New method for detecting quantum states of electrons

Researchers have devised a new method -- called image charge detection -- to detect electrons' transitions to quantum states. Electrons can serve as quantum bits, the smallest unit of quantum information; these bits are foundational to larger computational systems. Quantum computers may be used to understand the mechanism of superconductivity, cryptography, artificial intelligence, among other applications.
