Quantum communication: Optical communication with invisible photons

Suhail Zubairy (Texas A&M University)

It has long been assumed in physics that for information to travel between two parties in empty 
 space, ¡®¡®Alice¡¯¡¯ and ¡®¡®Bob,¡¯¡¯ physical particles have to travel between them. Here, using the
 ¡®¡®chained¡¯¡¯ quantum Zeno effect, we show how information can be transferred between Alice
 and Bob without any physical particles traveling between them.
