Quantum Error Detection I: Statement of the Problem
read the original abstract
I. This paper is devoted to the problem of error detection with quantum codes. In the first part we examine possible problem settings for quantum error detection. Our goal is to derive a functional that describes the probability of undetected error under natural physical assumptions concerning transmission with error detection over the depolarizing channel. We discuss possible transmission protocols with stabilizer and unrestricted quantum codes. The set of results proved in Part I shows that in all the cases considered the average probability of undetected error for a given code is essentially given by one and the same function of its weight enumerators. This enables us to give a consistent definition of the undetected error event.

Spectral properties and coding transitions of Haar-random quantum codes
Haar-random quantum codes lose correctability exactly at the hashing bound, and the spectral band structure predicts a higher detection threshold for postselected error correction.
