Some Bipartite States do not Arise from Channels
Mary Beth Ruskai
It is well-known that the action of a quantum channel on a state can be represented, using an auxiliary space, as the partial trace of an associated bipartite state. Recently, it w…

Permutationally Invariant Codes for Quantum Error Correction
Harriet Pollatsek, Mary Beth Ruskai
A permutationally invariant n-bit code for quantum error correction can be realized as a subspace stabilized by the non-Abelian group S_n. The code corresponds to bases for the tri…
