Could the Quantum Internet Be Comprised of Molecular Spins with Tunable Optical Interfaces?
Daniel W. Laorenza, Danna E. Freedman
Abstract
quantum information across the world, forming the basis of the quantum Internet. Achieving this lofty goal will require scalable and tunable materials that allow for cross-platform interconnections. Solution-processable molecular systems designed from the ground up are poised to introduce the necessary tunability to meet these needs. In this Perspective, we describe the components of a quantum network, outline the criteria to create molecular systems suitable for networking applications, and discuss the pathway to generate spin-photon entanglement, a first step toward remote entanglement between molecular spins in a network. We also describe some initial steps to optimize molecular spins for potential integration into quantum networks as readily deployable qubits in network nodes. Throughout this Perspective, we highlight the tremendous potential of molecular systems for the quantum Internet and illustrate openings for chemists in this nascent field.
