If one monitors the state of a quantum system continuously, it will be seen to “jump” between its quantum states. Daniel’s thesis, Quantum Jumps and Measurement Backaction in a Superconducting Qubit, reported the first observation of such quantum jumps in a macroscopic quantum system, a superconducting electrical circuit. The techniques he developed can be used for quantum feedback and error correction, ultra-sensitive magnetometry, and quantum-limited microwave amplification. Daniel is currently an NRC Postdoctoral Fellow at NIST in Boulder, Colorado, working on quantum computing and precision sensing and metrology applications with trapped ions. He is also interested in developing interfaces between trapped ions and other quantum systems. Outside the lab, Daniel is an avid runner and skier and loves playing with his baby son.
