Speaker: Daniel Slichter
Host: Nick Bronn, PhD.
Trapped atomic ions are a leading quantum platform, offering excellent coherence properties, high-fidelity qubit control and readout, and reconfigurable qubit connectivity. Qubit state control is typically performed using laser beams delivered to the ions via free-space optics, and readout generally relies on ion fluorescence photon collection using high-numerical-aperture objectives. Both of these methods perform well, but present challenges for scaling to large numbers of qubits. In my talk, I will describe some of our efforts toward integrating both control and readout functionality into microfabricated ion trap chips, opening potential avenues for improved scalability.

Daniel Slichter is a staff physicist at NIST in Boulder, CO. His research focuses on quantum information experiments with trapped atomic ions, with an emphasis on developing new paradigms for scalable trapped ion quantum computing and networking. Among other projects, he and his team are developing microwave- and rf-based techniques to perform high-fidelity control and entanglement of trapped ion qubits, along with trap-integrated photon detectors for qubit readout. Before coming to NIST, he conducted research in superconducting quantum information at UC Berkeley, where he performed the first continuous high-fidelity measurement of a superconducting qubit and studied quantum feedback and measurement backaction. These breakthroughs relied on the development and use of near-quantum-limited microwave-frequency superconducting parametric amplifiers.
Dr. Slichter received an A.B. in physics from Harvard University (2004), and an M.A. (2007) and Ph.D. (2011) in physics from the University of California, Berkeley. He was the recipient of a Hertz Foundation Fellowship (2006-2011), the Hertz Foundation Thesis Prize (2012), an NRC Postdoctoral Fellowship (2012-2014), and a Kavli Fellowship (2016). He currently serves as an Associate Editor for IEEE Transactions on Quantum Engineering.
