Turning a Quantum Computer into a Time Crystal
Google’s Sycamore quantum processor can simulate an elusive quantum system called a discrete-time crystal.
From Coordination to Collapse in Rigged Economies
A game-theoretical model of a rigged economy predicts the emergence of cartels followed by a risk of instability as the economy becomes more complex.
Toward Skin-Like Electronics
A technique that allows researchers to fabricate 42,000 elastic transistors per square centimeter takes them a step closer to creating electronic devices that look and behave like skin.
A Way to Experimentally Test String Theory’s “Fuzzball” Prediction
Simulations reveal the gravitational-wave signal of string theory’s “fuzzy” black holes, a signature that researchers could potentially measure.
A Scalable Code for Reducing Quantum Errors
A new scheme could offer a technologically viable solution for remedying computational errors in near-term quantum devices.
Long-Range Spin Currents with Chiral Crystals
Chiral crystals can produce spin-polarized currents that propagate over tens of micrometers — a promising feature for application in spintronics devices.
Superpositions of Chiral Molecules
Matter-wave diffraction can put chiral molecules into superpositions of left- and right-handed forms, enabling new studies of how the two states interact with their environment.
