A new path toward sending and receiving information with single photons of light has been discovered by an international team of researchers led by the University of Michigan.
Their experiment demonstrated the possibility of using an effect known as nonlinearity to modify and detect extremely weak light signals, taking advantage of distinct changes to a quantum system to advance next generation computing.
Today, as silicon-electronics-based information technology becomes increasingly throttled by heating and energy consumption, nonlinear optics is under intense investigation as a potential solution. The quantum egg carton captures and releases photons, supporting excited quantum states while it possesses the extra energy. As the energy in the system rises, it takes a bigger jump in energy to get to that next excited state that s the nonlinearity.

Cascade laser backed for real-time nitrogen sensing in wastewater
03 Mar 2021
E. coli may follow.
Texas-based photonics company Max-IR Labs has won $750,000 in Small Business Innovation Research (SBIR) funding to develop a prototype nitrogen sensor based around a quantum cascade laser (QCL) source.
The Dallas firm says that the âPhase IIâ grant - awarded via the US National Science Foundation - will also support initial field tests of the device, which promises to reduce the energy costs associated with a critical wastewater treatment step by 20Â per cent or more.
Using Max-IRâs proprietary âIon Selective Materials using Infrared Radiationâ (ISMIR) technique, the novel approach should be able to monitor pollutants like nitrates, nitrites, and ammonia in real time.
