Quantum Materials & Technologies
Quantum science is transforming our understanding of material behaviours, and enabling the development of technologies with the potential to revolutionise computing, sensing, communications and advanced electronics.
From superconductors to low-dimensional systems, researchers are continuously exploring novel materials systems capable of controlling and exploiting quantum phenomena. At the centre of these advances are quantum materials – materials whose electronic, magnetic and optical properties are governed by quantum mechanical effects. Understanding the relationship between material structure and quantum behaviour enables researchers to design, fabricate and characterise the materials that underpin next-generation quantum devices.
As research moves from fundamental discoveries towards practical applications, the demand for high-purity materials, specialised substrates and advanced thin-film deposition materials continues to grow. Material purity, crystalline structure and surface quality are critical to innovation in the field – and this is exactly where a specialist materials supplier adds the most value.
PI-KEM supplies researchers working at the frontier of quantum technology with the high-purity substrates,sputtering targets, evaporation sources and speciality compounds needed to grow, deposit and pattern quantum materials.
Quantum Materials at a Glance
Quantum materials are materials whose large-scale properties are governed by microscopic quantum mechanical behaviours. The quantum effects don't average out as they do in most ordinary materials; instead, they become amplified through the collective interactions of many particles, leading to macroscopic quantum properties.
This gives rise to effects such as wave-particle duality, quantum coherence, entanglement, and quantum topology.
Because of these collective quantum effects, quantum materials can exhibit valuable properties such as:
- Superconductivity – zero electrical resistance and magnetic field expulsion below a critical temperature.
- Topological insulation – surface conduction without bulk conduction.
- Quantum coherence – electrons behave like coherent waves over relatively large distances.
- Quantum phase transitions – abrupt changes between different states of matter (e.g. from magnetic to non-magnetic or from insulating to superconducting).
These materials are important both scientifically and technologically because they expand our understanding of how matter behaves, and enable future technologies including quantum computers, ultra-sensitive sensors, low-power electronics, and more efficient energy systems.
The State of Quantum Research
In early 2026, the UK government announced a £2 billion programme for quantum technology innovation, reflecting the importance of continued research in this field. The scope of quantum materials and technologies is vast, however some of the current research focuses can be found below:
- Quantum Dots & Nanostructures – Quantum dots and other semiconductor nanostructures exhibit unique optical and electronic properties arising from quantum confinement. They are being investigated for applications including single-photon generation, quantum communication, advanced photonics and quantum information technologies.
- Spintronics – By exploiting the spin of electrons in addition to their charge, spintronic materials offer new approaches to information processing, data storage and quantum sensing.
- Topological Materials – Topological insulators and topological superconductors have surface states that are protected by symmetry, making them attractive for "topological qubits" that are inherently more resistant to local noise. Current research focuses on engineering clean interfaces between topological and conventional superconductors.
- Low-Dimensional Materials – Graphene, hexagonal boron nitride and other 2D materials can be stacked into heterostructures with tuneable electronic, spin and optical properties that are robust against external disturbances. These systems are attracting interest for next-generation electronics, quantum devices and fundamental studies of quantum phenomena.
- Superconducting Circuits & Qubits – Superconducting circuits are thin-film circuits patterned onto ultra-high-purity substrates. By engineering these circuits with components like Josephson junctions, they can form artificial atoms with discrete energy levels, which are used as qubits. These qubits can exist in superpositions of states and be entangled, making them one of the leading platforms for building quantum computers.
Challenges Facing Quantum Materials Research
Material Purity & Defect Density – Quantum coherence is extremely sensitive to defects and impurities in the host material. Achieving the ultra-high purity grades needed for superconducting circuits or 2D material growth substrates is essential in the field. Purity requirements continue to tighten as device architectures scale up.
Substrate & Interface Engineering – Many of the promising quantum devices rely on atomically clean interfaces between dissimilar materials. Even minor surface roughness, contamination, strain or chemical reactivity at these interfaces can introduce mechanisms that limit coherence.
Scalability from Lab to Production – Most quantum materials are currently produced as small, irregular batches of bespoke-grown materials. While this is sufficient for fundamental research, it is a long way from the large-scale, reproducible manufacturing processes needed for commercial quantum technologies. Research is increasingly focused on scalable thin-film growth and deposition routes that can replicate the performance of lab-scale materials.
To support this, PI-KEM can supply ultra-high purity substrates, sputtering targets and evaporation sources, novel crystal compositions and dopant levels, and access to a broad supplier network for hard-to-source quantum-grade materials.
