### Machine Learning Aids Classical Modeling of Quantum Systems

By using “classical shadows,” ordinary computers can beat quantum computers at the tricky task of understanding quantum behaviors.

### Physicists Observe ‘Unobservable’ Quantum Phase Transition

Measurement and entanglement both have a “spooky” nonlocal flavor to them. Now physicists are harnessing that nonlocality to probe the spread of quantum information and control it.

### New Codes Could Make Quantum Computing 10 Times More Efficient

Quantum computing is still really, really hard. But the rise of a powerful class of error-correcting codes suggests that the task might be slightly more feasible than many feared.

### Does Nothingness Exist?

Even empty space bubbles with energy, according to quantum mechanics — and that fact affects almost every facet of physical reality. The theoretical physicist Isabel Garcia Garcia explains to Steven Strogatz why it’s so important in modern physics to understand what a true vacuum is.

### How Quantum Physicists Explained Earth's Weather Patterns

By treating Earth as a topological insulator — a state of quantum matter — physicists found a powerful explanation for the movements of the planet’s air and seas.

### The Physicist Who’s Challenging the Quantum Orthodoxy

For decades, physicists have struggled to develop a quantum theory of gravity. But what if gravity — and space-time — are fundamentally classical?

### In New Paradox, Black Holes Appear to Evade Heat Death

The puzzling behavior of black hole interiors has led researchers to propose a new physical law: the second law of quantum complexity.

### The Physicist Who Glues Together Universes

Renate Loll has helped pioneer a radically new approach to quantum gravity. She assumes that the fabric of space-time is a blend of all possible fabrics, and she has developed the computational tools needed to calculate the far-reaching implications of that assumption.

### Physicists Create Elusive Particles That Remember Their Pasts

In two landmark experiments, researchers used quantum processors to engineer exotic particles that have captivated physicists for decades. The work is a step toward crash-proof quantum computers.
