Quantum computers could enable physicists to tackle questions even the most powerful computers cannot handle.

Scientists are exploring a variety of ways to make quantum bits. We may not need to settle on a single one.

Quantum information breaks the rules of classical information in a way that could allow us to answer questions that a classical computer cannot.

Quantum computers go beyond the binary.

Inventions like the transistor and laser changed the world. What changes will the second quantum revolution bring?

Uncertainty, entanglement, spooky action: On the quantum scale, the universe doesn’t work the way you might expect.

This month, Symmetry presents a series of articles on the past, present and future of quantum research—and its many connections to particle physics, astrophysics and computing.

For years, scientists have wondered how the observed afterglow of the Big Bang relates to the distribution of galaxies in our universe. Now, thanks to a new map of dark matter, they have direct evidence that a cold region in the afterglow coincides with the lack of matter in the same patch of the sky.

Scientists at the Fermilab-led Superconducting Quantum Materials and Systems Center have discovered that nanohydrides, variants of an imperfection found in advanced superconducting materials for particle accelerators, also affect industrially produced superconducting qubits.

As part of the international Deep Underground Neutrino Experiment, a UK-US collaboration is preparing for industrial scale production of large particle detector components. This fall, it’s taking the first ones for a final test-drive.
