Innsbruck Researchers: Fault-Tolerant Method on Ion Trap Quantum Computer Translates to Other Quantum Computing Architectures

…For quantum computers to be useful in practice, errors must be detected and corrected…

…Quantum computers are inherently much more susceptible to disturbances and will thus probably always require error correction mechanisms, because otherwise errors will propagate uncontrolled in the system and information will be lost…

…In Innsbruck, Austria, a team of experimental physicists has now implemented a universal set of computational operations on fault-tolerant quantum bits for the first time, demonstrating how an algorithm can be programmed on a quantum computer so that errors do not spoil the result…
