As the number of transistors on a microprocessor continues to increase at the rate that they are, I predict by the year 2045 will find the circuits on a microprocessor measured on an atomic scale. And, the logical next step will be to create quantum computers, which will harness the power of atoms and molecules to perform memory and processing tasks.
Thanks to the strange laws of quantum mechanics, quantum computers would be able to carry out certain computational tasks much faster than conventional silicon based computers. And, were not just talking about the local processing power of PC’s, Tablets, and Smart Phones it’s much more about the internet then local processing power as the shift to cloud based processing over local becomes the norm.
Not only do optical fibers transmit information every day around the world at the speed of light, but they can also be harnessed for the transport of quantum information. Computer Networks will be able to directly transfer the quantum information stored in an atom onto a particle of light. Such information could then be sent over optical fiber to a distant atom (quantum PC). Among the most promising technologies for the construction of a quantum computer are systems of single atoms, confined in so-called ion traps and manipulated with lasers. In the laboratory, these systems have already been used to test key building blocks of future quantum computers. What makes the construction of these interfaces especially challenging is that the laws of quantum mechanics don’t allow quantum information to be simply copied. Instead, a future quantum internet that is, a network of quantum computers linked by optical channels would have to transfer quantum information onto individual particles of light, known as photons. These photons would then be transported over an optical-fiber link to a distant computing site. Now, for the first time, quantum information has been directly transferred from an atom in an ion trap onto a single photon. The quantum information stored in the photon could thus be conveyed over the optical fiber to a distant quantum computer, where the same technique could be applied in reverse to write it back onto an atom.
Pairing a quantum microprocessor with DNA memory which can achieve a density of 2 petabytes or more per gram of DNA which calculates to allow at least 100 million hours of high-definition video to be stored in about the size of a synthetic DNA teacup. Now you have a recipe that’s more powerful then any super computer cluster in the world today just sitting on your desk! The future of computer technology is bright indeed.
