Quantum physics

One of the quantum fields that fills the universe is special because its default value seems poised to eventually change, changing everything.

Electrons have been seen uniting into entities with fractions of electric charge, this time without a magnetic field coaxing them into it.

Particle physicists in search of the next theory of reality are consulting a mathematical structure that they know will never fail: a table of possibilities known as the S-matrix.

Alex Sushkov is updating an old technology with new quantum tricks in hopes of sensing the magnetic influence of dark matter.

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.

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.

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.

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.

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