Quantum robotics

[17] The topic of free-space quantum communication between mobile platforms, which was initially implemented to fulfill the need for free-space QKD and entanglement distribution using mobile nodes, was brought into robotics domain as an emerging interdisciplinary mechatronics topic to investigate and explore the interface between the quantum technologies and robotic systems domain.

Although as a newfound emerging area, other benefits are anticipated in the future research by accessing the fast-growing and forthcoming quantum advantages.

[1][2][3][4][5][7] The paper contributes to providing the complementary background needed for the research in integrating free-space quantum communication into the robotics field.

The schematic representation of the experimental setup for achieving quantum entanglement through the spontaneous parametric down-conversion process is shown in the figure.
