Mathematical classical mechanics is underpinned by Hamiltonian flows on symplectic and more general Poisson manifolds, with conserved energy functions defining vector fields whose integrability is ...

Researchers from the Okinawa Institute of Science and Technology (OIST) say they've taken a step towards "Schrödinger’s cat ...

When you throw a ball in the air, the equations of classical physics will tell you exactly what path the ball will take as it falls, and when and where it will land. But if you were to squeeze that ...

Quantum field theory (QFT) is the basis of the Standard Model of particle physics. This video explains what QFT is, why it’s ...

Simulations deliver hints on how the multiverse produced according to the many-worlds interpretation of quantum mechanics might be compatible with our stable, classical Universe. Figure 1: Like a set ...

Two people measure the time it takes for a pendulum to complete one full swing separately. They check how their clocks are running, agree on what counts as one full swing from start to finish, and ...

Quantum circuits are systems consisting of logic gates that operate on quantum bits (qubits) to process information and perform calculations based on principles of quantum mechanics. Quantum circuits ...

Physicists at Tampere University, Harvard, and TU Dresden have shown that even maximally chaotic quantum systems retain a ...

While AI has been getting most of the attention as a world-changing technology lately, there’s another technology on the horizon that has the potential to reshape the world: quantum computing.

Two decades ago, scientists seemed on the verge of understanding biology in a new, quantum way. Life unfolds over an incomprehensible span of scales, from our planet-enveloping biosphere at one end, ...
