The hydrogen atom isn’t just the simplest atom—it’s a perfect playground for exploring quantum mechanics. From Schrödinger’s equation to stunning 3D orbital visualizations, scientists and educators ...

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 ...

MIT researchers have developed a mathematical formulation using classical physics principles to exactly reproduce results from quantum mechanics. By extending the Hamilton-Jacobi equation with density ...

A new study by University of Maryland chemical physicists demonstrates how to control the nuclear spin of molecular hydrogen ...

Theories of quantum mechanics predict that some particles can exist in superpositions, which essentially means that they can be in more than one state at once. When a particle's state is measured, ...

Physicists may have just cracked open a hidden side of the quantum world. For decades, every known particle was thought to belong to one of two categories — bosons or fermions — but researchers have ...

Scientists have created a new way to generate powerful quantum interactions, achieving the first-ever demonstration of ...

In the last episode of my column in Notices of the American Mathematical Society, we looked at a particle moving in an attractive central force whose strength is proportional to the inverse cube of ...

Laser light is injected into an optical cavity to continuously measure the position of a movable mirror. The output light is read out by homodyne detection, and the measurement data are analyzed using ...

Caltech scientists have built a record-breaking array of 6,100 neutral-atom qubits, a critical step toward powerful error-corrected quantum computers. The qubits maintained long-lasting superposition ...
