IBM quantum computer accurately simulates magnetic material — and verified against real physics experiment

  • One response
For the first time, IBM researchers and their partners from leading universities have succeeded in performing a quantum simulation of a magnetic material whose accuracy has been tested against the material's behavior in nature, an important step towards making quantum computing a practical tool in materials science.

Anthony Leggett (1938–2026): Nobel laureate who worked at the forefront of quantum physics

  • One response
Avshalom Elitzur bid farewell to Anthony James Leggett, winner of the 2003 Nobel Prize in Physics, and recalled his personal meetings with him, his contribution to the study of superconductors and superfluids, and his part in shaping the discussion on the foundations of quantum theory.

Australian research team discovers why quantum computers have “memory problems” over time

  • One response
Researchers have found that the tiny errors that plague quantum computers don't appear randomly. Instead, they can remain in the computer, evolve over time, and even connect with each other across time.
