Qblox, a maker of scalable quantum control hardware, announced that its cluster now works with NVIDIA DGX Spark using the NVQLink interface. The integration achieves measured round‑trip latency below 4.0 µs on an RTX PRO 6000 Blackwell GPU and below 7.2 µs on the DGX Spark system. This lets a single desktop run quantum experiments together with AI and simulation code, and then move the same code to larger GPU‑based data‑center servers as the quantum system grows.

## The facts

- Latency < 4.0 µs on NVIDIA RTX PRO 6000 Blackwell
- Latency < 7.2 µs on NVIDIA DGX Spark

## Why it matters

Researchers can calibrate qubits and correct errors in real time on a desktop, speeding up development of larger quantum computers.
