Engineered broadband Purcell protection using a shared -filter for multiplexed superconducting qubits
Samuel D. Escribano, Yael Kriheli, Samuel Goldstein +2
We propose a broadband Purcell-protection scheme based on a single shared filter integrated directly into the feedline, enabling simultaneous protection of multiple qubits in a com…

A proposal for charge basis tomography of superconducting qubits
Elena Lupo, Daniel Long, Daniel Dahan +4
We introduce a general protocol for obtaining the charge basis density matrix of a superconducting quantum circuit. Inspired by cavity state tomography, our protocol combines Josep…
