Over 85 years after it began, the Einstein-Bohr debate remains the most consequential intellectual rivalry in modern science ...

Physicist Paul Davies looks back at the past century of quantum mechanics—the most disruptive theory in the history of modern science.

Shaped by a different biology or culture, other intelligent civilisations – if they’re out there – might understand the ...

Rydberg atoms are atoms with one or more outer electrons excited to very high energy levels, which interact very strongly with each other. These atoms are widely used to run quantum simulations and ...

In classical physics, memory is defined in a straightforward way. If a system’s future behavior depends only on its current condition, it is considered memoryless. If earlier states continue to ...

A newly derived “q-desic” equation suggests that quantum effects may subtly alter particle trajectories across the universe.

Researchers at the University of Innsbruck, together with partners from Sydney and Waterloo, have presented a new diagnostic ...

What was your favorite toy growing up? This paradox claims that memory—and every other one—is just a random fluctuation.

Please, please, please don’t make this about time travel ...

Oracle-based quantum algorithms cannot use deep loops because quantum states exist only as mathematical amplitudes in Hilbert space with no physical substrate. Criticall ...

Last year, our most detailed map of the universe yet suggested our understanding of dark energy has been wrong for decades. The shock result is reigniting the search for a better cosmic story ...

Those that solve artificially simplified problems where quantum advantage is meaningless. Those that provide no genuine quantum advantage when all costs are properly accounted for. This critique is ...
