Microwaves have enabled numerous classical technologies, in part because they propagate through air with little energy loss. Using novel approaches, we are working to demonstrate the generation of two or more entangled microwave photons. The photons themselves can be used for quantum communication or can be used on-chip to entangle separated parts of a quantum processor. We are also working toward other milestones, such as using microwaves to demonstrate remote entanglement of qubits. One of our goals is to boost capability for quantum communication, which can lead to a next-generation Internet, and which is a focal point in the quantum space race that has emerged with other nations. We also expect our work to advance the field of quantum computing.
