Gradient-based quantum optimal control meets feedback.
Florian MarquardtFor friends of #QuantumControl and #QuantumTechnologies: Out now in #PRXQuantum, our newest paper.
How do you combine feedback and gradient-based optimization of control strategies --- something that is very useful for optimizing quantum error correction and many other important tasks? "feedback GRAPE" is our answer, as a new technique:

A generalization of the Shor and Steane constructions allows for measurement of select logical Pauli operators in error-correcting codes with reduced time and space overhead and opens the door to fault-tolerant implementations of logical gates.
