You can’t divide the indivisible, unless you use quantum mechanics. Physicists have now turned to quantum effects to split phonons, the smallest bits of sound, researchers report in the June 9 Science ...

Sound is usually treated as the most familiar of physical phenomena, the background noise of daily life rather than a frontier of fundamental physics. Yet in laboratories around the world, carefully ...

Entanglement—linking distant particles or groups of particles so that one cannot be described without the other—is at the core of the quantum revolution changing the face of modern technology. While ...

Schrödinger dynamics inspired novel wave physics explorations, including symmetry design, Floquet topology, adiabatic pumping, non-Hermitian dynamics, non-Abelian physics and nonlinear phenomena. In a ...

A crucial building block for quantum computers based on sound has been shown to work for the first time. One popular way of building quantum computers is to encode information into quantum states of ...

Researchers have proposed a new way of using quantum light to 'see' quantum sound. A new paper reveals the quantum-mechanical interplay between vibrations and particles of light, known as photons, in ...

Quantum entanglement has shifted from a philosophical puzzle to a design brief for engineers working at the scale of atoms, photons and phonons. As researchers learn to control this fragile ...

Andrew N. Cleland receives funding from various US federal funding agencies. He is a fellow of the American Physical Society (APS) and the American Association for the Advancement of Science. He is ...
