The researchers increased the coherence time of their new type of qubit to an impressive 0.1 milliseconds, which is almost a thousand times faster than the previous record."Unlike traditional electron-charged qubits, our qubits can perform 10,000 operations with high accuracy and speed," said Dafei Jing, a co-appointed professor at the University of Notre Dame's Argonne Nanomaterials Center.The team's qubits encode quantum information in the moving (charge) states of the electron, which is why they are called charge qubits. These qubits are particularly attractive because of their ease of production and operation, as well as compatibility with existing infrastructures for classical computers.A team qubit is a single electron trapped on the ultrapure surface of solid neon in a vacuum. Neon is important because it is resistant to environmental influences.After additional optimization, the team not only improved the surface quality of the neon, but also significantly reduced interference. The researchers ' work was published in Nature Physics.Another important aspect is the scalability of the qubit to communicate with many other qubits. The team showed that two qubits on an electron can connect to the same superconducting circuit, allowing information to be transferred between them.The team will continue to work on optimizing its electronic qubit, aiming to increase the coherence time and interaction of two or more qubits.The study involved researchers from various academic and research institutions, including the Lawrence Berkeley Lab, the Massachusetts Institute of Technology, the University of Chicago, and the University of Notre Dame.<a href="https://carder.market/login/" target="_blank">https://carder.market/login/</a></blockquote>
