Quantum trick: by deliberately distorting the signal, scientists hear it better. Error correction usually fixes glitches, but here it sifts out noise, leaving a faint echo that reveals hidden signals. This can capture whispers from the early Universe or barely noticeable nudges of dark matter.
🎯 This method grew out of the fight against errors in quantum computing. Its transfer to the sensor domain was so non-obvious that the idea was initially rejected as contradicting the logic of amplification.
