Lasers Manipulate Quantum Dots for Cryptography
Researchers at the National Institute of Standards and Technology and the Joint Quantum Institute have measured, for the first time, the complete biexciton-exciton emission spectrum of a single quantum.
Experimental set up. Orienting the resonant laser at a right angle to the quantum dot light minimizes scattering.
Cross-section scanning tunneling microscope image shows InAs quantum dots—about 30 nm long—embedded in gallium arsenide.
Researchers at the National Institute of Standards and Technology (NIST) and the Joint Quantum Institute (JQI) have measured, for the first time, the complete biexciton-exciton emission spectrum of a single quantum. Their system was able to generate single or entangled photons (Phys. Rev. Lett. 101, 027401).
