On Approaching the Ultimate Limits of Photon-Efficient and Bandwidth-Efficient Optical Communication
Sam Dolinar, Kevin M. Birnbaum, Baris I. Erkmen +1
It is well known that ideal free-space optical communication at the quantum limit can have unbounded photon information efficiency (PIE), measured in bits per photon. High PIE come…
Cavity QED with Multiple Hyperfine Levels
K. M. Birnbaum, A. S. Parkins, H. J. Kimble
We calculate the weak-driving transmission of a linearly polarized cavity mode strongly coupled to the D2 transition of a single Cesium atom. Results are relevant to future experim…
Theory of Photon Blockade by an Optical Cavity with One Trapped Atom
K. M. Birnbaum, A. Boca, R. Miller +3
In our recent paper [1], we reported observations of photon blockade by one atom strongly coupled to an optical cavity. In support of these measurements, here we provide an expande…
Strategies for Real-Time Position Control of a Single Atom in Cavity QED
T. W. Lynn, K. Birnbaum, H. J. Kimble
Recent realizations of single-atom trapping and tracking in cavity QED open the door for feedback schemes which actively stabilize the motion of a single atom in real time. We pres…
Observation of the Vacuum-Rabi Spectrum for One Trapped Atom
A. Boca, R. Miller, K. M. Birnbaum +3
The transmission spectrum for one atom strongly coupled to the field of a high-finesse optical resonator is observed to exhibit a clearly resolved vacuum-Rabi splitting characteris…
