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.

Ann Hamilton to Present Signature Lecture on April 16
The College of Arts & Letters is pleased to host National Medal of the Arts recipient, MacArthur Genius, and internationally acclaimed artist Ann Hamilton as part of the College’s Signature Lecture Series. The event, to be held virtually Friday, April 16, at 5 p.m., is free and open to the public, but registration is required. To register, please complete the registration form.
Ann Hamilton
Recognized for her large-scale multimedia installations, public projects, and performance collaborations, Hamilton is a Distinguished University Professor in the Department of Art at The Ohio State University.
Her large-scale installations often require expansive effort from many volunteers due to the sheer volume of material. The 1989 project,

Anybody who has had the opportunity to hear Michael Eric Dyson speak will tell you how powerful an experience it can be. That includes former President Barack Obama, who once said that anyone unlucky enough to follow him was sure to “pale in comparison.”
Fortunately for students at Arizona State University, where the famed author and one of America’s foremost public intellectuals will be paying a virtual visit to discuss his latest book, “Long Time Coming: Reckoning with Race in America,” they will only have to ask him questions.
