequence processors generate real-time parameterized pulses and allow on-board data processing. By eliminating software-controlled loops, experiments are sped up by orders of magnitude.
From today to NISQ applications
Cluster’s architecture enables researchers to seamlessly scale from a few qubits up to 100s of qubits, assuring the alignment with future roadmaps and the growing demands of quantum experiments. Hardware improvements allow a smooth transition from basic experiments to many-qubit quantum error correction algorithms.
All you need for various qubit platforms
Modularity assures various configurations to the requirements of various experimental settings. Single and 2-qubit gates, frequency multiplexing, various readouts, and spectroscopy measurements can be managed from the same system by configuring 4 modules.
About: Analog excellence for increased gate fidelity.
The Cluster modules are designed particularly for the generation of the best quality pulses for control of quantum systems. Record 1/f noise, 50 dBc SFDR over the full frequency range, and industry-standard phase noise to ensure the generating sequence of pulses with the highest precision. Low-temperature drift, ps jitter, and great relative phase relation between multiple channels establish a highly stable operation. Being equipped with Bessel-type filters reduces overshoot and ringing effects and offers the fastest rise times. Pre-distortion corrections are also implemented in the digital domain.
About: Fast Scalable Feedback with all-to-all connectivity.
Multiple cores of Q1 sequence processors result in distributed intelligence over the whole cluster mainframe, working seamlessly thanks to our proprietary SYNQ and LINQ protocols. Fast-scalable Feedback is built on top of these 120 processor cores in a single 19” rack with all-to-all connectivity. Up to 40 input channels can be linked to up to 80 output channels in the same time window of 364 ns for feedback operations, active reset, and quantum error correction algorithms.
About: High- and low-level software control.
Qblox provides a flexible high- and low-level software approach to control the Cluster modules.
The low-level language Q1ASM can be used to program complex pulse sequences by sending instructions directly to the Q1 sequence processor.
The high-level data acquisition framework allows programming quantum experiments in an intuitive way with pulse visualization tools and experiment libraries. Both software layers are Python-based and support QCoDeS drivers.
QCM:
The Qubit Control Module (QCM) is specifically engineered to be state-of-the-art in generating pulses in the baseband regime up to 400 MHz to replace conventional AWGs. The core of QCM’s technology lies in the Q1 advanced sequence processors and a high-end analog front-end to support quantum computing experiments. The highest channel density is assured with 4 analog outputs and 4 digital outputs per module, to form a massively scalable system by incorporating 80 AWG channels in a single 19” mainframe.
Pulses are generated in real-time by uploading waveforms in 16k wave memory and shaping the outputs by amplitude, offset, modulation frequency, and phase. Pulses can be defined in a 1 ns time grid, and the pulse parameters can be updated on the nanosecond scale. Orders of magnitude speedups are achieved by avoiding software-controlled loops and repeated wave uploading. The QCM module seamlessly unifies with other modules within the Cluster mainframe via our proprietary SYNQ and LINQ protocols. Synchronized start of all channels are guaranteed below 1 ns accuracy and the fast scalable feedback is achieved within ∼ 350 ns for active reset and error mitigation algorithms.
