According to a team of scientists from Princeton University, it is now quite possible to carry out experiments in quantum computing using a redesigned laser technology known as maser. Maser is made to be the size of a rice grain, but actually stands for Microwave Amplification by Stimulated Emission of Radiation – which means it is an amplifier that works on the same principle as a laser and also emits coherent microwave radiation.

The maser made by the Princeton University team of scientists is composed of quantum dots, that is, tiny bits of semi-conductor material that acts like single atoms but capable of emitting lights at longer wavelengths than normal, conventional lasers.
