Quantum computers are incredible, but they come with a big challenge: keeping errors under control. At the heart of the issue is the qubit—the quantum version of a bit. While qubits are key to quantum ...

You might be familiar with the qubit, the fundamental unit of quantum information. As its name suggests, a qubit in a quantum computer performs the same function as a bit in a classical computer, with ...

Princeton physicists have discovered an abrupt change in quantum behavior while experimenting with a three-atom-thin insulator that can be easily switched into a superconductor. The research promises ...

One of the quantum fields that fills the universe is special because its default value seems poised to eventually change, changing everything. Vacuum decay, a process that could end the universe as we ...

When quantum spins interact, they can produce collective behaviors that defy long-standing expectations. Researchers have now shown that the Kondo effect behaves very differently depending on spin ...
