Dell and NVIDIA achieve sub-4µs quantum control latency

Dell has announced validated sub-four-microsecond average latency between Dell PowerEdge servers and FPGAs using the NVIDIA NVQLink platform.

• Main announcement: Dell validated sub-four-microsecond average latency with the NVIDIA NVQLink platform using Dell PowerEdge servers (models: XE9680, XE7745, R7715, R770) as the real-time host (RTH), enabling real-time calibration, dynamic circuits, and quantum error correction. The validation included partner testing with Quantum Machines using an R7615 server connected to its OPX1000 PPU, demonstrating control across three QPUs and two architectures.
• Additional details & timeline: The deployment integrates with NVIDIA CUDA-Q and RoCE-based connectivity; Dell plans to validate NVQLink across additional Dell offerings and run tests in co-located deployments “over the coming months”, and its servers can also run quantum emulation and machine learning workloads alongside real-time quantum control.
