Quantum computers stand to revolutionize research by helping investigators solve certain problems exponentially faster than with conventional computers. Current quantum computers encounter a challenge where they lose stored information in a process known as quantum […]
Superconductors—materials that can conduct electricity without energy loss—are crucial for next-generation high-efficiency, ultrafast electronics. However, most superconductors share a critical limitation: they lose their superconducting properties in strong magnetic fields. In contrast, a class of […]
Physicists in China have simulated the effect of “false vacuum decay”: a phenomenon believed to play out constantly in the seemingly empty expanses of space, and which one theory even suggests could bring an abrupt […]
A new study, published in Physical Review Letters, reports that scientists have successfully imaged the formation of cavity-induced density waves induced by laser light in an ultracold quantum gas. Previously, only global signals, such as […]
A Majorana fermion is a particle that would be identical to its antiparticle. Such an object has not yet been found. However, certain solid materials exhibit analogous behavior as if Majorana fermions were present through […]
Crystals, bacterial colonies, flame fronts: the growth of surfaces was first described in the 1980s by the Kardar–Parisi–Zhang equation. Since then, it has been regarded as a fundamental model in physics, with implications for mathematics, […]
Researchers at ETH Zurich have realized particularly stable quantum logical operations with qubits made of neutral atoms. Since these operations, called quantum gates, are based on geometric phases, they are extremely robust against experimental noise […]
A new analysis reveals what happens when very short or narrow electron beams encounter a particle. The research is published in the New Journal of Physics. Scientists should be able to achieve a new level […]
Researchers at the Karlsruhe Institute of Technology (KIT) have reported important progress in quantum physics and materials science by optically initializing, controlling, and reading out nuclear spin states in a molecular material for the first […]
Mid-circuit measurements are one of the biggest practical hurdles in quantum error correction on encoded qubits. Researchers in Innsbruck and Aachen have now proposed and experimentally demonstrated that a universal fault-tolerant quantum algorithm can be […]
