我们提出了一种外部驱动的声学超材料模型，该模型由耦合声波导的非线性并行阵列组成，支持逻辑phibit，量子比特的经典类似物（qubit）。相关的多菲比特系统的描述强调了在其相应的希尔伯特空间中表示的菲比特和多菲比特向量状态的重要性。实验数据验证了单菲比特哈达玛门和相移门的实现。一个三菲比特系统也被用来说明多菲比特门的发展，以及一个简单的量子算法。这些演示为基于声学超材料的数字量子模拟计算平台的实现奠定了基础，该平台可以实现量子样门，并可能提供一个有效的材料模拟平台。
We present a model of an externally driven acoustic metamaterial constituted of a nonlinear parallel array of coupled acoustic waveguides that supports logical phi-bits, classical analogues of quantum bits (qubit). Descriptions of correlated multiple phi-bit systems emphasize the importance of representations of phi-bit and multiple phi-bit vector states within the context of their corresponding Hilbert space. Experimental data are used to demonstrate the realization of the single phi-bit Hadamard gate and the phase shift gate. A three phi-bit system is also used to illustrate the development of multiple phi-bit gates as well as a simple quantum-like algorithm. These demonstrations set the stage for the implementation of a digital quantum analogue computing platform based on acoustic metamaterial that can implement quantum-like gates and may offer promise as an efficient platform for the simulation of materials.
