The main drawback of the encoding is that the logical states themselves are challenging to produce. Here we present a method for generating optical GKP-encoded qubits by coupling an atomic ensemble to a squeezed state of light. Particular outcomes of a subsequent spin measurement of the ensemble herald successful generatio","authors_text":"Alexei Gilchrist, Ben Q. Baragiola, Keith R. Motes, Nicolas C.
