Waveguide-QED-based photonic quantum computation.
Abstract
We propose a new scheme for quantum computation using flying qubits--propagating photons
in a one-dimensional waveguide interacting with matter qubits. Photon-photon interactions
are mediated by the coupling to a four-level system, based on which photon-photon
π-phase gates (CONTROLLED-NOT) can be implemented for universal quantum computation.
We show that high gate fidelity is possible, given recent dramatic experimental progress
in superconducting circuits and photonic-crystal waveguides. The proposed system can
be an important building block for future on-chip quantum networks.

Harold U. Baranger
Professor of Physics
The broad focus of Prof. Baranger's group is quantum open systems at the nanoscale,
particularly the generation of correlation between particles in such systems. Fundamental
interest in nanophysics-- the physics of small, nanometer scale, bits of solid-- stems
from the ability to control and probe systems on length scales larger than atoms but
small enough that the averaging inherent in bulk properties has not yet occurred.
Using this ability, entirely unanticipated phenomena ca
Daniel J. Gauthier
Research Professor of Physics
Prof. Gauthier is interested in a broad range of topics in the fields of nonlinear
and quantum optics, and nonlinear dynamical systems.
In the area of optical physics, his group is studying the fundamental characteristics
of highly nonlinear light-matter interactions at both the classical and quantum levels
and is using this understanding to develop practical devices.
At the quantum level, his group has three major efforts in the area of quantum communication
and networking. I
