Experimental method measures robustness of quantum coherence

Researchers at the UAB have come up with a method to measure the strength of the superposition coherence in any given quantum state. The method, published in the journal Proceedings of the Royal Society A, is based on the ...

Quantum 'paparazzi' film photons in the act of pairing up

In the quantum world of light, being distinguishable means staying lonely. Only those photons that are indistinguishable can wind up in a pair, through what is called Hong-Ou-Mandel interference. This subtle quantum effect ...

Diagnosing diseases in real time with smartphones

Smartphones are capable of giving us directions when we're lost, sending photos and videos to our friends in mere seconds, and even helping us find the best burger joint in a three-mile radius. But University of Houston researchers ...

Quantum reality more complex than previously thought

Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you open them, it turns ...
