Harnessing Precision: SpinQ’s High-Performance Arbitrary Waveform Generator

2025.09.19 · Blog Harnessing Precision

In quantum control, waveform fidelity directly translates to gate fidelity. SpinQ’s QCM-AWG-2208A Arbitrary Waveform Generator delivers the ultra-precise, low-latency control pulses required to drive today’s leading quantum platforms—whether superconducting, trapped-ion, silicon spin, cold-atom, or NMR-based systems.

Key Features & Advantages

  • Eight DC-coupled, single-ended analog outputs
  • Up to 16-bit vertical resolution for sub-microvolt amplitude precision
  • 2 GSa/s real-time sampling rate on each channel
  • Inter-channel skew below 200 ps, guaranteeing synchronized multi-qubit operations
  • Expandable, modular design: scale control to hundreds of qubits with plug-and-play channels
  • FPGA-based hardware acceleration for custom waveform generation and low-latency updates

Optimized for Complex Quantum Control

The QCM-AWG-2208A’s wide bandwidth (DC–450 MHz) and deep on-board memory (512 MSamples/channel) enable the generation of:

  • Shaped pulses for error-mitigation via DRAG and optimal control theory
  • Dynamic decoupling sequences to prolong coherence
  • Multi-tone microwave pulses for frequency-multiplexed control
  • Real-time feedback loops in variational algorithms

Modular Scalability

SpinQ’s modular architecture lets you daisy-chain multiple AWG units, seamlessly expanding from a single 8-channel controller to a 100-channel control matrix. Each module fits a standard 19-inch rack and can be remote-upgraded via FPGA for future feature sets.

Beyond Quantum Computing

While purpose-built for cutting-edge quantum experiments, the QCM-AWG-2208A doubles as a general-purpose high-performance AWG for:

  • Radar signal generation
  • Electronic paramagnetic resonance spectroscopy
  • Ultrasonic testing and medical imaging research

Supporting the Quantum Ecosystem

Pair the AWG with SpinQ’s QCM Measurement & Control System, SpinQit programming framework, and QPU EDA tools to create a fully integrated, end-to-end quantum control solution. Together, they empower researchers and educators to design, implement, and iterate quantum experiments with laboratory-grade precision—all from a compact, turnkey system.

By combining superior waveform fidelity with unmatched synchronization and scalability, SpinQ’s QCM-AWG-2208A sets a new standard for quantum control electronics—unlocking more reliable gates, deeper circuit depths, and faster paths toward quantum advantage.
