Darmstadt physicists have developed a technique that could overcome one of the biggest hurdles in building a practically-relevant quantum computer. They make use of an optical effect here discovered by British photo pioneer William Talbot in 1836. The team led by Malte Schlosser and Gerhard Birkl from the Institute of Applied Physics at Technische Universität Darmstadt presents this success in the journal Physical Review Letters.
