In Hilbert Space, All Things Are Quantumly Possible
To explore quantum phenomena, we must leave the familiar world and enter the abstract realm of Hilbert space.
Graduate Student Proves a Quantum Uncertainty Principle for Fractals
The math, which combines chaos, quantum theory, and infinitely complex fractal structures, has been called a “foundational result.”
Physicists Solve a Big Quantum Mystery. Now, Old Results Don’t Add Up.
New calculations seem to have put a 25-year-old particle physics puzzle to rest. But they’ve also created a clash with other experimental results.
How Many Elementary Particles Are There, Really?
Plausible answers range from 17 to — in all seriousness — 995.5.
Entanglement Builds Space-Time. Now “Magic” Gives It Gravity.
In holographic theories, physicists may have traced the pliability of space-time to its quantum roots: a measure of quantumness known as “magic.”
Key Chemistry Question Answered, No Quantum Computer Required
Do we need quantum computers to fully understand complex chemical reactions? A new result, decades in the making, shows the surprising power of ordinary “classical” machines.
Quantum ‘Jamming’ Explores the Truly Fundamental Principles of Nature
Some quantum cryptographers want to find ways to keep messages secret even if the rules of quantum mechanics don’t hold. The recently rediscovered idea of quantum jamming complicates things.
A Through-The-Lens Look at the World’s Particle Physics Labs
The winning entries in the 2025 Global Physics Photowalk contest showcase the beauty of toil and discovery.
Quantum Cryptography Pioneers Win Turing Award
Charles Bennett and Gilles Brassard were recognized for their foundational work in quantum information science.
