Qblox Quantum Control Stack for Diamond Spins
Qblox offers a comprehensive quantum control stack designed for controlling and reading out spins in diamond. This integrated solution streamlines experiments and finds applications in quantum sensing, computing, and communication. The Qblox Cluster architecture includes advanced sequence processors, AWGs, local oscillators, analyzers, and digitizers, providing scalability and configurability.
Modular customization
Tailor an all-inclusive Qblox Cluster with modules that fit a diamond device's frequency and channel requirements.
Efficient and fast experiments
Efficient and fast experiments Q1 advanced sequence processors integrated into the Cluster enable agile sequencing, significantly speeding up experiments. Parametrized operations in the Q1 processors allow dynamic changes to amplitude, frequency, and phase, reducing repeated wave uploading and communication time overhead.
Low noise and interference
Qblox prioritizes analog performance, minimizing noise and interference. The QCM module demonstrates the lowest 1/f noise among comparable devices.

Qblox offers a comprehensive quantum control stack designed for controlling and reading out spins in diamonds. While the control modules can be used to drive optical modulators and for typical AWG operation with arbitrary long pulses, readout modules can count the triggers and from photon detectors. Ultrastable voltage sources can also be used to control the laser frequency and the energy levels of the defect center.
Flexible Module Configuration
Users can tailor an all-inclusive Qblox Cluster by choosing from different modules based on their diamond device's frequency and channel requirements. These modules include the Quantum Control Module (QCM), Quantum Readout Module (QRM), and Quantum Control Module RF (QCM-RF), each serving specific functions. These modules work cohesively through embedded protocols, SYNQ for synchronization, and LINQ for feedback.
Agile Sequencing and Parametrized Operations
Q1 advanced sequence processors within the Cluster enable agile sequencing, significantly speeding up experiments. Parametrized operations in the Q1 processors allow dynamic changes to amplitude, frequency, and phase, reducing the need for repeated wave uploading and communication time overhead. This approach enhances efficiency, especially in experiments like dark-ESR spectroscopy. Allowing arbitrary setting of modulation frequency and phase assures phase coherent or continuous operation. Frequency chirps are also possible by updating these parameters on the nanosecond scale.
High-Performance Analog Components
Qblox prioritizes analog performance, minimizing noise and interference. The QCM module demonstrates the lowest 1/f noise among comparable devices. Carefully chosen filtering reduces ringing effects, ensuring sharp step responses. SPI DC sources offer ultrastable DC voltage with galvanic isolation and gyrator-filtered power supplies to eliminate unwanted interference.
