Scientists have demonstrated entanglement and two-particle interference with phonon using an acoustic beam splitter.
The research led by Prof. Andrew Cleland from the Pritzker School of Molecular Engineering at the University of Chicago demonstrated two experiments using an acoustic beamsplitter to split the phonons.Beam splitter with single phonons
In their experiments, the scientists employed phonons with frequencies far beyond the range of human hearing. For the first of the two experiments, the team used the acoustic beam splitter to split a phonon. To preserve the superposition state, the phonon was captured in two qubits. Qubits are the basic units of quantum information analogous to bits in classical computers.
Before measurement, the phonon's presence was spread across both qubits, demonstrating the characteristic of quantum superposition. But, measuring the two-qubit superposition revealed a phenomenon central to quantum computing calledEntanglement refers to a correlation between two or more qubits, such that the state of one qubit depends on the state of the others, even when physically separated, and cannot be described independently.
