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…
Routing and wavelength assignment in quantum key distribution networks: power control heuristics for quantum-classical multiplexing
Lidia Ruiz, Juan Carlos Garcia-Escartin
As quantum key distribution networks grow in size and complexity, resource assignment has become increasingly important. In passive optical networks without wavelength conversion,…
Finding eigenvectors with a quantum variational algorithm
Juan Carlos Garcia-Escartin
This paper presents a hybrid variational quantum algorithm that finds a random eigenvector of a unitary matrix with a known quantum circuit. The algorithm is based on the SWAP test…
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…
A quantum algorithm for computing the Carmichael function
Juan Carlos Garcia-Escartin
Quantum computers can solve many number theory problems efficiently. Using the efficient quantum algorithm for order finding as an oracle, this paper presents an algorithm that com…
QOptCraft: A Python package for the design and study of linear optical quantum systems
Daniel Gómez Aguado, Vicent Gimeno, Julio José Moyano-Fernández +1
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 collect…
