Ruth:I looked at the brief summary but not yet at the journal article. However it sounds as though they created a superposition of two quantum states of the EM field, where the two states were of different number of quanta (photons). So for example (using smaller numbers), you can think of one state as a state of 10 quanta and the other as a state of 20, which looks like
