Superconductors are among the most puzzling materials in physics. They conduct electricity with zero resistance, but only under specific conditions that researchers have struggled for decades to ...

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

The new architecture shows how quantum processors could work alongside classical HPC, creating hybrid environments to tackle ...

Repulsive gravity at the quantum scale would have flattened out inhomogeneities in the early universe First light The cosmic microwave background, as imaged by the European Space Agency’s Planck ...

Loop quantum gravity (LQG) is a non-perturbative, background-independent approach to quantising spacetime that seeks to merge the principles of quantum mechanics and general relativity. In this ...

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

Quantum computing in 2026 still isn't a faster laptop. It doesn't make email snappier, and it won't speed up spreadsheets.
