Diraq Partners With Dell to Embed Silicon Quantum Processors in Enterprise Hardware

Diraq has formalised a partnership with Dell Technologies to integrate silicon-based quantum processing units directly into high-performance classical computing systems, according to Quantum Computing Report, one of at least four significant quantum industry deals announced on September 19, 2026 - a cluster of activity that underscores how aggressively the sector is pursuing commercial integration with established technology players.

What Happened

The Diraq-Dell agreement aims to couple Diraq's silicon spin qubit QPUs with Dell's enterprise-grade classical computing hardware. Silicon spin qubits are attractive for integration because they can, in principle, be manufactured using processes compatible with existing semiconductor fabrication - a potential advantage over superconducting or trapped-ion approaches that require more exotic environments. The company did not disclose financial terms of the partnership.

On the same day, Quantum Computing Report reported that Pasqal, the French neutral-atom quantum computing company, signed a three-year memorandum of understanding with LG CNS, the IT services arm of LG Group, to integrate Pasqal's neutral-atom QPUs into AI data center infrastructure. The three-year term gives the agreement more operational weight than a typical exploratory MoU, suggesting LG CNS is treating quantum hardware as a near-term data center planning consideration rather than a distant research project.

Meanwhile, Australian quantum startup OptQC disclosed that Mitsubishi Electric is expanding its strategic partnership with the company alongside a JPY 7 billion ($47 million USD) Series A2 funding round and plans for a new Tokyo research and development facility, Quantum Computing Report confirmed. The Tokyo expansion signals that OptQC is building operational depth in Japan, where Mitsubishi Electric represents a significant industrial customer base across energy, manufacturing, and defence-adjacent sectors.

In a separate development, Quantum Computing Report covered Quantum B securing a European patent for a Quantum Conference Key Agreement Protocol - a cryptographic method that extends quantum key distribution to multi-party conference settings rather than just point-to-point links. On the networking side, The Quantum Insider published an interview with Tom Darras, CEO of Welinq, who outlined the company's approach to scaling quantum computers by networking nodes through shared entanglement - a quantum interconnect strategy that could eventually allow modular QPU clusters to operate as a single logical machine.

Why It Matters

The pattern across all five stories is the same: quantum hardware companies are no longer pitching to research labs alone. They are closing deals with Dell, LG CNS, and Mitsubishi Electric - companies that run production enterprise infrastructure for Fortune 500 clients and major industrial conglomerates. That shift from laboratory partnerships to enterprise integrations represents a meaningful change in where quantum companies believe near-term revenue will come from.

For investors tracking the space, the $47 million OptQC round - backed by Mitsubishi Electric's expanded commitment - provides a concrete valuation signal in a funding environment where many deep-tech rounds have become more selective. The concentration of deals on a single date also suggests that major quantum conferences or coordinated industry announcements may be driving disclosure timing, worth monitoring for the next wave. Those evaluating the investment implications of quantum computing advances will note that the deals span four distinct hardware modalities: silicon spin (Diraq), neutral atom (Pasqal), photonic interconnect (Welinq), and quantum networking cryptography (Quantum B) - diversification that reflects genuine uncertainty about which physical substrate will dominate at scale.

Background

Quantum hardware today spans at least four major physical approaches, each with distinct engineering trade-offs. As the MachineHours encyclopedia entry on Quantum Hardware - Superconducting, Trapped Ion, Photonic and Topological Approaches Compared explains, no single platform has yet demonstrated a decisive advantage across all relevant metrics: qubit count, coherence time, gate fidelity, and manufacturability. Diraq's silicon spin approach targets the manufacturability axis, aiming to exploit semiconductor fabrication expertise. Pasqal's neutral-atom platform offers reconfigurable qubit arrays without fixed physical wiring, which suits certain optimisation problems common in AI workloads.

Welinq's entanglement-based networking approach addresses a structural ceiling that all single-node QPU architectures face: adding more qubits to one chip becomes physically harder beyond a certain scale, making modular networking an increasingly attractive path to larger logical qubit counts.

What to Watch

The three-year duration of the Pasqal-LG CNS MoU means concrete integration milestones should appear by late 2027 or 2028 - watch for announcements about specific data center deployments or benchmark results from that partnership. For OptQC, the Tokyo R&D facility will be a gauge of how quickly Mitsubishi Electric wants to move from strategic investment to applied engineering. On the cryptography side, Quantum B's European patent for its conference key agreement protocol positions the company for potential procurement conversations with EU institutions, particularly given ongoing European regulatory interest in post-quantum security standards. Welinq's entanglement networking thesis is longer-dated, but if modular quantum networking reaches even small-scale demonstrations in 2026 or 2027, it will reshape assumptions about how quantum compute capacity can be expanded without solving the monolithic chip scaling problem directly.
