Electric control of spin for molecule-based quantum technologies

Traditional information technology faces capacity and energy limits, necessitating a paradigm shift to quantum-based systems. Unpaired electron spins, such as those in magnetic molecules, offer promising platforms for qubits due to their quantum nature and ability to form superpositions. Molecules provide unique advantages, including chemical tunability and surface processing for individual addressing. However, magnetic fields are unsuitable for precise spin control, unlike electric fields, which are energy-efficient and spatially localized. We recently demonstrated electric field modulation of magnetic exchange using EPR spectroscopy (Nature Materials 2019). With ELECOS, we aim to achieve coherent control of molecular qubits and quantum gates via electric fields, advancing molecule-based quantum computing.
