Identification of decoherence-free subspaces without quantum process tomography
Identification of decoherence-free subspaces without quantum process tomography
Characterizing a quantum process is the critical first step towards applying such a process in a quantum information protocol. Full process characterization is known to be extremely resource-intensive, motivating the search for more efficient ways to extract salient information about the process. An example is the identification of ``decoherence-free subspaces,'' …
