Now, two unrelated-but-similar experiments confirm that, in a double-slit experiment, detection of a photon’s path (its ...

Take, for instance, quantum entanglement, which says that the state of one particle can be determined by examining the state ...

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to ...

Quantum mechanics is weird. When you think you have reached the bottom of its weirdness, you always discover a new ...

During a series of experiments in the mid-80s, the three scientists demonstrated quantum mechanics on a circuit big enough to be held in one’s hand. Three scientists from the UK, France and the US ...

Scientists in China have performed an experiment first proposed by Albert Einstein almost a century ago when he sought to ...

Out of order: quantum mechanics defies causal order. (Courtesy: Shutterstock/Sam72) An experiment has confirmed that quantum mechanics allows events to occur with no definite causal order. The work ...

Thomas Young, born 250 years ago this week, was a polymath who made seminal contributions in fields from physics to Egyptology. But perhaps his most enduring legacy is proving Isaac Newton wrong about ...

Quantum mechanics: a branch of physics that is, to many, confusing and misunderstood. It encompasses and deals with the actions and interactions between energy and both subatomic particles and atoms.
