Tiny Crystal Measures Temperature and Magnetic Field Simultaneously ⚡ экспресс
Original: "On chip, multifunctional quantum sensing using single spins in a van der Waals crystal"
A microscopic flaw in a transparent crystal works as a two-way sensor: its color reveals temperature, while its blinking rhythm tracks magnetic fields.

A tiny crystal defect works as a thermometer and compass in one: heat shifts its color, magnetism changes its brightness. These dual-mode quantum sensors will let us monitor chip overheating and read magnetic signals in the brain.
🎯 Single defects in boron nitride can be glued to the end of an optical fiber — making a thermometer-magnetometer as thin as a human hair.
🎬 Such a sensor is almost a tricorder from Star Trek: a tiny gadget that measures temperature and magnetic fields at the same time.
