Quantum entanglement is when two quantum particles that are separated by a great distance become an entangled system and share a quantum state. Plainly stated, when one of these particles is touched, its entangled pair can feel it. PhD student Giovanni Milione said that “At the heart of quantum entanglement is ‘nonseparability’ – two entangled things are described by an unfactorizable equation. Interestingly, a conventional laser beam (a laser pointer)’s shape and polarization can also be nonseparable.”Physicists from The City College of New York (CCNY) have found that beams from typical laser pointers are able to mimic quantum entanglement.Laser pointer cutting machine technology uses the laser beam to the surface of the metal sheet when the release of energy. The metal sheet is melted and the slag is blown away by the gas. Since the blue laser pointer power is very concentrated, only a small amount of heat is transferred to other parts of the sheet metal, resulting in a small or no deformation. The use of laser can be very accurate cutting complex shape of the blank, the cutting of the blank no longer need for further processing.
