Web4. Eigenvalues and eigenstates. Each operator Y^ has a set of eigenvalues y which are the possible values you can get on doing a measurement of Y. Any measurement of Y must yield one of the eigenvalues. Each eigenvalue y is associated with an eigenstate ˚ y(x), which is the state for which the value of Yis exactly y, with no uncertainty.

WebApr 13, 2024 · For correlated two-photon scattering in the waveguide quantum electrodynamics system, scattering eigenstates are constructed by imposing an open boundary condition and setting the incident state as a free plane wave. A photon-photon bound state emerges which is necessary for a completeness check upon the …
WebMar 29, 2024 · Consider the eigenvalue equation for A ^, i.e. A ^ ψ = λ ψ. If we apply A ^ again we get the equation A ^ 2 ψ = λ 2 ψ. But note from the definition of A ^, i.e. its action on the basis, that A ^ 2 = Id. Thus the previous equation gives us. λ 2 = 1 → λ = ± 1. So we have found the eigen values pretty easily. The question remains as to ... WebApr 24, 2015 · Here, we study the simulation of quantum spin systems under an external magnetic field using linear optics. We use entangled photon pairs and apply various variable single-qubit gates and a two-qubit gate to them. We are able to generate the eigenstates of the XY Hamiltonian for two spins, including the ground state.
