Telecloning of qudits via partially entangled states
Gabriel Araneda, Nataly Cisternas, Aldo Delgado
We study the process of quantum telecloning of -dimensional pure quantum states using partially entangled pure states as quantum channel. This process efficiently mixes optimal…
Experimental nonlocality-based randomness generation with non-projective measurements
S. Gómez, A. Mattar, E. S. Gómez +4
We report on an optical setup generating more than one bit of randomness from one entangled bit (i.e. a maximally entangled state of two-qubits). The amount of randomness is certif…
Certifying an irreducible 1024-dimensional photonic state using refined dimension witnesses
Edgar A. Aguilar, Máté Farkas, Daniel Martínez +7
We report on a new class of dimension witnesses, based on quantum random access codes, which are a function of the recorded statistics and that have different bounds for all possib…
Quantum localized states in photonic flat-band lattices
Santiago Rojas-Rojas, Luis Morales-Inostroza, Rodrigo A. Vicencio +1
The localization of light in flat-band lattices has been recently proposed and experimentally demonstrated in several configurations, assuming a classical description of light. Her…
Proposal for Automated Operations for Single-Photon Multipath Qudits
Roberto D. Baldijão, Gilberto F. Borges, Breno Marques +3
We propose a method for implementing automated state transformations on single-photon multipath qudits encoded in a one-dimensional transverse spatial domain. It relies on transfer…
Experimental minimum-error quantum-state discrimination in high dimensions
M. A. Solís-Prosser, M. F. Fernandes, O. Jiménez +2
Quantum mechanics forbids perfect discrimination among nonorthogonal states through a single shot measurement. To optimize this task, many strategies were devised that later became…
