Quantum Entanglement Doubles Microscope Precision.
Researchers at Caltech have developed a new technique called quantum microscopy by coincidence, which utilizes quantum entanglement to double the resolution of light microscopes. The entanglement of photons results in a shorter wavelength, allowing for greater resolution without damaging specimens such as living cells. The team built an optical apparatus that used a special crystal to convert photons into biphotons and demonstrated microscopic resolution and cell imaging with their innovative system.
