Quantum Feedback Control of Atomic Motion in an Optical Cavity
Daniel A. Steck, Kurt Jacobs, Hideo Mabuchi +2
We study quantum feedback cooling of atomic motion in an optical cavity as a prototypical nonlinear quantum control problem. We design a feedback algorithm that can cool the atom t…
The transition to classical chaos in a coupled quantum system through continuous measurement
Shohini Ghose, Paul Alsing, Ivan Deutsch +3
Continuous observation of a quantum system yields a measurement record that faithfully reproduces the classically predicted trajectory provided that the measurement is sufficiently…
Efficient measurements, purification, and bounds on the mutual information
Kurt Jacobs
When a measurement is made on a quantum system in which classical information is encoded, the measurement reduces the observers average Shannon entropy for the encoding ensemble. T…
On the properties of information gathering in quantum and classical measurements
Kurt Jacobs
The information provided by a classical measurement is unambiguously determined by the mutual information between the output results and the measured quantity. However, quantum mec…
Feedback cooling of a nanomechanical resonator
Asa Hopkins, Kurt Jacobs, Salman Habib +1
Cooled, low-loss nanomechanical resonators offer the prospect of directly observing the quantum dynamics of mesoscopic systems. However, the present state of the art requires cooli…
How to project qubits faster using quantum feedback
Kurt Jacobs
When one performs a continuous measurement, whether on a classical or quantum system, the measurement provides a certain average rate at which one becomes certain about the state o…
