Innovation in technology seems to be the phrase of the decade. Scientists invent and improve equipment for a better and easier usage. The perfect example lies in Princeton University’s new invention. Because of their genius ideas, now the smallest laser in the world is the size of a grain of rice.
Of course, the smallest laser can only be built with the smallest objects. That is why the laser uses the smallest particles that exist, meaning atoms. These scientists did not use regular atoms, but artificial ones. Their popular name is quantum dots.
This new outstanding innovation uses quantum dots as a more effective power source. Electrons travel thorough these artificial atoms using less electricity that an iron uses. To be more specific, the laser uses the billionth part of electrical power that the iron uses. Even though it uses such little energy, it is diffused in the microwave sphere.
The new laser is said to be an exquisite example of electron movement and the interaction between them and light. This invention can be used in quantum computing fields because there are not many devices available to use. The laser could be a unique and refreshing device that could revolutionize quantum computing.
The scientist team’s main goal is to create a computing system using just semiconductor material. Such material is usually consisted of quantum dots. Their initial purpose was to develop a research in quantum pairs because no one has ever experienced on something similar. These pairs consist the segment for quantum computers.
At the University of Maryland-National Institute of Standards and Technology, a subordinate associate professor at the Joint Quantum Institute affirmed that the recent research is a revelation to their life-time purpose of the “entanglement between quantum bits in semiconductor-based gadgets”.
Jason Petta, Princeton’s leading professor in the study explained in a few words their research. In order to emit photons, the team had to compose dots so that those quantum dots could sustain those photons. While electrons jumped from high to low energy ranks between two dots, then the photons should be released.
To clarify this statement he compared the photons and electrons with people. When people are trying to cross over a wide river they usually jump onto different surface rocks. In this case, the rocks are extremely little, so they can only hold one person at a time.
In other words, researchers need to create a controllable environment for the electrons in quantum computing.
