About us
About us
We are an experimental quantum optics shop with a strong quantum information bias. We're based at the U. of Virginia, where we have been pursuing the implementation of quantum computing with light since 2004. Progress along these lines has made us develop unique expertise in generating quantum entanglement over very large scales in the lab. Our other line of effort is the generation and complete characterization of highly exotic, deemed "non Gaussian," quantum states of light, which are critical for quantum error correction and for the exponential speedup of a quantum computer.
