Researchers have developed a means to realize cold-atom integrated nanophotonic circuits.
Researchers at Purdue University have trapped alkali atoms on an integrated photonic circuit, which behaves like a transistor for photons similar to electronic transistors. These trapped atoms demonstrate the potential to build a quantum network based on cold-atom integrated nanophotonic circuits.
The entire research team is based out of Purdue University in West Lafayette, Indiana. Hung served as principal investigator and supervised the project. Zhou performed the experiment to trap atoms on the integrated circuit, which was designed and fabricated in-house by Tzu-Han Chang, a former postdoc now working with Prof. Sunil Bhave at the Birck Nanotechnology Center.
"Unlike electronic transistors used in daily life, our atom-coupled integrated photonic circuit obeys the principles of quantum superposition," explains Hung."This allows us to manipulate and store quantum information in trapped atoms, which are quantum bits known as qubits.
