On the number of words of letters with a three-letter alphabet
Pablo Serra
In this paper we address the well-known problem of counting the number of -letter words that can be formed from a three-letter alphabet by decomposing it into four possible cas…

Perfect, Pretty Good and Optimized Quantum State Transfer in Transmon qubit chains
Pablo Serra, Alejandro Ferrón, Omar Osenda
Chains of transmon qubits are considered promising systems to implement different quantum information tasks. In particular as channels that perform high-quality quantum state trans…

The scaling law of the arrival time of spin systems that present pretty good transmission
Pablo Serra, Alejandro Ferrón, Omar Osenda
The pretty good transmission scenario implies that the probability of sending one excitation from one extreme of a spin chain to the other can reach values arbitrarily close to the…
