Doing more with less: New technique efficiently finds quantum wave functions


Compressive direct measurement allowed researchers to reconstruct a quantum state at 90 percent fidelity (a measure of accuracy) using only a quarter of the measurements required by previous methods.

Duality principle is “safe and sound”: Researchers clear up apparent violation of quantum mechanics’ wave-particle duality

Credit: Institute of Optics / / University of Rochester

When German scientists announced in 2012 an apparent violation of a fundamental law of quantum mechanics, a physicist at the University of Rochester was determined to find an explanation.
