Will Better Superconductors Transform the World?

May 9, 2024

Scientists are pursuing materials that can conduct electricity with perfect efficiency under ambient conditions. In this episode, the physicist Siddharth Shanker Saxena tells co-host Janna Levin about what makes this hunt so difficult and consequential.

Scientists Find a Fast Way to Describe Quantum Systems

May 1, 2024

After years of false starts, a team of computer scientists has found a way to efficiently deduce the Hamiltonian of a physical system at any constant temperature.

Can Information Escape a Black Hole?

April 11, 2024

Black holes are inescapable traps for most of what falls into them — but there can be exceptions. The theoretical physicist Leonard Susskind speaks with co-host Janna Levin about the black hole information paradox and how it has propelled modern physics.

What Is Quantum Teleportation?

March 14, 2024

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.

Physicists Finally Find a Problem That Only Quantum Computers Can Do

March 12, 2024

Researchers have shown that a problem relating to the energy of a quantum system is easy for quantum computers but hard for classical ones.

What Is the Nature of Time?

February 29, 2024

Time is all around us: in the language we use, in the memories we revisit and in our predictions of the future. But what exactly is it? The physicist and Nobel laureate Frank Wilczek joins Steve Strogatz to discuss the fundamental hallmarks of time.

A Quantum Trick Implied Eternal Stability. Now the Idea May Be Falling Apart.

February 26, 2024

A series of advances seemed to promise the impossible: the existence of quantum states that would never, ever fall into disarray. But physicists are now discovering that the pull of disorder may not be so easily overcome.

New Kind of Magnetism Spotted in an Engineered Material

January 10, 2024

In an atomically thin stack of semiconductors, a mechanism unseen in any natural substance causes electrons’ spins to align.

The Year in Computer Science

December 20, 2023
