Quantum robotics

Field of robotics, physics From Wikipedia, the free encyclopedia

Quantum robotics is an interdisciplinary field that investigates the intersection of robotics and quantum mechanics. This field, in particular, explores the applications of quantum phenomena such as quantum entanglement within the realm of robotics. Examples of its applications include quantum communication in multi-agent cooperative robotic scenarios, the use of quantum algorithms in performing robotics tasks, and the integration of quantum devices (e.g., quantum detectors) in robotic systems.[1][2]

Introduction

The free-space quantum communication between mobile platforms was proposed for reconfigurable quantum key distribution (QKD) applications using unmanned aerial vehicle (UAVs, a.k.a. drones)[3] in 2017. This technology was later advanced in various aspects in mobile drone and vehicle platforms in several configurations such as drone-to-drone, drone-to-moving vehicle, and vehicle-to-vehicle systems.[4][5][6][7][8]

Some research has contributed to low size, weight and power quantum key distribution system for small form UAVs,[9] characterization of a polarization-based receiver for mobile free space optical QKD,[10] and optical-relayed entanglement distribution using drones as mobile nodes.[11] 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.[1] The main advantage of such integrated technology is the guaranteed security in communication between multiagent and cooperative autonomous systems. Other advances are anticipated.[1]

Quantum entanglement

According to quantum mechanics, entanglement occurs when more than one particles become connected. If the state of one particle change then it will instantly change the sate of other particles regardless of their distance. Entangled sensors do the same kind of work and achieve strong sensitivity. A group of quantum robots can measure magnetic fields, gravitational fields and other physical properties using entangled sensors with high rate of accuracy. Again the connection of one robot to other is increased (become strong) by quantum entanglement.

Quantum teleportation

Quantum teleportation is the transfer of quantum information (not physical objects). This is used in case of multi robot process. One robot is programmed with a complex quantum update. Then that robot can teleport that complex quantum information (the update) to other robots. This teleportation or communication is very secure because all the work is done in quantum state.

Kinematics

Quantum computing has been proposed as being optimal for calculating inverse kinematics values.[12][13]

Alice and Bob robots

In the realm of quantum mechanics, the names Alice and Bob are frequently employed to illustrate various phenomena, protocols, and applications. These include their roles in QKD, quantum cryptography, entanglement, and teleportation. The terms "Alice Robot" and "Bob Robot"[1] serve as analogous expressions that merge the concepts of Alice and Bob from quantum mechanics with mechatronic mobile platforms (such as robots, drones, and autonomous vehicles). For example, the Alice Robot functions as a transmitter platform that communicates with the Bob Robot, housing the receiving detectors.
