Center for Computational Quantum Physics Neural Networks and ‘Ghost’ Electrons Accurately Reconstruct Behavior of Quantum Systems By Thomas Sumner

Physicists at the Flatiron Institute’s Center for Computational Quantum Physics and their collaborators have created a new way to simulate quantum entanglement between interacting particles. Their approach involves adding extra, fictitious particles controlled by an artificial intelligence technique called a neural network.

Collaborative Work

Structural and Molecular Biophysics Collaboration

Underlying all biological processes are molecules and their interactions with each other. However, our ability to understand how these molecules function over biologically relevant scales remains very limited.

Max Planck-New York Center for Nonequilibrium Quantum Phenomena

Columbia University, the Flatiron Institute in New York City and the Max Planck Society in Germany have created a partnership, called the Center for Nonequilibrium Quantum Phenomena.
