Shaping an Itinerant Quantum Field into a Multimode Squeezed Vacuum by Dissipation
Diego Porras, Juan José García‐Ripoll · Physical Review Letters · 2012
We show that inducing sidebands in the emission of a single emitter into a one-dimensional waveguide, together with a dissipative repumping process, a photon field is cooled down to a multimode squeezed vacuum. Our method does not require being in the strong coupling regime, works with a continuum of propagating field modes, and leads to sources of tunable multimode squeezed light in circuit-QED systems.
