Scientists Find a Clever Way to Read Quantum Information Without Destroying It
Simulations suggest that one type of qubit could reveal its state through its own electric current, helping researchers monitor quantum computers with less disturbance and fewer components. Like a bit in an ordinary computer, a qubit stores information using states labeled 0 and 1. A qubit can also be prepared in a superposition, a quantum [...]
