Pulsed Electron-Spin Resonance Studies of Atomic Clock Transitions in a Dimer of the Molecular Nanomagnet Cr<sub>7</sub>Mn

ORAL

Abstract

Qubits, or quantum bits, rely on a quantum system that can hold any superposition of two states as opposed to just 0 or 1 as with a classical bit. Various systems have been explored as qubit candidates, including photons, trapped atoms, and both nuclear and electron spins. Our research focuses on constructing two-qubit systems using dimers of molecular nanomagnets (MNMs), a class of magnetic material that can be chemically engineered to achieve various desired attributes. The focus of our current work, dimers of the MNM Cr7Mn, features such an attribute: clock transitions between multiple spin states that increase the lifetime of the quantum state. We present pulsed electron-spin resonance (ESR) studies of dilute Cr7Mn dimers in loop-gap resonators, including spectroscopic exploration of two clock transitions in the dimer as well as progress on implementing two-tone ESR for two-qubit gates.
