Coherent state fock basis

WebThe full-density matrix of the qubit state–dependent itinerant microwave field is reconstructed with the maximum likelihood quantum state estimation in Fock basis (38–40). Considering the fact that the ideal states are Greenberger-Horne-Zeilinger–type entangled coherent states (see Eq. 2 ), the density matrices are plotted in the cat ... WebFeb 28, 2024 · However, coherent states are quantum states and measurement in a Fock basis is a quantum measurement. Here, we will argue that by careful construction of optical experiments, coherent state sources, linear optics, and photon detection can reconstruct the statistics of any multi-photon experiment.
