New level of Quantum computation

Article first published as Reaching New Horizons in Quantum Computation on Technorati.

IBM researchers have developed ways to overcome certain errors in quantum computation.
IBM researchers worked on the superconducting 3D qubits utilizing microfabrication techniques. Qubits are the basic units of information in quantum computing. They also worked on the 2D qubits to develop a “Controlled NOT gate” or CNOT gate, which is building block of quantum computation.

“The superconducting qubit research led by the IBM team has been progressing in a very focused way on the road to a reliable, scalable quantum computer. The device performance that they have now reported brings them nearly to the tipping point; we can now see the building blocks that will be used to prove that error correction can be effective, and that reliable logical qubits can be realized,” observes David DiVincenzo, professor at the Institute of Quantum Information, Aachen University and Forschungszentrum Juelich.

Researchers are considering this as a major leap in quantum computing.
“In the past, people have said, maybe it’s 50 years away, it’s a dream, maybe it’ll happen sometime,” said Mark B. Ketchen, manager of the physics of information group at I.B.M.’s Thomas J. Watson Research Center in Yorktown Heights, N.Y. “I used to think it was 50. Now I’m thinking like it’s 15 or a little more. It’s within reach. It’s within our lifetime. It’s going to happen.”
IBM researchers will present this research at the annual meeting of American Physical Society taking place from February 27 – March 2, 2012 in Boston, Mass. Researchers will present that how close they are in solving the problems in quantum computation both by elevating the lifetime of the qubits of information and by improving the pace of computation.
