There is a glaring gap in our knowledge of the physical world: none of our well-established theories describe gravity’s quantum nature. Yet physicists expect that this quantum nature is essential for ...

This device is known as a Josephson junction. It’s the foundational building block of quantum computers and advances of it ...

Does the universe notice that we're paying attention to a quantum experiment? The answer goes against everything we thought we knew.

"Dark photon" theory says light's interference patterns may emerge from quantum particles, not waves, upending centuries of ...

As strange and unique as the laws of the quantum realm appear in our everyday experience, every now and then experiments catch sight of phenomena that seem both alien and yet eerily familiar. For the ...

In the past year, two separate experiments in two different materials captured the same confounding scenario: the coexistence ...

As physicists search for a theory of quantum gravity, new results show that classical gravity can still interact with quantum fields to allow matter to become entangled. When you purchase through ...

Quantum spin liquids are exotic states of matter in which spins (i.e., the intrinsic angular momentum of electrons) do not ...

A stable "exceptional fermionic superfluid," a new quantum phase that intrinsically hosts singularities known as exceptional ...

Learning how a physical system behaves usually means repeating measurements and using statistics to uncover patterns. That ...

A thought experiment that was at the heart of an argument between famed physicists Albert Einstein and Niels Bohr in 1927 has finally been made real. Its findings elucidate one of the core mysteries ...

A real mind-melter: Quantum mechanics is strange, but even for a field of science that regularly defies our conventional understanding of reality, the latest discovery is particularly baffling.
