    IBM scientists: two breakthrough in quantum computer research

     [ Abstract ]IBM company scientists the latest research results for the first time that can simultaneously detect and measure the two types of quantum error, and proved a new square quantum bit ring design.

    IBM Hope that through the development of new drugs and materials of quantum computer

    If a quantum computer can be formed into 50 qubits, add up all the top 500 supercomputers in the world, features are unable to overcome it. IBM company science Published in the "natural communication" magazine two breakthrough, for the first time that can simultaneously detect and measure the two types of quantum error, and proved a new

    quantum bit design is the only square ring can be extended in the larger dimension of the physical structure.

    One of the great challenges facing scientists tried to control the quantum computer, quantum decoherence is to control or remove - error due to heat, caused by electromagnetic radiation or material defects. Two types of quantum widely exist in quantum machine errors in - bit flip and phase reversal will happen in any real quantum computer. But until the papers published before, the scientific community has only solve possibility of a type of quantum

    error. However, to solve the quantum two types of errors, it is a key step towards quantum error correction, the key is to establish a large demand for quantum computer practical and reliable.

    Complex qubit circuit IBM innovation is composed of 4

    superconducting qubits, about 1/4 square inches of chip. "Before this, the work in this field using a linear arrangement, providing a quantum system can only look at the flip errors of incomplete information state, and this does not constitute a practical computer system." IBM's quantum computing team leader Jay Ganbata said, "our 4 bit square chip, can lead us to simultaneously detect two types of quantum error, and can be extended to larger quantum systems."

    IBM, senior vice president and director of research Arvind Krishna said: "although there has been on a quantum computer encryption system has been extensively studied, but we think there is the practical value of the quantum system, it can not solve the problem today to learn physics and chemistry, may have potential in material science, drug design so, to develop a series of new applications. For example, it will allow scientists to get rid of expensive laboratory tests, to speed up the design of materials and new drug ingredients, to accelerate the speed of innovation and other pharmaceutical compounds."

    In addition, quantum computer can also more rapid processing of large databases, can handle diverse, large-scale unstructured data, it will change the way people make decisions, and help researchers across the industry to make new achievements.
