Pojen Chuang et al. of National Cheng Kung University in Tainan, Taiwan and his co-workers used two quantum point contacts as spin injectors and detectors to achieve complete control of the electron spins (spin injection, manipulation and detection) in a purely electrical all-semiconductor spin field-effect transistor which is compatible with large-scale integration and promising for future spintronics based information processing. Read the original article: Pojen Chuang, Sheng-Chin Ho, L. W. [...]
Kolkowitz et al. of Harvard University used nitrogen-vacancy centers in diamond to make single-spin qubits for measuring Johnson noise thermally induced in a conductive silver film in the vicinity indicating that nanoscale quantum systems may be controlled by nearby electrodes. Read the original article: Thermally induced electrical currents, known as Johnson noise, cause fluctuating electric and magnetic fields in proximity to a conductor. These fluctuations are intrinsically related to the conductivity [...]
