Molecular Magnetocalorics for Quantum Information Science
ORAL · Invited
Abstract
Next-generation quantum technologies demand cryogenic environments where thermal noise is minimized and quantum states are precisely controlled. Synthetic chemistry provides powerful means to design molecular materials whose properties are exploitable not only for spin-based quantum computing but also for caloric cooling. This presentation highlights recent breakthroughs in molecular magnetocalorics, showcasing materials that achieve remarkable low-temperature cooling [A. S. Manwell, et al., J. Am. Chem. Soc. 147, 7597 (2025), 10.1021/jacs.4c17003; S. P. K. Panguluri, et al., J. Am. Chem. Soc. (2025), 10.1021/jacs.5c13048]. It further demonstrates how a spin qubit can be coupled to a nearby spin center acting as a local molecular refrigerator. By uniting spin-based quantum control and caloric refrigeration, this work paves the way toward self-cooling spin quantum processors where both functionalities coexist at the molecular scale [E. Palacios, et al., Adv. Mater., e11061 (2025), 10.1002/adma.202511061].
