Extending the Life of Quantum Bits


MIT Technology Review

Researchers at the National Institute of Standards and Technology (NIST) have proved, for the first time, that the lifetime of quantum-computing bits can be extended. In their experiment, they showed that by applying specially timed magnetic pulses to qubits, made of beryllium ions, they could prolong the life of the quantum bits from about one millisecond to hundreds of milliseconds. The work is described in this week's Nature.
