Majorization theory approach to the Gaussian channel minimum entropy conjecture
Raul Garcia-Patron, Carlos Navarrete-Benlloch, Seth Lloyd +2
A longstanding open problem in quantum information theory is to find the classical capacity of an optical communication link, modeled as a Gaussian bosonic channel. It has been con…
Gaussian Quantum Information
Christian Weedbrook, Stefano Pirandola, Raul Garcia-Patron +4
The science of quantum information has arisen over the last two decades centered on the manipulation of individual quanta of information, known as quantum bits or qubits. Quantum c…
A reply to "Problems with modelling closed timelike curves as post-selected teleportation"
Seth Lloyd, Lorenzo Maccone, Raul Garcia-Patron +8
In arXiv:1107.4675 Ralph uses our post-selection model of closed timelike curves (P-CTC) to construct an "unproven-theorem" paradox, and claims that this voids our argument that P-…
Percolation of secret correlations in a network
Anthony Leverrier, Raul Garcia-Patron
In this work, we explore the analogy between entanglement and secret classical correlations in the context of large networks, more precisely the question of percolation of secret c…
