Single Molecules: Building Blocks for Future Quantum Networks

Quantum computers use qubits to process information, but linking them across long distances requires transmitting quantum information via light. Researchers are exploring single molecules as a promising platform for this task. Single molecules can emit photons—particles of light—that carry quantum information, and they can be precisely placed in nanophotonic structures to enhance light-matter interaction. This approach could enable the creation of quantum repeaters and nodes, essential for building scalable quantum networks. The ability to control single molecules at the nanoscale offers a path toward robust and efficient quantum communication, potentially revolutionizing secure data transfer and distributed quantum computing. As the field advances, single molecules may become the fundamental building blocks of the quantum internet.
