Our ARTIQ (Advanced Real-Time Infrastructure for Quantum physics) testbed lets users develop and validate experiment code before running it on similar systems with live optical and RF sources. ARTIQ is an open-source control system in which experiments are written in a high-level, Python-based language and compiled to run on FPGA hardware with nanosecond timing resolution and sub-microsecond latency.
The testbed is built on Sinara hardware:
Kasli-SoC controller: runs experiment kernels on a 1 GHz CPU with hardware floating point, so heavier computations can run on the core device with low latency.
8 TTL channels (SMA): each channel can be set as an input or output, with selectable 50 Ω termination.
4 DDS channels (Urukul AD9910): RF output from roughly 1 MHz to 500 MHz, with sub-Hz frequency resolution, controlled phase steps, and accurate amplitude control.
Phaser upconverter: two IQ channels at 1.25 GS/s, upconverted to 0.3–4.8 GHz, for multi-tone RF generation.
32 DAC channels (Zotino): 16-bit analog outputs with a 1 MS/s update rate shared across the channels.
8 ADC channels (Sampler): 16-bit analog inputs with programmable full-scale ranges from ±10 mV to ±10 V.
Camera input (Grabber): a Camera Link interface that processes configurable regions of interest in the FPGA.

Our QICK-DAWG testbed lets users develop and validate pulse sequences for nitrogen-vacancy centers and other quantum defects before running them on similar systems with live optical and RF sources. QICK-DAWG is an open-source software and firmware package that runs microwave pulses, laser gating, and readout from a single FPGA board through a Python interface. It includes ready-made sequences for ODMR, Rabi, Ramsey, Hahn echo, and T₁ measurements.
The testbed runs on a Real Digital RFSoC 4x2 board, with all signals on SMA connectors:
2 RF outputs: two RF DACs sampling at up to 9.85 GS/s, for directly synthesizing microwave control pulses.
4 RF inputs: four RF ADCs sampling at up to 5 GS/s, for readout.
External timing: clock, sync, and 1 PPS inputs for locking the board to an external reference or other instruments.

Our Neutral Atom Quantum Processor Testbed is focused on advancing optical technologies for scalable quantum computing. We develop and integrate new optical devices and control techniques to enable precise, large-scale manipulation of neutral atom arrays. The testbed fosters collaboration between atomic physicists and optical scientists, emphasizing the co-design of neutral atom architectures and integrated photonic systems. Using Rubidium-87 atoms, the system is designed with flexible optical access to enable rapid prototyping and testing of new optical control approaches. By innovating in optical modulation, device integration, and control strategies, we aim to build a foundation for Megaqubit-scale devices that can power utility-scale quantum applications.

This quantum control testbed centers on a single nitrogen-vacancy (NV) center in diamond and its surrounding nuclear spins in the carbon lattice. The system integrates an NV center with a solid immersion lens and an on-chip microwave antenna, coupled to a cryogenic confocal microscope and an open-source FPGA control system (ARTIQ). The combination of optical access and long spin coherence times in color center qubits offers a promising platform for scalable quantum networks. With this testbed, we plan to investigate problems in quantum noise spectroscopy, dynamical decoupling and control, open quantum systems, cluster state tomography and entanglement verification, and machine learning for quantum system characterization.
The project is supported by NSF award PHY-GRS-2233120 and NIST award 60NANB23D202.
