Two-Photon Scattering in USC regime
Vanessa Paulisch, Tao Shi, Juan Jose Garcia-Ripoll
In this work we study the scattering of pairs of photons by a two-level system ultrastrongly coupled to a one-dimensional waveguide. We describe this problem using a spin-boson mod…

Quantum metrology with one-dimensional superradiant photonic states
V. Paulisch, M. Perarnau-Llobet, A. González-Tudela +1
Photonic states with large and fixed photon numbers, such as Fock states, enable quantum-enhanced metrology but remain an experimentally elusive resource. A potentially simple, det…

Generation of single and two-mode multiphoton states in waveguide QED
V. Paulisch, H. J. Kimble, J. I. Cirac +1
Single and two-mode multiphoton states are the cornerstone of many quantum technologies, e.g., metrology. In the optical regime these states are generally obtained combining herald…
