Amosov and Sergey N. Filippov, 000005 | Spectral properties of reduced fermionic density operators and parity 000006 | superselection rule, Quantum Information Processing16,2 (2017). 000007 | https://arxiv.org/abs/1512.01828 000008 | https://doi.org/10.1007/s11128-016-1467-9 000009 | 000010 | The authors define the particle-reduction operation as 000011 | Phi(rho)=sum_i a_i rho a_i^dagger. On a fixed n-particle sector its trace 000012 | is n, so division by n gives the particle-loss channel. This supports 000013 | the established mathematical reading of the exterior channel used here. 000014 | The identification with the specific Petersen response and the actual 000015 | TFPT E8 source is computed separately in our exact source checks. 000016 | 000017 | Marius Lemm and Mark M. Wilde, 000018 | Information-theoretic limitations on approximate quantum cloning and 000019 | broadcasting, Physical Review A96,012304 (2017). 000020 | https://arxiv.org/abs/1608.07569 000021 | https://doi.org/10.1103/PhysRevA.96.012304 000022 | 000023 | The paper treats antisymmetric particle subspaces, particle-loss partial 000024 | traces and their relation to recovery/cloning maps. It supplies context 000025 | for the known fermionic operation. It is not evidence that P1 selects 000026 | the event record, source insertion, physical dynamics or initial state. 000027 | 000028 | These are primary research sources. Their use does not make the general 000029 | fermionic channel a newly discovered mathematical operation.
