The key question: what computation should be performed? A team of researchers is suggesting that computing the state of a random quantum circuit that exhibits chaotic behavior would be perfect for the task. Let’s delve into why that might be.

In 1981, Richard Feynman suggested that a quantum computer might be able to simulate the evolution of quantum systems much better than classical computers. Except for several proof-of-principle experiments, no working quantum computer has yet been built.

MIT, Harvard, and LBNL physicists have discovered a new quantum electronic material, the “kagome metal,” whose atomic structure resembles a Japanese basketweaving pattern and exhibits exotic, quantum behavior.

To say the quantum world is unintuitive is a staggering understatement. Particles end up in more than one place at a time, and the instances interact with each other. Decisions made after a photon has traversed an obstacle course determine the path it took through it.
