A Molecule-Sized Quantum Optical Transistor
A Swiss team has shrunk the transistor nearly as far as it can go: to the size of one dye molecule.
Over the past 60 years, ever-smaller transistors have revolutionized electronics and computing. Now, a Swiss team has shrunk the transistor nearly as far as it can go: to the size of one dye molecule. The tiny transistor is attenuating or amplifying an optical signal as directed by a second “gate” beam of light (Nature 460, 76).
