Computational distinguishability of degradable and antidegradable channels
Bill Rosgen
A channel is degradable if there exists a second channel that maps the output state of the channel to the environment state. These channels satisfy the property that the output sta…

Testing non-isometry is QMA-complete
Bill Rosgen
Determining the worst-case uncertainty added by a quantum circuit is shown to be computationally intractable. This is the problem of detecting when a quantum channel implemented as…
