A certain amount of noise is inherent in any quantum system. For instance, when researchers want to read information from a quantum computer, which harnesses quantum mechanical phenomena to solve certain problems too complex for classical computers, the same quantum mechanics also imparts a minimum level of unavoidable error that limits the accuracy of the measurements. Scientists can effectively get around this limitation by using “parametric” amplification to “squeeze” the noise –– a quantum phenomenon that decreases the noise affecting one variable while increasing the noise that affects its conjugate…
