Quantum phenomena can often be explored in a more accessible way by so called quantum analogues, making its understanding and applications more achievable. The authors experimentally realise acoustic Bell states by superposition of coupled 1D elastic waveguides, which allows them to explore a section of the Bell’s state Hilbert space by tuning the complex amplitude coefficients, opening options to exploring quantum entanglement with a classical equivalent from phononics.
