“…Quantum information science (QIS) takes advantage of materials that can obtain a quantum superposition state, which is of interest for quantum computing, quantum cryptography, and quantum sensing. − These efforts rely on the development of the quantum bit, or qubit, , and numerous qubit candidates have been studied, including trapped ions, quantum dots, and nitrogen-vacancy centers in diamond. − Molecules with unpaired electrons can also function as qubits and have the potential of being designed and tuned using synthetic and physical chemical principles. ,− Furthermore, it is now increasingly possible to design solid-state molecular assemblies to order qubits into extended arrays with emergent properties. Several types of supramolecular assemblies can incorporate molecular spins, including metal–organic frameworks (MOFs) ,− or two-dimensional polymers (2DPs) . The promise of these approaches is to tune qubit coupling, and especially their spin–lattice ( T 1 ) and spin–spin ( T m ) relaxation times …”
