ABSTRACT

We present the theory and construction of a new class of designs, which we call SEEDs (spontaneous emission error designs), arising in the study of decay processes of certain quantum systems used in the newly emerging field of quantum computing. We show that there is a simple and surprising connection between subspaces of the system Hilbert space, stable against these quantum jumps and the incidence matrices of SEEDs.
