This reminds me of Quantum Cryptography in which Conjugate Coding [1] is used. Conjugate Coding is " A method of transmitting multiple messages in such a way that reading one destroys the others. This is called quantum multiplexing and it uses photons polarized in conjugate bases as "qubits" to pass information."
Even if you can detect such communication it is hard to eavesdrop it because:
"Quantum cryptographic systems take advantage of Heisenberg's uncertainty principle, according to which measuring a quantum system in general disturbs it and yields incomplete information about its state before the measurement. Eavesdropping on a quantum communication channel therefore causes an unavoidable disturbance, alerting the legitimate users." [2]
