Elizabeth Goldschmidt: Quantum information with photons

Assistant Professor of Physics
University of Illinois at Urbana-Champaign

Quantum information has the potential to be a transformative technology in the coming decades enabling secure information sharing, fundamental metrological advantages, and massive computational speedup for some classically intractable problems. Light plays an important role in many quantum information systems, particularly for transmitting quantum bits, or qubits. I will give a broad overview of the role that optical photons can play in quantum computing and quantum networking. This includes a discussion of generating light that is suitable for quantum information applications, inducing effective interactions between photons to enable entangling operations, and engineering light-matter interfaces for reversible mapping of quantum information. I will highlight recent experimental results to illustrate all of these research goals.
