Deltaflow.Control is a customisable software solution for generating high accuracy, high speed pulse sequences to control qubits using affordable off-the-shelf hardware.
Its decentralised architecture provides the scalability and performance required to enable practical quantum error correction.
Deltaflow.Control is currently available for trapped ion and cold atom qubits. Support for superconducting qubits is in development.
"Our experience with Deltaflow.Control and the Riverlane product team has been very positive. They’re always responsive and helpful, and are clearly focused on understanding and addressing the needs of researchers in the lab."
- Tracy Northup, Ingeborg Hochmair Professor of Experimental Physics, University of Innsbruck

Deltaflow.Control + Xilinx RFSoC
Deltaflow.Control integrates seamlessly with the Xilinx RFSoC ZCU111 Board to create a scalable high performance qubit control system providing:
- 8 RF outputs - frequency range 20-400 MHz / sampling rate up to 4Gsps / 14-bit amplitude resolution / 16-bit phase resolution / timing resolution up to 1ns
- 16 digital IOs - 4 inputs configurable as any combination of PMT inputs or external trigger inputs (on request) / 12 outputs
- External triggering to enable operation of Deltaflow.Control systems in satellite mode alongside 3rd party control systems

Hardware Kit for Xilinx RFSoC Boards
To fast track building a complete rack-mounted qubit control system based on Deltaflow.Control and the Xilinx RFSoC board, a kit of parts comprising casing, power supply, cabling and IO connectors is available from Riverlane on request.

Deltaflow.Control + Sinara
Deltaflow.Control brings scalability and a powerful and easy to use programming model to the Sinara open-source hardware ecosystem. Support is provided for setups comprising the Kasli controller, Urukul signal generation and TTL digital I/O modules.

The Journey To Scalable Qubit Control
To run the large scale error-corrected circuits that will be be needed to perform useful calculations, the next generation of qubit control systems must meet three key requirements.

How can physicists scale their Sinara qubit control systems at low risk?
Deltaflow.Control offers a hybrid solution that provides a stepping stone to scalability, so physicists can do more complex work without replacing their existing setup.

The hidden costs of homegrown qubit control systems
Quantum control engineer Mitch Peaks explains why physicists building qubits need a control system to progress their research.

Riverlane leads UK consortium to build auto-calibrated quantum control system ‘Deltaflow.Control’
Riverlane, which is building the operating system for error corrected quantum computers, is leading a UK-based consortium to build a system capable of controlling hundreds of qubits simultaneously across different types of quantum hardware.
