可控非(CNOT)门是开启量子计算能力的关键,因为它是通用门的基本组成部分。我们演示了使用经典量子比特声学类似物(这里称为逻辑phi-bits)的两位C-NOT类量子门的操作。逻辑phibit由由三个弹性耦合波导平行阵列组成的外部驱动非线性声学超材料支撑。逻辑菲比特具有与三个波导中声波的两个独立相对相位相关的两态自由度。一个简单的物理操作涉及一个外部驱动器的频率失谐被证明是操作在逻辑的斐位对的希尔伯特空间的复向量。该操作实现了具有明确可测量输入和输出的系统和可预测的C-NOT门。将这种方法扩展到更多的phi位的可能性是有希望的。
The Controlled-NOT (CNOT) gate is the key to unlock the power of quantum computing as it is a fundamental component of a universal set of gates. We demonstrate the operation of a two-bit C-NOT quantum-like gate using classical qubit acoustic analogues, called herein logical phi-bits. The logical phi-bits are supported by an externally driven nonlinear acoustic metamaterial composed of a parallel array of three elastically coupled waveguides. A logical phi-bit has a two-state degree of freedom associated with the two independent relative phases of the acoustic wave in the three waveguides. A simple physical manipulation involving the detuning of the frequency of one of the external drivers is shown to operate on the complex vectors in the Hilbert space of pairs of logical phi-bits. This operation achieves a systematic and predictable C-NOT gate with unambiguously measurable input and output. The possibility of scaling the approach to more phi-bits is promising.
