Scientists have already built basic quantum computers that can perform certain calculations but a practical quantum computer is still years away. In this article, you’ll learn what a quantum computer is and just what it’ll be used for in the next era of computing. You don’t have to go back too far to find the origins of quantum computing..Quantum for researchers. IBM Q is your most passionate collaborator to advance foundational quantum computing research that will make real world impact. Work with the best experts across experimentation, theory, and computer science and explore new possibilities in the field of quantum computing..Any heat in the system can introduce error, which is why quantum computers operate at temperatures close to absolute zero, colder than the vacuum of space. Take a look at how a quantum computer’s dilution refrigerator, made from more than , components, creates such a cold environment for the qubits inside. Look inside a quantum computer.Quantum computer, device that employs properties described by quantum mechanics to enhance computations. As early as the American physicist and Nobel laureate Richard Feynman noted that, as electronic components begin to reach microscopic scales, effects predicted by quantum mechanics.
