Understand

Quantum information processing is in real systems often limited by dissipation, stemming from remaining uncontrolled interaction with microscopic degrees of freedom.

Given recent experimental progress, we consider weak dissipation, resulting in a small error probability per operation.
Here, we find a simple formula for the fidelity reduction of any desired quantum operation.
Interestingly, this reduction is independent of the specific operation; it depends only on the operation time and the dissipation.
