What is it about?
Here, we demonstrate how to manipulate coupled granules with external drivers to achieve controlled accumulation of the Berry phase in a two-level elastic bit, which is a classical counterpart to qubits. The paper shows how to manipulate elastic bit states and realize quantum-analog logic gates using the Bloch sphere representation. The computation of the Berry phase for different system states, which provides information about the topological nature of the system, is a significant accomplishment.

Why is it important?
It is important for the understanding the scalability of the elastic bit, as the traditional quantum bit can collapse the wave function and need supercool temperatures. The elastic bit can withstand these problems and create a sustainable data transmission system.
Perspectives
Innovative advances in materials science, particularly in the creation of materials with unique mechanical properties, may result from the understanding of the topological properties of elastic bits through Berry phase calculations. It may be possible to further understand the complexities of higher-dimensional topological spaces by applying these ideas to systems with more than two levels, such as elastic trits that are comparable to qutrits.
