Prem Kumar, a professor of mechanics and computer science at Northwestern University, has evolved toward making quantum computing more realistic.Kumar and his colleagues have revealed that they can assemble a quantum logic gate–a basic part of a quantum computer–within an optical fiber.The gate could be a fraction of a track that conveys information securely, more than hundreds of kilometers of fiber, from one quantum computer to another.It could also be used on its own to locate explanations of complex mathematical problems.
A logic gate is a tool that accepts an input, carries out a logic operation on it, and creates an output.The new gate gives a base for researches that reveal the capacities of quantum computers in fiber, says Kumar.
Researchers at IBM, MIT, and many other companies and universities have been working on quantum computers since they were first projected in the 1980s. A quantum computer is a device that processes small pieces of information by utilizing the odd quantum-mechanical properties of constituent parts such as electrons and photons.A quantum computer is supposedly able to work exponentially more information than usual computers can.
