The Qubit Readout and Control (QRC) module unlocks new possibilities in qubit readout and control for both research and high-performance computing applications. The QRC is a high channel density RF solution that offers excellent performance and adaptability to control a growing number of qubits with the highest fidelities inside the Qblox control stack.
Covering 100 MHz to 10 GHz, fully independent ports generate all the necessary signals for scalable control and readout for your qubits.
Unique DDS and single mixing combination ensure high SFDR, exceptional SNR, and full frequency range accuracy without recalibration.
Q1 real-time sequencer delivers fully deterministic, reliable performance for complex pulse sequences and measurement loops.
Channel-independent instantaneous bandwidth of >800 MHz, doubling to >1.6 GHz with channel-combining, or two arbitrary >800 MHz windows.
Avoid delays with gapless playback and create the fastest parameter update rate of 4 ns.
High-level open-source software Quantify streamlines easy scheduling, while the assembly layer can integrate with third-party tools like (e.g. Qiskit).
Combining the best of direct digital synthesis (DDS) and analog mixing technology, the Quantum Readout and Control (QRC) module represents a groundbreaking advancement in quantum control. By leveraging the high-frequency capabilities of DDS, the QRC eliminates the need for a second mixing stage as compared to the double super heterodyne technique (DSH), preserving the calibration-free advantage of DSH while reducing phase noise.
The QRC module ensures channel-independent frequency range coverage without gaps, providing maximum user flexibility. With its streamlined design, users can effortlessly select a primary operating frequency. The hardware will then automatically adjust the settings to provide the full bandwidth immediately available around the chosen center frequency. This seamless approach makes hardware limitations invisible to the user, enhancing usability and simplifying the operation process.
The Cluster mainframe can integrate up to 10 QRC modules, counting up to 80 microwave channels within a single 19” rack for seamless scalability. Designed for complete qubit readout and control, it synchronizes and links the QRC with the complete Qblox Cluster portfolio.
The Qblox Cluster uses unique, patented protocols to create scalable systems that function as a single unit:
SYNQ protocol guarantees < 1 ns synchronization of all channels, with ps level jitter and great phase coherence for precise qubit control and the highest fidelities.
LINQ protocol provides fast scalable feedback in < 400 ns, featuring all-to-all connectivity for conditional playback and conditional branching.
QRC is the high-channel density solution for superconducting systems toseamlessly scale up to 100s of qubits.
Provides all-in-one superconducting qubit control and readout, with each module supporting fully parallelized operations up to 5 qubits and a mainframe capacity of 50 qubits.
Compatible with a wide range of superconducting qubit types, including fluxoniums, transmons, and cat qubits.
Enables frequency-multiplexed readout up to 8 qubits on a single feedline in the bandwidth of > 800 MHz or >1.6 GHz in channel-combine mode.
QRC ensures precise signal processing to enable reliable and scalablespin-qubit systems.
Provides improved sensitivity at lower noise and high speed is provided by up to 8 multi-tone RF-reflectometry across a wide frequency range.
Enables high-fidelity operations with pulse resolution on a 1 ns time grid and a clean spectrum, limiting undesired excitations and error injection with high SFDR and SNR.
Facilitates running long quantum circuits with limited dephasing over time is facilitated by high output and phase stability.
QRC is the solution for high-quality multiplexed RF and MW control signals.
Enables driving multiple qubits via a single antenna is enabled by QRC’s ability to output 8 tones per output.
Provides full spin register control with automatic phase tracking, and optical transition readout by photon counting or time tagging for photon correlation experiments.
Enables EOM sweeps over a broad range is made ideal by multiplexing without reducing output power per tone, and the extended instantaneous bandwidth, thanks to the channel combine mode.
With 6 output and 2 input channels, the QRC interfaces with multiple qubits at once, supporting extensive signal requirements for superconducting, spin, and optically addressable qubits.
Engineered on the state-of-the-art RFSoC technology, QRC ensures precise control with high gate fidelities through an excellent signal-to-noise ratio and low phase noise.
Calibration-free operation and automatic signal path optimization enable rapid success. Seamless integration with the Qblox portfolio ensures synchronized ports and fast feedback across the entire stack.
"With our new Qubit Readout and Control module, customers can now increase both the number of qubits and the quality of the qubit itself. The increased number of microwave channels, which are fully independent, gives the user the scalability and flexibility to scale their quantum computing systems. With our one-of-a-kind signal generation strategy, we combine various techniques to deliver optimal analog performance over the full frequency range for the highest qubit fidelities."
