We give a necessary condition for photon state transformations in linear optical setups
preserving the total number of photons. From an analysis of the algebra describing the …

Linear optical systems acting on photon number states produce many interesting evolutions,
but cannot give all the allowed quantum operations on the input state. Using Toponogov's …

The manipulation of the quantum states of light in linear optical systems has multiple
applications in quantum optics and quantum computation. The package QOptCraft gives a …

The evolution of quantum light through linear optical devices can be described by the
scattering matrix S of the system. For linear optical systems with m possible modes, the …

Quantum linear optics is a promising candidate for obtaining a quantum computational
advantage. However, linear optics without post-selection is not powerful enough to produce …

When a quantum state traverses a path, while being under the influence of a gauge
potential, it acquires a geometric phase that is often more than just a scalar quantity. The …

We present the point-coupling Hamiltonian as a model for frequency-independent linear
optical devices acting on propagating optical modes described as a continua of harmonic …

Este TFG presenta un paquete de software que permite automatizar el tratamiento de la
evolución de los estados cuánticos de la luz en dispositivos de óptica lineal. En primer …

In linear optics, modes correspond to a set of fields that are mutually orthogonal, however, in
the nonlinear regime the principle of linear superposition is no longer valid and …

Photon states can be represented using many families of orthogonal fields, such as plane
waves, Laguerre-Gaussian beams, Bessel beams, etc... Here, we show that optical …
