Fernando Brandao(California Institute of Technology, Pasadena, USA)terrà un seminario dal titolo
“Building a Quantum Computer with Cat Codes ”
abstract:
A comprehensive architectural analysis for a fault-tolerant quantum computer based on cat codes concatenated with outer quantum error-correcting codes is presented. The construction significantly improves upon the fidelity of physical Toffoli gates at very low qubit cost. To achieve even lower overheads, a new magic-state distillation protocol for Toffoli states is devised. For the physical hardware, we propose a system of acoustic resonators coupled to superconducting circuits with a two-dimensional layout. We find that with around 1,000 superconducting circuit components, one could construct a fault-tolerant quantum computer that can run circuits which are intractable for classical supercomputers. Hardware with 32,000 superconducting circuit components, in turn, could simulate the Hubbard model in a regime beyond the reach of classical computing.”Classe di ScienzeIl seminario si terrà in modalità telematica. link per collegarsi all'evento:Valeria GiulianiScuola Normale SuperioreServizio alla Didattica e Allievitel. 050 509260Piazza dei Cavalieri, 756126 PisaE-mail: valeria.giuliani@sns.itE-mail: classi@sns.it
