Quantum outage probability for time-varying quantum channels
Josu Etxezarreta Martinez, Patricio Fuentes, Pedro Crespo +1
Recent experimental studies have shown that the relaxation time, , and the dephasing time, , of superconducting qubits fluctuate considerably over time. Time-varying quan…

On the logical error rate of sparse quantum codes
Patricio Fuentes, Josu Etxezarreta Martinez, Pedro M. Crespo +1
The quantum paradigm presents a phenomenon known as degeneracy that should improve the performance of quantum error correcting codes. However, the effects of this mechanism are som…
