Coherent Spin-Spin Coupling Mediated by Virtual Microwave Photons
We report the coherent coupling of two electron spins at a distance via virtual microwave photons. Each spin is trapped in a silicon double quantum dot at either end of a superconducting resonator, achieving spin-photon couplings up to around gs/2π=40 MHz. As the two spins are brought into resonance with …
