Speaker today: Christopher Monroe (Duke University and IonQ, Inc.)
Trapped atomic ions are a leading physical platform for quantum computers,
featuring qubits with essentially infinite idle coherence times. Such atomic clock
qubits are controlled with laser beams, allowing densely-connected and
reconfigurable universal gate sets. The path to scale involves concrete
architectural paths, from shuttling ions between Quantum Processing Units
(QPU) cores to modular photonic interconnects between multiple QPUs.
Full-stack ion trap quantum computers have thus moved away from the physics
of qubits and gates and toward the engineering of optical control signals,
quantum gate compilation for algorithms, and software-defined error correction.
I will summarize the state-of-the-art in these quantum computers in both
academic and industrial settings, and speculate on how they might be used
for science and beyond.
Biography: Christopher Monroe is the Gilhuly Family Presidential Distinguished
Professor of Electrical and Computer Engineering and Physics, and Director of
the Duke Quantum Center at Duke University. Monroe is an atomic and quantum
physicist and engineer, with interests in fundamental quantum phenomena,
quantum information science, and quantum computer design and fabrication.
Monroe’s research group pioneered most aspects of ion trap quantum computers,
making the first steps toward a scalable, reconfigurable, and modular quantum
computer system. Monroe is also co-founder and Chief Scientist at IonQ, a public
company inside the Washington Beltway that builds quantum computers based
on trapped atomic ions. Monroe is a chief architect of the 2018 U.S. National
Quantum Initiative and is a member of the National Academy of Sciences.
