In leap for quantum computing, silicon quantum bits establish a long-distance relationship
In an important step forward in the quest to build a quantum computer using silicon-based hardware, researchers at Princeton have succeeded in making possible the exchange of information between two qubits located relatively far apart -- about the length of a grain of rice, which is a considerable distance on a computer chip. Connecting two silicon qubits across this distance makes possible new and more complex silicon-based quantum computer circuits. The study was published in Nature. (2019-12-25)
