### The Best Qubits for Quantum Computing Might Just Be Atoms

In the search for the most scalable hardware to use for quantum computers, qubits made of individual atoms are having a breakout moment.

### What Is Quantum Teleportation?

Teleporting people through space is still science fiction. But quantum teleportation is dramatically different and entirely real. In this episode, Janna Levin interviews the theoretical physicist John Preskill about teleporting bits and the promise of quantum technology.

### Never-Repeating Tiles Can Safeguard Quantum Information

Two researchers have proved that Penrose tilings, famous patterns that never repeat, are mathematically equivalent to a kind of quantum error correction.

### New Calculations Show How to Escape Hawking’s Black Hole Paradox

Inside of a black hole, the two theoretical pillars of 20th-century physics appear to clash. Now a group of young physicists think they have resolved the conflict by appealing to the central pillar of the new century — the physics of quantum information.

### 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.

### Wormhole Experiment Called Into Question

Last fall, a team of physicists announced that they had teleported a qubit through a holographic wormhole in a quantum computer. Now another group suggests that’s not quite what happened.

### Physicists Use Quantum Mechanics to Pull Energy out of Nothing

The quantum energy teleportation protocol was proposed in 2008 and largely ignored. Now two independent experiments have shown that it works.

### New Algorithm Closes Quantum Supremacy Window

Random circuit sampling, a popular technique for showing the power of quantum computers, doesn’t scale up if errors go unchecked.

### Physicists Create a Holographic Wormhole Using a Quantum Computer

The unprecedented experiment explores the possibility that space-time somehow emerges from quantum information.
