Researchers have designed a new device that can efficiently create multiple frequency-entangled photons, a feat that cannot be achieved with today's optical devices. The new approach could open a path ...

Quantum mechanics and relativity are the two pillars of modern physics. However, for over a century, their treatment of space ...

Einstein’s claim that the speed of light is constant has survived more than a century of scrutiny—but scientists are still ...

How likely you think something is to happen depends on what you already believe about the circumstances. That is the simple concept behind Bayes’ rule, an approach to calculating probabilities, first ...

Dr. Pravir Malik is the founder and technologist of QIQuantum and the Forbes Technology Council group leader for Quantum Computing. For decades, the promise of quantum computing has rested on the ...

What if the flow of time isn’t as one-way as it seems? Researchers from the University of Surrey have uncovered evidence that in the strange world of quantum physics, time could theoretically run both ...

A new physics paper takes a step toward creating a long-sought "theory of everything" by uniting gravity with the quantum world. However, the new theory remains far from being proven observationally.

A rift runs deep through the heart of physics. The general theory of relativity, which describes gravity, clashes with quantum physics. In an effort to seal that physics fissure, untold numbers of ...

Quantum physics fundamentally redefines our understanding of nature by describing the behaviour of matter and energy at the smallest scales. Unlike classical theories, quantum mechanics reveals that ...

Researchers at the University of Oxford say they’ve achieved quantum teleportation — stitching together separate quantum computers to run an algorithm collaboratively, across a distance, in a ...

Physicist Paul Davies’s Quantum 2.0: The past, present and future of quantum physics ends on a beautiful note. “To be aware of the quantum world is to glimpse something of the majesty and elegance of ...
