Improved lower bound for the two-way-assisted quantum capacity of the bosonic thermal-loss channel
Matthew Barber, Stefano Pirandola
The bosonic thermal-loss channel is a fundamental model for quantum communication. This Gaussian channel models the transmission of bosonic systems subject to both loss and thermal…

Heuristic Lookahead Distillation Protocol Search
Matthew Barber, Stefano Pirandola
Bipartite qubit entanglement distillation is the process of converting noisy ebits into pure ebits using only local operations and classical communication. This is a core operation…

Optimal Interpolation of Entanglement Purification Protocols
Matthew Barber, Stefano Pirandola
Bipartite entanglement purification is the conversion of copies of weakly entangled pairs shared between two separated parties into a smaller number of strongly entangled shared pa…
