Deltaflow.Control is a customisable 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.
Engineering Quantum Error Correction: The Deadtime Challenge
In this post, we’re examining deadtime and a new patent application from Riverlane that tackles this issue head on, helping to speed up your computations to the point where you won't even have time to put the kettle on (sorry).
Verification matters for the Quantum Error Correction Stack
Without design verification, we could not ensure that we’re controlling the qubits in the right way. It’s a necessary tool to ensure that we are building the right Quantum Error Correction Stack for our partner hardware companies.
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.
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.
