Simultaneous excitation of both spins in a molecular nanomagnet dimer

To make a system of multiple spin qubits out of molecular nanomagnets (MNMs), each spin needs to be separately and simultaneously addressable. The simplest such system is a dimer, where two MNMs are physically and magnetically connected in a single molecule. Performing electron spin resonance (ESR) on both spins at the same time requires both bimodal resonators as well as a spectrometer capable of producing and detecting the necessary multi-frequency pulses. We will report recent work our lab has done to simultaneously excite both spins in an MNM dimer, with an end goal of demonstrating quantum gates in this system.
