As April 14 marks World Quantum Day, it's clear quantum computing is on a growth path, with the market expected to expand from $1.9 billion in 2024 to $7.5 billion in 2030, a compound annual ...

In quantum physics, the state of a particle is described by a wave equation, which tells us the probabilities of where a particle might be or what its properties might be. This probability wave ...

Apr. 17, 2025 — A study has found a rare form of one-dimensional quantum magnetism in a metallic compound, offering evidence into a phase space that has remained, until now, largely theoretical.

Apr. 15, 2025 — Diamonds with certain optically active defects can be used as highly sensitive sensors or qubits for quantum computers, where the quantum information is stored in the electron ...
