Various quantum analogues have emerged due to recent advances in the design and fabrication of acoustic structures. Acoustic analogous to “entangled” states of quantum bits or qubits offer a transformative new solution to reach some of the goals of quantum information science. Beams of linear acoustic waves support degrees of freedom (DOF), analogous to quantum mechanics and light beams. The states associated with these DOFs—that we named phase-bits or phi-bits—are algebraically non-separable, like the DOF of a single quantum particle. The strong coupling and nonlinearity of acoustic waves in our waveguides offer new ways to realize non-separable states for classical multipartite systems that span exponentially complex Hilbert spaces with much larger dimensions [1,2]. These acoustic structures enable quantum analogue computing even at room temperature and for long periods of coherence.
