Quantum communication and computation in quantum optics

Harry J. Kimble, J. R. Buck, Christopher A. Fuchs +9 more

Summary form only given. In the quantum optics group at Caltech, we are attempting to lay the foundations for quantum information science by way of advances on several fronts in optical physics. Within the setting of cavity QED, single atoms are strongly coupled to the field of a high finesse optical cavity at the single photon level, with current work directed toward trapping and localization of atoms inside the cavity. Although there are daunting technical problems to overcome, a principal scientific objective is the creation of quantum networks to implement fundamental quantum communication protocols and for distributed quantum computation. Beyond quantum information processing with internal atomic states and photons serving as qubits, we are also investigating algorithms for continuous quantum variables. A recent example is our realization of quantum teleportation for the quadrature amplitudes of a beam of light. The experiment utilizes squeezed-state entanglement to achieve unconditional quantum teleportation.

Strong Interactions of Single Atoms and Photons in Cavity QED

Harry J. Kimble

An important development in modern physics is the emerging capability for investigations of dynamical processes for open quantum systems in a regime of strong coupling for which individual quanta play a decisive role. Of particular significance in this context is research in cavity quantum electrodynamics which explores quantum dynamical processes for individual atoms strongly coupled to the electromagnetic field of a resonator. An overview of the research activities in the Quantum Optics Group at Caltech is presented with an emphasis on strong coupling in cavity QED which enables exploration of a new regime of nonlinear optics with single atoms and photons.

The Critical Role of Chemistry in Advancing Quantum Information Science

Linda Nhon, Theodore G. Goodson III

Advancements in the field of Quantum Information Science (QIS) are expected to produce groundbreaking technologies in computing, sensing, and communications. These developments could have an impact on the economy and workforce of the United States. In order to achieve this vision and sustain U.S. leadership in QIS, however, a robust research enterprise needs to be established. Presently, QIS has reached an inflection point for new discoveries; searching for novel quantum molecular materials that are operational, practical, and efficient is now the new frontier. Since chemistry is the study of manipulating molecular properties across different lengths and time-scales, it has a tremendous opportunity to take a leading role in this untapped domain. Blending QIS and chemistry together will accelerate progress in designing new quantum molecular materials, developing novel measurement tools and techniques, and establishing new quantum computing standards. A recent National Academies of Sciences, Engineering, and Medicine (NASEM) report, Advancing Chemistry and Quantum Information Science, points to fundamental research areas at the interface of these two disciplines that should be pursued in the near-term. Here, a brief overview of these research directions as well as collaboration and infrastructure needs identified from the report are presented.
