09:05-09:35 No small matter: atomistic modelling insights into energy materials

Further breakthroughs in materials for energy-related technologies such as lithium batteries and solar cells require advances in new compositions and underpinning materials science. Indeed, a greater fundamental understanding and optimisation of energy materials require nano-scale characterisation of their structural, ion transport and interface behaviour. In this context, atomistic modelling has been a powerful approach for investigating these properties, which have relied on advances in high end supercomputers. This presentation will describe such studies in two principal areas with an outline of what quantum computing can contribute to this field; (i) new high energy density cathode materials for lithium-ion EV batteries; (ii) halide perovskite materials for next-generation solar cells and optoelectronics.

11:00-11:30 Computing response properties of materials: bottlenecks and challenges

Condensed matter theory makes a junction between the N-body problem, materials science and new questions raised by ever improving experiments. In particular, the response of matter excited by radiation such as light is often dominated by many-body effects, implying that the response of all electrons or nuclei cannot be understood as the sum of individual responses, not even qualitatively. The quantum nature of electrons constitutes an additional difficulty and source of surprises. Different strategies exist to deal with this problem at least approximately. These range from clever reformulations, for example in terms of functionals, to the use of model systems that can be studied over wide parameter ranges, and progress is based on advances of theory, algorithms, and new computational paradigms. In this talk, Dr Reining will explore some current challenges in excited states and spectroscopy of materials that push today’s approaches to their limits, and will open a discussion about bottlenecks in the various strategies that quantum computing could potentially overcome.

11:45-12:15 Quantum embedding methods for simulations of materials on quantum computer

We discuss computational frameworks to carry out electronic structure calculations of solids on noisy intermediate scale quantum computers [1,2] using embedding theories [3], and we give examples for a specific class of materials, i.e., spin defects in solids. These are promising systems to build future quantum technologies, e.g., computers, sensors and devices for quantum communications. We also present a hybrid quantum- classical quantum monte carlo algorithm (QC-QMC) scheme [4] applied to both spin-defects in solids and molecules, which removes a pre-existing classical exponential bottleneck in post-processing; we show from experiments on quantum hardware that the QC-QMC algorithm is inherently noise robust. Although quantum simulations on quantum architectures are in their infancy and still face considerable challenges, promising results appear to be within reach.

13:30-14:00 Bridging scales: multi-scale modelling for next-generation materials innovation

The materials discovery landscape is undergoing a profound transformation driven by advances in multi-scale modelling approaches that connect atomic-level phenomena to real-world performance. This presentation examines the challenges and opportunities in integrating computational methods across different length and time scales to accelerate materials innovation. We highlight how modern computational approaches are evolving beyond isolated simulations to provide comprehensive frameworks that capture the complexity of real-world materials behaviour, from electronic structure to macroscopic properties. The presentation discusses how artificial intelligence and quantum computing can be strategically integrated with classical methods to overcome current computational bottlenecks and enhance predictive capabilities. Through detailed case studies in three high-impact domains—carbon capture technologies, pharmaceutical development, and corrosion-resistant materials—we demonstrate how multi-scale modelling approaches are solving previously intractable challenges and opening new pathways for innovation. As quantum computing technology matures, we emphasise the critical importance of developing robust integration infrastructure and middleware solutions that effectively connect quantum capabilities with established classical systems to deliver practical business value. This presentation argues that the future of materials discovery depends not on revolutionary advances in any single computational technique, but on our ability to seamlessly integrate complementary approaches across multiple scales, ultimately transforming how we discover, optimise, and deploy advanced materials for society's most pressing challenges.

15:30-16:00 Quantum computation and optimisation using neutral atom arrays

Neutral atoms have emerged as a powerful and scalable platform for quantum computing, offering the ability to generate large numbers of identical and high quality qubits in reconfigurable arrays. By coupling atom to highly excited Rydberg states with strong, long-range dipole-dipole interactions it is possible to perform high-fidelity two and multi-qubit gate operations, or to natively implement classical graph optimisation problems, highlighting the versatility for performing both analogue and digital quantum computing.

In this talk we will present work at Strathclyde focused on developing large-scale system for quantum computing and optimisation, including demonstration of high fidelity single qubit gate operations on up to 225 qubits with errors below the threshold for fault tolerance using a non-destructive readout technique, as well as initial results from performing weighted graph optimisation using programmable local light-shifts across the atomy array. This provides a route to embedding a wider class of problems including quadratic unconstrained binary optimisation (QuBO) and integer factorisation, and extension to native implementations of graph colouring.

Alongside progress towards large-scale analogue optimisation, we will present a new cryogenic dual-species setup targeting fault-tolerant digital computation using quantum error-correction. This approach offers suppression of mid-circuit readout errors due to use of atoms of different species, and will provide a versatile test-bed for prototyping and benchmarking performance and scalability of recently proposed quantum low-density parity check codes.

09:45-10:15 From promise to practice: the challenges in finding quantum computing applications

Quantum computing has long been heralded as a revolutionary force poised to transform numerous industries. Early predictions by consulting firms such as McKinsey and BCG suggested dramatic impacts across pharma, chemistry, materials science and related sectors. In pharmaceuticals specifically, quantum computing was expected to revolutionise drug discovery and enhance molecular simulations, significantly reducing research and development timelines and associated costs. Yet, despite substantial investments, these optimistic forecasts have not yet materialised into tangible industrial benefits.

While quantum algorithms such as Quantum Phase Estimation (QPE) theoretically provide ground-breaking computational capabilities - enabling calculations beyond the reach of classical computers - practical industrial applications remain elusive. Accurate quantum calculations alone do not automatically enable faster drug discovery or improved material designs. Industries require quantum computing solutions that deliver clear, substantial, and cost-effective advantages, sufficient to justify significant investment and substantial organisational changes. This challenge is intensified by the continuing improvements and accumulated expertise of classical computational methods and recent advancements in artificial intelligence.

Effectively bridging this gap demands sustained collaboration, realistic expectation setting, and integrated end-to-end methodologies capable of delivering genuinely beneficial outcomes. Achieving industrial impact with quantum computing is less a question of theoretical promise and more one of systematically addressing industry-specific needs through targeted, innovative approaches.

11:45-12:15 Towards materials and chemistry simulation on near-term quantum devices

At Phasecraft, they are developing and implementing methods that will lead to practical application on noisy near-term and early fault-tolerant quantum devices. Performing molecule and material simulations on such devices requires deep understanding of the physics of the problem at hand in combination with efficient representation and encoding of the problem on a device, to not only maximise use of limited resources, but also to provide accurate results ultimately aiming to outperform classical computation on problems of interest.

Using examples from some recent consortia based programmes in materials and human health, the talk will introduce some of the considerations of representing and implementing your electronic structure problem on a quantum device. Following which, some of the key ideas in practical workflows and results from hybrid-classical algorithms will be presented. A brief discussion of open challenges and future directions will conclude the presentation.

14:15-14:45 Near-term quantum algorithms for many-body physics and material science: a path towards quantum utility

Quantum computing is emerging as a transformative paradigm, offering solutions to problems that are intractable for classical computers. This potential is particularly pronounced in many-body physics, quantum chemistry, and materials sciences, where the exponential complexity of classical methods can be efficiently addressed by quantum computing. Recent advancements in quantum technologies indicate that significant progress in these fields is achievable even with near-term noisy quantum computers. To realise this potential, noise-resilient quantum algorithms and error mitigation strategies have been developed and integrated into hybrid quantum-classical workflows, fostering a productive interplay between quantum and classical computational platforms.

In this talk, Dr Tavernelli will present recent advancements in quantum algorithms for many-body physics and quantum chemistry, emphasising their relevance to near-term quantum computing. Key topics include error mitigation strategies critical for achieving accurate, utility-scale results, such as probabilistic error cancellation (PEC) and tensor network-based error mitigation (TEM). Additionally, embedding techniques that integrate quantum electronic structure methods with density functional theory will be discussed and dynamical mean field theory, enabling efficient problem partitioning while maintaining high accuracy.

These methods will be demonstrated through case studies on the computation of ground and excited-state properties in molecules and solids, as well as simulations of quantum dynamics.

15:30-16:00 From noisy measurements to physical spectra - extension, continuation, and projection techniques for response functions

Response functions of quantum systems, such as electron Green's functions, magnetic, or charge susceptibilities, describe the response of a system to an external perturbation. They are the central objects of interest in quantum computing applications for molecules and materials. Response functions are intrinsically causal. In equilibrium and in steady-state systems, they correspond to a positive spectral function in the frequency domain. Since response functions define an inner product on a Hilbert space and thereby induce a positive definite function, the properties of this function can be used to reduce noise in measured data and to construct positive definite extensions for data known on finite time intervals, which are then guaranteed to correspond to positive spectra.
