Demonstration of a Two-Bit Controlled-NOT Quantum-Like Gate using Classical Acoustic Qubit-Analogues

Case ID:

This technology is an implementation of a logic gate using acoustic waves. It is a two-bit controlled NOT gate that allows acoustic waves to be used to perform logic operations like those that can be performed in traditional quantum computers.

Controlled NOT (CNOT) gates are quantum logic gates that are fundamental components of quantum computers. For example, it can be used to create entangled states and similarly disentangled states. Traditional quantum computing often requires expensive equipment that suffer from scalability challenges. However, other, newer types of quantum computing, such as the use of photons (particles of light) or phonons (pseudo-particles of sound) show promise for building reliable, scalable quantum computers.

This technology builds an important component for a quantum-like computer based on acoustic analogues to traditional quantum computing problems. Furthermore, it helps solve the problem of scalability and the tendency for quantum information to rapidly deteriorate in actual quantum computing devices.
