A method for the numerical analysis of hybrid lumped-distributed superconducting quantum circuits

Simona Zaccaria, Antonio Gnudi·Sep 3, 2025

We present a method for the numerical analysis of superconducting quantum circuits combining lumped elements, either linear or non-linear (i.e.~Josephson junctions), and distributed coplanar waveguide (CPW) structures. CPW transmission lines and mult...

The Structure and Interpretation of Quantum Programs I: Foundations

D. Wakeham·Sep 3, 2025

Qubits are a great way to build a quantum computer, but a limited way to program one. We replace the usual"states and gates"formalism with a"props and ops"(propositions and operators) model in which (a) the C*-algebra of observables supplies the synt...
