(Phys.org)—It was an interesting week in physics as an international team of researchers found that quantum coherence and quantum entanglement are two sides of the same coin—they found a way to show that the two are operationally ...
For decades, scientists have used techniques such as X-ray crystallography and nuclear magnetic resonance (NMR) imaging to gain invaluable insight into the atomic structure of molecules. Such efforts have long been hampered ...
