Researchers at IBM have demonstrated for the first time the ability to detect and measure the two types of quantum errors (bit-flip and phase-flip) that will occur in any real quantum computer. The researchers have also shown a new, square quantum bit circuit design that could scale to larger dimensions.
“Quantum computing could be potentially transformative, enabling us to solve problems that are impossible or impractical to solve today," said Arvind Krishna, senior vice president and director of IBM Research. “While quantum computers have traditionally been explored for cryptography, one area we find very compelling is the potential for practical quantum systems to solve problems in physics and quantum chemistry that are unsolvable today. This could have enormous potential in materials or drug design, opening up a new realm of applications.”
The research is published in the April 29 issue of the journal Nature Communications (DOI: 10.1038/ncomms7979).
