Molecular qubits stick around for longer

Team members Yinqiu Dai and Zhifu Shi with the spectrometer they used in their experiments. Courtesy: X Rong Researchers in China have shown that the spin of a molecular quantum bit (qubit) can remain coherent for more than 1 millisecond – long enough to perform 145 000 basic logic operations. This number, known as the qubit…
