Proposal to Generate and Characterize Quantum Entanglement using Coupled Metamaterial Resonators

Entanglement is an underlying principle in quantum physics. Undoubtedly, the consequences of the correlations observed between measurements in spatially separated entangled systems has had a profound effect on our view of local realism of the world (EPR, Bell etc.). Using a left-handed metamaterial coupled to a nanomechanical resonator, we propose a new procedure to couple multiple microwave resonant modes and investigate entanglement in these limits. These investigation allow for the possibility to develop new techniques for characterizing entanglement in multi-mode systems. The potential of using these circuits in QED architectures is discussed.
