US and UK Back Eight Teams to Engineer Molecular Quantum States

Eight research teams from the US and UK have received a total of $10 million to address a central challenge in quantum science: keeping quantum states stable in complex molecular systems. The joint program, confirmed by the US National Science Foundation (NSF) and UK Research and Innovation (UKRI) in September 2026, aims to speed up chemistry research that could lay the groundwork for future quantum information technologies. The Quantum Insider reported the same funding figures and timeline.

Custom molecular qubits

The focus of the program is on creating and controlling molecules that can act as qubits-the basic units of quantum information. Unlike solid-state or photonic qubits, molecular qubits can be tuned in many ways, but their quantum states are easily disturbed by their surroundings. The funded teams will work on designing molecules that can keep quantum coherence, entanglement, and superposition intact, even when exposed to heat and other environmental factors. This matches the NSF's goal to develop molecular systems that can store and protect quantum information from outside influences, including temperature changes-a problem that sits between chemistry and quantum physics, as discussed in recent Nature publications.

The technical work includes developing spin qubits at the molecular scale, building chemical structures that shield quantum states from decoherence, and modeling how quantum information moves during chemical reactions. These projects aim to tackle environmental decoherence, which is still a major obstacle for practical quantum computing and sensing. The NSF says teams will "demonstrate, control, and quantitatively describe" quantum effects in molecules and chemical reactions, an area that institutions like MIT and Stanford have also called crucial for the next wave of quantum technology.

Funding and collaboration

The program is funded by $5 million from the NSF Directorate for Mathematical and Physical Sciences and £3.7 million (about $5 million) from UKRI's Engineering and Physical Sciences Research Council (EPSRC). This builds on earlier investments announced in 2025. The funding will be split among eight teams, pairing labs in the US and UK to combine experimental and theoretical strengths. In the US, principal investigators at nine universities across nine states will take part, including at least one institution supported through the NSF Established Program to Stimulate Competitive Research (EPSCoR), which aims to broaden participation in advanced science.

This is the second phase of NSF-EPSRC quantum chemistry funding, following an initial $10 million round in 2025. The collaboration fits with international research partnership goals set out in the June 2026 Executive Order on quantum innovation. The NSF also notes that the program will offer training and career opportunities for students and early-career researchers, supporting both research and workforce development.

Technical and policy context

Quantum information science at the molecular level requires precise control over quantum states that are easily disrupted. The funded projects will try to engineer molecules with specific spin properties and stable quantum coherence, with the goal of creating building blocks for quantum sensors, memories, and processors. Reliable quantum information transfer in chemical systems could open new paths for quantum simulation and computing, but the technical hurdles are significant. Research at CERN and the Max Planck Society has shown the importance of isolating quantum systems from environmental noise, a principle now being applied to molecules.

Recent progress in quantum hardware has highlighted the need for better interconnects, lower error rates, and improved shielding from the environment. As reported earlier, scaling up quantum systems requires new device designs as well as solutions for wiring and thermal management. The molecular approach adds complexity, since chemical variability and environmental coupling introduce more sources of noise and error. Peer-reviewed studies in Science and PNAS have shown that even small changes in molecular structure can greatly affect coherence times, underlining the need for careful experimental controls.

Engineering limits and next steps

While molecular qubits hold promise, building practical devices is still a long way off. Protecting quantum states from decoherence in complex chemical environments is an open problem. The funded teams will need to show that their molecules can keep coherence and entanglement long enough for useful quantum operations, and that these properties are consistent across different samples and conditions. Metrics like coherence time distributions and error rates will be key for tracking progress, with standards modeled after protocols at places like Harvard and MIT.

Moving forward will require advances in both synthetic chemistry and quantum measurement. Integrating molecular qubits into larger quantum systems, and making sure they work with existing control and readout tools, will be important milestones. This round of funding is meant to help build the scientific and technical base needed for molecular quantum information science to move beyond early-stage experiments. The NSF and UKRI have also said the program will train the next generation of quantum scientists, giving students and early-career researchers hands-on experience and career support.

Quantum coherence allows a quantum system to exist in a superposition of states, making interference and entanglement possible. In molecules, coherence is usually limited by interactions with the environment, which cause decoherence and destroy quantum information. Engineering molecules to resist decoherence means carefully controlling their structure, spin, and chemical surroundings. Success here could lead to new types of quantum devices, but the main challenge is balancing tunability with stability under real lab and operating conditions.
