Systems and methods for classical entanglement in large multi-qubit acoustic analogue systems

Abstract

Disclosed are systems and methods for scalable, large, multiple logical phi-bit quantum analogue system for achieving controllable classical entanglement (e.g., nonseparability). A method can include driving an array of elastically coupled acoustic waveguides by exciting at least a first acoustic waveguide of the array using a first frequency and a second acoustic waveguide of the array using a second frequency, wherein the first frequency is different from the second frequency. A plurality of acoustic fields propagating through the array of elastically coupled acoustic waveguides can be determined, each respective acoustic field generated based on the driving of the array using the first and second frequencies. A plurality of logical phi-bits can be determined based on spectrally partitioning the one or more acoustic fields, wherein each logical phi-bit of the plurality of logical phi-bits is associated with at least two independently measurable phases.
