Delta Gold Technologies Plc (USOTC:DGQTF) (AQSE:DGQ) has outlined new developments from its sponsored research partnerships with The Pennsylvania State University (Penn State) and the University of Toronto (U of T), highlighting advances that the company believes reinforce the commercial potential of its growing quantum technology intellectual property portfolio.
The update centres on research into gold-based quantum materials, with both university teams pursuing different approaches aimed at developing next-generation platforms for quantum computing, sensing and communications.
Penn State Identifies Gold Nanoclusters as a Distinct Quantum Platform
At Penn State, research led by Professor Ken Knapenberger has resulted in three patent applications that Delta expects to add to its intellectual property portfolio under the terms of its Sponsored Research Agreement.
According to the company, the work indicates that gold nanoclusters represent a new category of quantum material rather than an extension of existing technologies. The research examines how electron spin within the gold nanoclusters can be used to encode quantum information, with the particles acting as “super atoms.”
Delta said laboratory experiments funded through its research programme achieved approximately 40% spin-polarised photon emission. The research team believes this level of performance is unmatched among condensed-phase quantum material systems and compares favourably with current quantum technology platforms.
The company also noted that the nanoclusters demonstrated spin polarisation over timescales considered competitive with leading quantum technologies.
Other technical milestones highlighted by Delta include:
- Nanoclusters measuring roughly 9 angstroms in radius, offering a significantly smaller footprint than conventional microelectronics materials.
- Successful laboratory production at gram scale using straightforward synthesis methods, providing evidence of manufacturing scalability.
- Verification of a spin-photon interface across multiple frequencies, creating a potential foundation for future quantum communication networks.
Delta believes the existing patent applications represent the first stage of what could become a broader portfolio covering future discoveries and licensing opportunities.
Kenneth Knappenberger Jr., Department Head and Professor of Chemistry and Professor of Physics, at Penn State, commented: “What we have demonstrated with gold nanoclusters is, to my knowledge, a first in condensed-phase quantum materials: a spin-photon interface that is simultaneously long-lived, high-purity, and potentially chemically tunable across frequency windows. The approximately 40% spin-polarised emission we have recorded has not been achieved in any other material system I am aware of. That purity matters enormously — without spin alignment, entanglement and coherence operations either fail or require error-correction overhead that makes scalability impractical. I believe that our work with Delta gives the QIS community a platform that can be made-to-order for the application at hand, and that is a genuinely new capability for the field.”
R. Michael Jones, Chief Executive Officer of Delta Gold, commented: “The findings coming out of Penn State confirm what drew us to this research thesis in the first place: that gold, properly understood at the nanoscale and protected through robust IP, is a potential quantum platform with structural advantages. We look forward to the next steps as the research advances.”
University of Toronto Pursues Complementary Research Strategy
Delta also provided an update on its collaboration with the University of Toronto, where research is progressing under a separate sponsored agreement and follows the filing of a provisional patent application announced in May 2026.
The company confirmed it has funded a second year of research after encouraging initial findings, with the expectation that dedicated patent applications could be submitted during 2027.
Unlike the Penn State programme, the University of Toronto team is using Molecular Beam Epitaxy (MBE), a technique that enables ultra-pure crystalline structures to be grown one atomic layer at a time under ultra-high-vacuum conditions.
The research also explores gold as a quantum material through electron spin, although it focuses on engineered planar structures rather than nanoclusters. Delta said further technical information remains confidential while intellectual property is being developed.
Professor Harry Ruda, who leads the research programme, commented: “We are encouraged with our experimental work in that it is consistent with our theoretical models for an opportunity to use the material science and quantum properties of gold and other materials with the potential for a platform for more stable and scalable quantum information. We see the opportunity for our structures to potentially be significantly more stable than other approaches. We look forward to the opportunity to collaborate with the team from Penn State as a strong international group under the sponsorship of Delta Gold.”
R. Michael Jones, CEO of Delta Gold said, “Work at both Universities is moving faster than we had expected and it is very exciting to see the parallel approaches moving towards device designs and expanded IP. In the next phase we expect to see even further innovation come from the collaboration and we are hosting a meeting of our two principal investigators here in London in the next few days”.
Expansion Plans Underway
Delta said discussions are progressing on an expanded research programme at Penn State worth up to $6 million over as many as six years. The broader programme is expected to extend beyond quantum information science into areas including quantum sensing and quantum communications.
Alongside this, the company intends to work with the University of Toronto and patent specialists at Haynes Boone to prepare future intellectual property filings as research advances.
Delta also plans to strengthen relationships with leading UK universities as it works towards establishing an international research network spanning North America and the United Kingdom. The company said it also intends to engage with government bodies in the UK, US and Canada while raising awareness among investors.
Focus on Intellectual Property Development
Delta Gold Technologies is building a portfolio of intellectual property centred on nanoscale gold and other advanced materials for use in quantum technologies. Through its sponsored research partnerships with Penn State and the University of Toronto, the company aims to secure additional patents that can support future licensing opportunities, commercial collaborations and the wider development of quantum computing, sensing and communications technologies.
