These challenges have led researchers to explore the possibility of building quantum computers that work using photons\u2014particles of light. Photons can easily carry information from one place to another, and photonic quantum computers can operate at room temperature, so this approach is promising. However, although people have successfully created individual quantum \u201clogic gates\u201d for photons, it\u2019s challenging to construct large numbers of gates and connect them in a reliable fashion to perform complex calculations.<\/p>\n<p>Now, Stanford University researchers have proposed a simpler design for photonic quantum computers using readily available components, according to a paper published Nov. 29 in <i>Optica<\/i>. Their proposed design uses a laser to manipulate a single atom that in turn, can modify the state of the photons via a phenomenon called \u201cquantum teleportation.\u201d The atom can be reset and reused for many quantum gates, eliminating the need to build multiple distinct physical gates, vastly reducing the complexity of building a quantum <a href=\"https:\/\/phys.org\/tags\/computer\/\" rel=\"tag\" class=\"\">computer<\/a>.<\/p>\n<p>\u201cNormally, if you wanted to build this type of quantum computer, you\u2019d have to take potentially thousands of quantum emitters, make them all perfectly indistinguishable, and then integrate them into a giant photonic circuit,\u201d said Ben Bartlett, a Ph.D. candidate in applied physics and lead author of the paper. \u201cWhereas with this design, we only need a handful of relatively simple components, and the size of the machine doesn\u2019t increase with the size of the quantum program you want to run.\u201d<\/p>\n","protected":false},"excerpt":{"rendered":"<p>Today\u2019s quantum computers are complicated to build, difficult to scale up, and require temperatures colder than interstellar space to operate.
