ALT Graphic showing the experimental setup on the left and the coherence recovery protocol on the right. On the left is a smaller thinner cylinder inside of a larger one that has a green base. A cavity qubit is shown by green arrows pointing left on the outside of the smaller interior cylinder. A chip is placed through a hole in the larger cylinder. On the right is the coherence recovery protocol. Red wavy arrows show an ancilla excitation on the chip, which releases a reset pulse shown by squiggly lines that move toward the green cylinder on the right. There is also a red dashed arrow pointing right that indicates error propagation. A blue meter on the bottom sends an ancilla reset pulse to the chip and a cavity phase correction to the cylinder.
