Physics textbooks will now have to be revised thanks to the work of researchers who, while at the Centre for Quantum Technologies (CQT) at NUS, proved that two basic quantum mechanics theories are not distinct, but rather, different ways of observing the same phenomenon. Their findings were published in mid-December 2014 in Nature Communications.

CQT Principal Investigator Associate Professor Stephanie Wehner, CQT PhD student Jedrzej Kaniewski and Dr Patrick Coles discovered that wave-particle duality is actually the quantum uncertainty principle in disguise. Read more about this breakthrough.
