Quantum brachistochrone curves as geodesics: obtaining accurate control protocols for time-optimal quantum gates

Xiaoting Wang, Michele Allegra, Kurt Jacobs +3

Most methods of optimal control cannot obtain accurate time-optimal protocols. The quantum brachistochrone equation is an exception, and has the potential to provide accurate time-…

Adiabatic tracking of quantum many-body dynamics

Hamed Saberi, Tomáš Opatrný, Klaus Mølmer +1

The nonadiabatic dynamics of a many-body system driven through a quantum critical point can be controlled using counterdiabatic driving, where the formation of excitations is suppr…

Quantum feedback: theory, experiments, and applications

Jing Zhang, Yu-xi Liu, Re-Bing Wu +2

The control of individual quantum systems is now a reality in a variety of physical settings. Feedback control is an important class of control methods because of its ability to re…

Comparing resolved-sideband cooling and measurement-based feedback cooling on an equal footing: analytical results in the regime of ground-state cooling

Kurt Jacobs, Hendra I. Nurdin, Frederick W. Strauch +1

We show that in the regime of ground-state cooling, simple expressions can be derived for the performance of resolved-sideband cooling --- an example of coherent feedback control -…

SIC-POVMs and Compatibility among Quantum States

Blake C. Stacey

An unexpected connection exists between compatibility criteria for quantum states and symmetric informationally complete POVMs. Beginning with Caves, Fuchs and Schack's "Conditions…

Equivalent definitions of the quantum nonadiabatic entropy production

Jordan M. Horowitz, Takahiro Sagawa

The nonadiabatic entropy production is a useful tool for the thermodynamic analysis of continuously dissipating, nonequilibrium steady states. For open quantum systems, two seeming…

Some Negative Remarks on Operational Approaches to Quantum Theory

Christopher A. Fuchs, Blake C. Stacey

Over the last 10 years there has been an explosion of "operational reconstructions" of quantum theory. This is great stuff: For, through it, we come to see the myriad ways in which…
