A century-old thought experiment on wave–particle duality is brought into the laboratory using a single trapped atom ...

In the late 1970s, legendary physicist John Wheeler proposed a radical question: Exactly when does the universe notice that we're paying attention to a quantum experiment? And does it really matter?

Two landmark quantum experiments have sharpened one of the oldest arguments in modern physics, and the verdict is not kind to Albert Einstein’s instincts about reality. By stripping classic thought ...

An experiment outlined by a UCL-led team could test whether relatively large masses have a quantum nature, resolving the question of whether quantum mechanical description works at a much larger scale ...

Infleqtion, a global leader in quantum sensing and quantum computing, announced research results from a collaboration with the University of Wisconsin–Madison that demonstrate a more reliable way to ...

Physicists have found a way to measure how long ultra-fast quantum events actually take—without using a clock at all.

The impact of these experiments builds the foundations necessary for the application of quantum computation at scale which will remain relevant along the path to the fault-tolerance era.

Quantum computing is nearing the point of practical use, but scientists still need to make some specific breakthroughs.

A new experiment could in principle test the quantumness of an object regardless of its mass or energy. An experiment outlined by a UCL (University College London)-led team of scientists from the UK ...
