EXCERPTS: . . . But if aliens exist, how do they communicate? A new study by the Imperial College London quantum physicist Terry Rudolph suggests that aliens could be using stars to communicate with each other secretly. [...] They harness the power of entangled photons from various stars to send these hidden messages.
This idea of communication appears to be random blinking to others. [...] Quantum entanglement has been demonstrated experimentally with photons in communication. It just requires the receivers to use only linear optics (passive interferometers) and photon number counting and to be able to communicate classically.
[...] In his paper, Rudolph stated that “The speculation in the title arises from the further observation that the natural way for a circumspect civilization to hide their photonic entanglement distribution is to use the thermal light already being emitted from the various stars they visit.”
For such communication, they must know the number of photons in the modes they have chosen to use. This would necessitate performing a quantum non-demolition measurement of the photon number.
Rudolf wrote, “Because the thermal light they are measuring is diagonal in the number basis, even this process can be rendered in principle indiscernible to those of us excluded from the conversation.” (MORE - details)
