What DUALITY QUANTUM PHOTONICS LTD does

Duality Quantum Photonics Ltd is a Bristol, United Kingdom-based photonic hardware company that designs and manufactures thin film lithium niobate (TFLN) photonic chips and processors for high-speed signal processing and quantum computing applications. The company builds its chips on 200mm wafers using wafer-scale deep-UV lithography at sub-180nm resolution, with specialist features below 50nm via electron beam lithography, and fabricates the chips at a Southampton nanofabrication facility while running design operations from its Bristol headquarters. Its proprietary component portfolio includes ring resonators, vertically emitting grating couplers, electro-optic modulators, periodically poled lithium niobate waveguides, and multi-mode interferometers, assembled into processors that run critical algorithms in nanoseconds at orders-of-magnitude lower energy than electronic alternatives.

The company's revenue model is anchored on hardware sales of photonic processors and photonic chips, supplemented by photonic chip design, simulation, packaging, and engineering services, with a forward-looking extension into quantum computing systems through the Innovate UK-funded VELOX networked quantum computing testbed. Duality targets enterprise and government customers with mission-critical signal processing requirements, including fusion energy developers (UKAEA, Tokamak Energy) for real-time tokamak hotspot detection, telecommunications providers such as BT for quantum networking, defense and radar operators, healthcare monitoring applications, and research institutions pursuing fault-tolerant quantum computing. The go-to-market is direct enterprise field sales with no disclosed pricing, no consumer channels, and reliance on government grant funding (Innovate UK, National Quantum Computing Centre) alongside co-development partnerships with the University of Bristol, CSA Catapult, and Digital Catapult. The business is co-founded and operationally controlled by CEO Anthony Laing and CTO Alberto Politi, who bring 20 years of collaborative research from the University of Bristol's quantum photonics group.

Core offering

Duality designs and manufactures photonic processors and photonic chips built on thin film lithium niobate (TFLN) for nanosecond-scale high-speed data processing, signal processing, and fault-tolerant quantum computing applications. Processors are designed in Bristol and fabricated at a 200mm wafer deep-UV lithography facility in Southampton, and the company also operates the VELOX networked quantum computing testbed.

Product overview

Duality Quantum Photonics Ltd offers a portfolio of photonic computing products centered on low-power photonic processors built on thin film lithium niobate (TFLN). The core product line includes Photonic Chips (manufactured at the Southampton facility using 200mm wafer deep-UV lithography) and Photonic Processors that perform core computing kernels at nanosecond speeds. Quantum Computing represents the company's quantum processing unit offering, designed for fault-tolerant quantum computing with rapid error correction and modular networking. VELOX is a networked quantum computing testbed project funded by Innovate UK (£2.5m grant) that connects photonic processors into a modular quantum architecture. Hello Worlds - Fusion Diagnostics is a specific application of photonic processors for real-time tokamak fusion diagnostics, developed in collaboration with UKAEA and Tokamak Energy.
