Riemannian optimization for linear optical problems
Pablo V. Parellada
Many applications of linear optics in quantum science involve searching for some optimal configuration of a multiport interferometer. For example, to find heralded state preparatio…
Finite-size quantum key distribution rates from Rényi entropies using conic optimization
Mariana Navarro, Andrés González Lorente, Pablo V. Parellada +2
Finite-size general security proofs for quantum key distribution based on Rényi entropies have recently been introduced. These approaches are more flexible and provide tighter boun…
Lie algebraic invariants in quantum linear optics
Pablo V. Parellada, Vicent Gimeno i Garcia, Julio José Moyano-Fernández +1
Quantum linear optics without post-selection is not powerful enough to produce any quantum state from a given input state. This limits its utility since some applications require e…
Quantum key distribution rates from non-symmetric conic optimization
Andrés González Lorente, Pablo V. Parellada, Miguel Castillo-Celeita +1
Computing key rates in quantum key distribution (QKD) numerically is essential to unlock more powerful protocols, that use more sophisticated measurement bases or quantum systems o…
No-go theorems for photon state transformations in quantum linear optics
Pablo V. Parellada, Vicent Gimeno i Garcia, Julio-José Moyano-Fernández +1
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 quant…
