Generation of higher dimensional entangled states in quantum Rabi systems
Generation of higher dimensional entangled states in quantum Rabi systems
We present protocols for the generation of high-dimensional entangled states of anharmonic oscillators by means of coherent manipulation of light-matter systems in the ultrastrong coupling regime. Our protocols consider a pair of ultrastrong coupled qubit-cavity systems, each coupled to an ancilla qubit, and combine classical pulses plus the selection rules …
