Analytical Series Expansion for Efficient Gradient Evaluation in Multi-Qubit Optimal Control
Ashutosh Mishra, Elena Lupo, Frank K. Wilhelm +1
Gradient-based quantum optimal control and the theory of operator evolution are rarely discussed together. In this Letter, we bridge this gap by showing that the gradient of the ti…

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…
