Researchers in Japan Find Way to Precisely Control Qubits Without Previous Limitations

…To get to the point where quantum computers can meet their expected performance potential, the development of large-scale quantum processors and quantum memories is needed… Precise control of qubits—or quantum bits, the basic building blocks of quantum computers—is critical to do this…

…[R]esearchers from Yokohama National University in Japan have found a way to precisely control qubits without the previous limitations…

…[R]earchers were able to demonstrate control of qubits by manipulating the electron spin through a combination of microwave manipulation and local optical shifting of transition frequencies of atoms and molecules, a process known as the Stark Shift…
