    Behind IBM’s Quantum Computing Solution

    Quantum computing performs new operations on data or operations outside standard models of computation. We look at IBM's quantum computing technology.

    IBM scientists have achieved a further advance by combining 5 qubits in the lattice architecture, which demonstrates a key operation known as a parity measurement—the basis of many quantum error-correction protocols.

    Here is an image of Grover's search algorithm (a quantum database search algorithm) in the composer. A universal quantum computer can be programmed to perform any computing task and will be exponentially faster than classical computers for a number of important applications for science and business.

    Working with colleagues at IBM's T.J. Watson Lab in New York, the company' scientists in Zurich are building their own quantum research lab. Here, IBM scientist Andreas Fuhrer takes a closer look at the cryogenic refrigerator that also will help keep qubits at temperatures colder than the deepest parts of outer space.
 

IBM Research is making quantum computing available to members of the public who can access and run experiments on the company's quantum processor. This endeavor has been about 35 years in the making, with perhaps another decade or more to go before IBM can deliver a universal quantum computer. According to IBM, quantum computing uses quantum physics, also called quantum mechanics, to perform new operations on data or operations outside the standard models of computation. “The power of the quantum computer is that it is based on a logic that is not limited merely to on-or-off, true-or-false scenarios,” reads a description of the technology on the IBM Research quantum computing site. “Quantum computing has bits, just like any computer. But instead of ones and zeros, quantum bits (or qubits) can represent a one, a zero or both at once—a phenomenon known as superposition. The superposition that occurs in a quantum system is so different from that which occurs in classical systems that it can allow two of these qubits to behave in ways that cannot be explained by the individual components.” This eWEEK slide show examines key features of IBM's quantum computing technology.
