Molecular Spins on Layered Magnets for Their Integration in Quantum Cavities

Scalability is a current challenge in quantum technologies [1]. Molecular nanomagnets comprising multiple states, thus hosting more than one spin qubit, and their integration in quantum devices may provide a suitable approach to overcome this challenge [2]. Here we will report in a first step the design of spin qubits and qudits using as molecules polyoxometalate clusters. In a second step, we will explore the deposition and positioning of these molecular spin qubits on layered magnets of the type CrSBr. In a third step and in collaboration with the M. J. Martínez-Pérez team (INMA, Zaragoza), magnonic cavities based on these 2D magnets will be used to study the coupling of the molecular spin qubits with these magnons.<br/><br/>[1] A. Gaita-Ariño, F.
