10 UK quantum computing startups riding Britain’s breakout funding year
Roundup of ten UK quantum startups, written in partnership with Parkwalk. ORCA's profile covers its room-temperature photonic PT Series, CUDA-Q integration, named customers and its staged funding approach, including the $15M Series A and the GXC photonics acquisition.
QUANTUM INSIDER: Quantum Companies Help Develop Hybrid AI for Immune Targeting Peptides
Researchers developed a hybrid quantum-classical AI system that designed immune-targeting peptides, with quantum-generated inputs improving peptide discovery for understudied HLA variants and producing laboratory-validated binders. The quantum-enhanced model generated more predicted strong-binding peptides than conventional approaches, with the largest improvements occurring for HLA variants that have limited training data.
WIRED: Using AI and Quantum Computing to Generate New Peptides
The Technical University of Denmark team ran their generative AI model for predicting proteins in conjunction with a quantum computer built by British startup ORCA Computing. The researchers used this hybrid technique to generate novel peptides—short chains of amino acids—capable of binding to specific proteins in the body. Making the peptides in the laboratory and testing whether these would bind to the particular proteins showed the model produced more successful peptides than its classical counterpart, with the strongest improvements where training data was rare.
TECH JOURNAL: ORCA aims to beat classical computers with PT-3 quantum system
Interview with Richard Murray from Commercialising Quantum Global 2026. He calls PT-3 a "quantum advantage machine" for optimisation and generative AI, due later in 2026. Also covers the Japan deployment, the Digital Realty lab deal and ORCA's capital efficient funding stance.

The trainability of photonic quantum circuits
Research from ORCA Computing, Imperial College London and the University of Oxford shows that photonic systems stay trainable as they scale, while maintaining a provable edge over classical methods. These are backed up by results from ORCA’s PT-2 photonic quantum accelerator.
Nonlinear photonic architecture for fault-tolerant quantum computing
ORCA's nonlinear photonic architecture lets photons interact directly, removing key failure points of linear-optics approaches. The result is lower resource overheads and far greater tolerance to optical loss (around 12%), a significant step towards scalable, fault-tolerant quantum computing.
Hybrid quantum-classical de novo design of MHC-binding peptides
Together with the Technical University of Denmark, ORCA has demonstrated the first end-to-end hybrid quantum-classical pipeline for designing functional peptides. Samples from an ORCA photonic quantum processor guided a generative AI model and increased the yield of strong binders, especially for understudied immune targets. Lab testing then confirmed that the designs worked, marking a concrete step towards quantum-accelerated vaccines and immunotherapies.
Quantum for Enterprise Data Centers: ORCA Computing’s Accelerator Approach to Current HPC infrastructure and Workloads
Hyperion Research's Chief Analyst for Quantum Computing, Bob Sorensen, discusses how ORCA’s photonic quantum systems bring scalable quantum acceleration directly into standard enterprise data centers to power AI, HPC, and optimisation workloads.
Photonic Quantum-Enhanced Knowledge Distillation
Developed with NVIDIA, Jij, Imperial College London and the University of Oxford, this framework uses a photonic quantum circuit to guide the training of a compact AI model as it learns from a larger one. The result is up to ~100× fewer parameters with competitive accuracy, and the finished model runs entirely on classical hardware.
Towards a Scalable Linear-Cavity Enhanced Warm-Vapour Photonic Quantum Memory
Many of ORCA's key technologies depend on strong interactions between light and rubidium atoms. This paper shows how a simple linear optical cavity can boost that interaction in a room-temperature quantum memory, cutting power requirements and device size by an order of magnitude. The compact design can be scaled into large arrays and points to a route towards single-photon optical nonlinearities.
