Quantum entanglement can be described as a physical phenomenon which happens when groups or particles are created in a process such that the quantum state of each particle cannot be independently verified and instead a instead, a quantum state may be given for the system as a whole.
A microwave laser which has been built using tiny particles which act as semiconductors and could find use in exploring strange phenomena such as quantum entanglement.
Quantum dots are tiny particles of light-emitting nanocrystals which can absorb light from one wavelength and convert it to saturated light of a specific wavelength. This is used to build masers which emit light at longer wavelengths –more than the traditional lasers. The device could also lead to advances in quantum computing. Quantum dots could radically improve the look of LCD screens on TVs, smartphones and tablets and no wonder most companies like Apple, Samsung and Amazon are experimenting with quantum dots in their devices
