Quantum computers need special materials called topological superconductors—but they’ve been notoriously difficult to create.

(a) Schematic of non-local mode selection by metasurface-integrated quantum analog operation. F^1, F^2, F^3, and F^4 are the differential operators. The green area has been designed to construct ...

A pair of photons enters an optical maze, and sometimes they leave as something new. Not new in the everyday sense, since both were still photons when they came out.

Noncommutative quantum mechanics extends the conventional framework of quantum theory by postulating that spatial coordinates and momenta do not commute. This departure from classical concepts ...

Researchers used a non-Hermitian version of the Hubbard model with spin-resolved asymmetric hopping to reveal how spin depairing creates a stable superfluid with embedded exceptional points. A stable ...

Quantum teleportation has quietly crossed a threshold that once belonged to science fiction, moving from pristine lab setups into the messy reality of live internet infrastructure. Instead of ...
