A Diamond Speck in Two Places at Once ⚡ экспресс
A proposed chip-based system uses current loops to levitate a nanodiamond containing an NV center and coax it into a spatial superposition. With masses between 10⁻¹⁹ and 10⁻¹⁵ kg, the setup can split the particle by distances of ~1 nm to ~10 µm in under 0.1 seconds, starting from the center of a diamagnetic trap. The design features two parallel chips that levitate the diamond and generate superposition along the x-axis, while tightly confining it along y and against gravity (z). Numerical simulations, assuming Gaussian starting conditions, confirm a stable one-dimensional superposition—levitation steady, lateral drift minimal. This paves the way for tabletop Schrödinger’s cat experiments to test the quantum gravity entanglement of masses (QGEM) proposal.
A tiny diamond, smaller than a dust speck, hovers inside a magnetic trap made of microchips. Inside the crystal is a single defect acting as a beacon. Scientists coax the diamond into being in two places at once, like a magician’s ball that honestly rests under two cups.
This isn't just a trick. This splitting, or superposition, allows testing a protocol: if two such diamonds become entangled through gravitational attraction, then space-time itself is made of quantum cells. The experiment fits on a table, yet it could unite quantum mechanics with Einstein’s theory of relativity—a bridge between worlds where particle physics currently falls short.
🎯 The state of dual existence lasts less than an instant—a tenth of a second—but that’s long enough for measurements.
