Bachelor's thesis, Harvard College.28410981https://nrs.harvard.edu/URN-3:HUL.INSTREPOS:37368577Quantum repeaters, and the quantum communication they enable, are as vital to the efficient use of quantum computers as the internet is to current computing. The Lukin Group has developed a repeater architecture using Silicon Vacancy Centers in diamond, and members have used it to experimentally demonstrate single-qubit communication. Currently, though, its circuit depth and two-qubit functionality are limited by heating due to microwave driving from gold coplanar waveguides (CPW) atop the diamond’s surface. To break through this barrier, superconducting CPW’s, which do not dissipate heat, have been developed.application/pdfenCPWNetworkQuantumRepeaterSuperconductingPhysicsThesis or Dissertation2021-07-19
