| Sumario: | Quantum interactions going hybrid: ferromagnetically mediated coupling Hybrid architectures that combine materials and devices with widely different properties promise to be at the forefront of scalable quantum systems by unlocking access to more than the simple sum of their parts. A team led by David Awschalom at the University of Chicago has now revealed the possibility of using collective spin oscillations in a ferromagnet to mediate long-range, coherent interactions between a microwave source and spin qubits confined in diamond nanoparticles. The strong surface confinement of the ferromagnet excitations and their slow decay result in an effective amplification of the source field over hundreds of micrometers at ambient conditions. This effect can extend the capabilities of solid state qubits for quantum information and nanoscale quantum sensing applications. |
