Experimental demonstration of pseudospin behavior and classical entanglement in a phononic structure (Conference Presentation)

We present experimental and theoretical demonstrations of quantum-like behavior in phononic structures. This demonstration extends the notion of classical “entanglement” or classical “nonseparability” to the emerging field of phononics, opens the door for acoustic analogues to true quantum system in quantum information processing, since the preparation and control of entangled superposition of states is an essential ingredient for harnessing the second quantum revolution.
