A linear-time benchmarking tool for generalized surface codes
Nicolas Delfosse, Pavithran Iyer, David Poulin
Quantum information processors need to be protected against errors and faults. One of the most widely considered fault-tolerant architecture is based on surface codes. While the ge…
Equivalence between contextuality and negativity of the Wigner function for qudits
Nicolas Delfosse, Cihan Okay, Juan Bermejo-Vega +2
Contextuality and negativity of the Wigner function are two notions of non-classicality for quantum systems. Howard, Wallman, Veitch and Emerson proved recently that these two noti…
Contextuality as a resource for models of quantum computation on qubits
Juan Bermejo-Vega, Nicolas Delfosse, Dan E. Browne +2
A central question in quantum computation is to identify the resources that are responsible for quantum speed-up. Quantum contextuality has been recently shown to be a resource for…
Generalized surface codes and packing of logical qubits
Nicolas Delfosse, Pavithran Iyer, David Poulin
We consider a notion of relative homology (and cohomology) for surfaces with two types of boundaries. Using this tool, we study a generalization of Kitaev's code based on surfaces…
