Engineers have built an 'anti-qubit' — a superconducting qubit that behaves like an electron moving backward in time. By linking it with a regular qubit, they obtained a detector capable of sensing an unknown field with ideal precision. In the future, this will lead to ultra-sensitive quantum navigators and medical sensors.
🎯 Positrons aren't just in formulas: they are used daily in PET scanners to illuminate cancer tumors.
🎬 Sci-fi writers love plots with reverse time flow, but scientists have turned this idea into a working tool for perfect quantum measurements.
