Nu Quantum
Develops the links needed for separate quantum processors to share entanglement and eventually work together. Its focus is connecting quantum computing nodes, rather than distributing encryption keys.

What it does. Where it fits.
Photonic interconnects: qubit-photon interfaces, a dynamic entangler and synchronized network control.
Who should look closer
Quantum hardware teams and researchers evaluating modular processor architectures and qubit-to-photon integration.
QubitWire’s editorial assessment of practical fit.Partner integration
A documented QNU product-prototype and trapped-ion networking testbed support technical discussions; the reviewed sources do not establish a public computing service.
Check the current access route ↗What has been demonstrated
Nu Quantum reports a rack-mounted networking prototype with 300 ns control latency. CERN independently confirms the White Rabbit timing collaboration and a prototype presentation. The February 2026 lab announcement describes trapped-ion interface testing as work ahead.
What remains unresolved
Controller specifications do not establish end-to-end remote-qubit fidelity or an operating distributed quantum computer. The quoted optical fidelity ceiling must not be treated as measured system fidelity.
The next question to watch
Can integrated remote-qubit experiments publish entanglement fidelity, sustained link rate and useful distributed operations together?
A research question, not a promised milestone.QubitWire coverage

- Nu Quantum launches Quantum Networking Unit ↗Organization-originated source · 12 Jun 2025
Company documents a rack-mounted QNU product-prototype, with 300 ns control latency and readiness for qubit integration; stated maximum fidelity is a hardware capability, not demonstrated end-to-end remote-qubit fidelity.
- Nu Quantum opens trapped-ion qubit networking laboratory ↗Organization-originated source · 10 Feb 2026
Laboratory opened for a multi-node networking testbed. Trapped-ion QPI proof and interconnection of commercial processors are described as forthcoming development work.
- Nu Quantum is the first industrial partner to use White Rabbit for quantum technology applications ↗External source (may be a collaborator) · Publication date not stated
CERN confirms the White Rabbit collaboration and Nu Quantum prototype presentation on 8 November 2024. No production deployment is established.
