- Cavity electrodynamics of van der Waals heterostructuresNature Physics, Published online: 20 October 2025; doi:10.1038/s41567-025-03064-8 Integrating an electronic device with a cavity can cause the electrons to couple to photons strongly enough to form hybrid modes. Now, the cavity effects induced by intrinsic graphite gates are shown to modify the low-energy properties of graphene.
- Demonstration of dynamic surface codesNature Physics, Published online: 17 October 2025; doi:10.1038/s41567-025-03070-w Typical quantum error correcting codes assign fixed roles to the underlying physical qubits. Now the performance benefits of alternative, dynamic error correction schemes have been demonstrated on a superconducting quantum processor.
