A variation on the theory of quantum gravity — the unification of quantum mechanics and Einstein's general relativity — could help solve one of the biggest puzzles in cosmology, new research suggests.

They ask us to believe, for example, that the world we experience is fundamentally divided from the subatomic realm it’s built from. Or that there is a wild proliferation of parallel universes, or ...

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Are the mysteries of quantum mechanics finally starting to crack, or are we just getting better at asking sharper questions? Since the 2022 Nobel Prize in Physics honored experiments on quantum ...

Albert Einstein’s theory of gravity, general relativity, is famously incomplete. As proven by physics Nobel laureate Roger Penrose, when matter collapses under its own gravitational pull, the result ...

Time may feel smooth and continuous, but at the quantum level it behaves very differently. Physicists have now found a way to measure how long ultrafast quantum events actually last, without relying ...

Google’s latest Doodle celebrates World Quantum Day. Quantum computers are one of Google’s big research projects, but the fundamentals can be hard to communicate. For today’s Doodle, Google uses a ...

Scientists have demonstrated a new method for measuring how long ultrashort events like quantum tunneling to occur at quantum scale time.

Did you know that China has invested over $15 billion in quantum computing research? This staggering figure highlights the intense global competition to lead in this groundbreaking technology. Quantum ...

Four decades ago, physicists were theorizing that the mind-bending mechanics of quantum physics could be harnessed to make a new kind of computer that’s exponentially more powerful than conventional ...

What if the impossible became routine? Imagine solving a problem so complex it would take a classical computer 20 million years to crack, now imagine doing it in just 15 minutes. That’s exactly what ...
