Universal entanglement-inspired correlations
Elizabeth Agudelo, Laura Ares, Jan Sperling
Quantum correlations, crucial for the advantage and advancement of quantum science and technology, arise from the impossibility of expressing a quantum state as a tensor product ov…
One-Way Quantum Secure Direct Communication with Choice of Measurement Basis as the Secret
Santiago Bustamante, Boris A. Rodríguez, Elizabeth Agudelo
Motivated by the question of the distinguishability of ensembles described by the same compressed density operator, we propose a model for one-way quantum secure direct communicati…
Quantum Key Distribution with Imperfections: Recent Advances in Security Proofs
Patrick Andriolo, Esteban Vasquez, Elizabeth Agudelo +3
In contrast to classical public-key cryptosystems, where the security of encoded messages relies on on computational assumptions, Quantum Key Distribution (QKD) enables two distant…
Quasiprobabilities from incomplete and overcomplete measurements
Jan Sperling, Laura Ares, Elizabeth Agudelo
We discuss the (re-)construction of quasiprobability representations from generic measurements, including noisy ones. Based on the measurement under study, quasiprobabilities and t…
Photonic Entanglement and Polarization Nonclassicality: Two Manifestations, One Nature
Laura Ares, Nidhin Prasannan, Elizabeth Agudelo +4
We demonstrate in theory and experiment the strict equivalence between nonclassical polarization and the entanglement of indistinguishable photons, thereby unifying these two pheno…
