Strongly hybridized photon–superconducting circuit–magnon states are demonstrated in a microwave cavity using an antiferromagnetic crystal, with nonlinear three-mode coupling enabled by circuit anharmonicity.
- Why it matters: Coherent interactions among more than two quantum systems are needed for tasks like frequency conversion, but observing such multipartite coupling has been elusive.
- What they did: The authors combine an antiferromagnetic crystal, a magnetic-field-resilient superconducting circuit, and a microwave cavity, then use the circuit’s anharmonicity to drive efficient nonlinear interactions among three modes at very different frequencies.
- The result: The observed tripartite hybridization provides a route to quantum interfaces between microwave and terahertz radiation.
