Deterministic Quantum Defects in Hexagonal Boron Nitride for Room-Temperature Quantum Sensing

Research question
Owing to their high coherence and atomic size, solid-state spin qubits offer strong potential for next-generation quantum technologies, including quantum computing, communication, imagining and sensing. Quantum defects in solids enable highly sensitive, atomic-scale measurements of magnetic, electric, strain, and temperature fields at room temperature, making them powerful probes of local environments.

We aim to create deterministically engineered quantum defects in hexagonal boron nitride (hBN) using ion implantation, laser  defect activation, and lithographic masking to create defect arrays. These will be characterized through advanced quantum coherence measurements and guided by theoretical modeling to identify their optical and spin properties.

Sustainability aspects
This project supports sustainable development by enabling nanoscale quantum sensors for applications in medical diagnostics, environmental monitoring, and industrial quality control. hBN-based defects allow room-temperature, high-resolution sensing, improving healthcare (SDG 3), innovation and industry (SDG 9), and resource efficiency (SDG 12). The use of abundant, non-toxic materials and low material volumes reduces waste, while deterministic defect engineering minimizes unnecessary processing. Although energy savings from room-temperature operation are beneficial, the main impact lies in providing precise, resource-efficient sensing technologies for long-term sustainability.
