Guiding cesium atoms along a 420-nanometer fiber lets a quantum motion sensor keep working through jolts that would break a free-falling version. A new silicon-pinned membrane design solves the heat problem that stalled the idea for decades.
The levitated sensor can register a nudge one-hundredth the width of an atom. Over a month of quiet nights it saw nothing — and that silence rules out a swath of ultraheavy dark matter nine orders of magnitude wide.
The device hits 32 femtoteslas per root hertz at room temperature — no liquid helium, no shielded room. The trick was killing 70% of the thermal noise with a graphite plate.
University of Chicago researchers discovered an elegant way to generate complex entangled quantum states without complicated hardware, potentially advancing quantum computing and sensing technologies.
A University of Chicago team showed that giving paired atoms opposite energy shifts can conjure complex entangled states using only standard lab tools and tunable lasers.
A superconducting calorimeter at Aalto University detected just 0.83 zeptojoules — a sensitivity that could sharpen quantum computers and even help hunt for dark matter.
By combining two precisely controlled forces on a single trapped ion, researchers demonstrated an elusive way to manipulate quantum uncertainty that could expand quantum sensing and computing.
By layering two non-commuting forces on a single calcium ion, the team can flip a quantum oscillator between standard squeezing, trisqueezing and quadsqueezing in microseconds, unlocking a new toolkit for quantum sensing, simulation and bosonic error correction.
