Scientists have developed a proficiency to change the color and embodiment of photons . This could be a boon for quantum calculation .
photon are the term used to name the packet of energy that fell through the vacuum of space at the speed of light . Although they are discrete packet of vitality , they each have a characteristic wavelength associated with them . That wavelength in visible light determines the color , or energy level , of the photon . Although we ca n’t see other photons , they too have certain wavelength associated with their push levels .
Photons are basic enough that they do n’t degrade . They do n’t change unless act upon . mostly , the only room to “ act upon ” it is to get it be absorbed by some substance . That makes a photon into an on - off shift , which is useful , but not as versatile as a dimmer . scientist have found a way to change the wavelength of photon without absorbing them .
They made a crystal into which two streams of photons were channeled . One was a load of infrared photons of 1300 micromillimetre wavelengths . The other was a laser beam of 1550 nm photons . The crystallization latticework meld and directed the two flow , give off a flow of 710 nanometre wavelength photons .
With crystals like this , and some careful calculations , the “ on - off ” nature of computing might be changed . alternatively of switching bits on or off , they can be in many different country . Instead of each bite being a part of one calculation , it can be a part of many at the same fourth dimension . Ideally , all the thing a estimator now does consecutive , could instead be done mostly at the same time .
