Piston control in a two-ion quantum device
Jing Li, E. Ya. Sherman, Andreas Ruschhaupt
We propose a scheme for piston control in a two-ion quantum device with motion confined to orthogonal axes. In this system, one ion plays the role of a ''classical'' piston driven…
Improved anharmonic trap expansion through enhanced shortcuts to adiabaticity
C. Whitty, A. Kiely, A. Ruschhaupt
Shortcuts to adiabaticity (STA) have been successfully applied both theoretically and experimentally to a wide variety of quantum control tasks. In previous work the authors have d…
Robustness of Enhanced Shortcuts to Adiabaticity in Lattice Transport
Chris Whitty, Anthony Kiely, Andreas Ruschhaupt
Shortcuts to adiabaticity (STA) are a collection of quantum control techniques that achieve high fidelity outside of the adiabatic regime. Recently an extension to shortcuts to adi…
Engineering atomic superradiance scaling in cavity QED system with collective and individual emission channels
Ruijin Sun, Xiang Guo, Andreas Ruschhaupt +1
The coherent emission of multiple atoms gives rise to superradiance, a cornerstone phenomenon in quantum optics with wide-ranging applications in quantum information processing and…
Fisher information from quantum many-particle arrival time measurements
Jukka Kiukas, Andreas Ruschhaupt
We formulate a quantum arrival time measurement process for a Bosonic many-particle system, with the aim of extracting statistical information on single-particle properties. The ar…
Maxwell demon no-go theorem for multichannel scattering
Andreas Ruschhaupt, Juan Gonzalo Muga
Recent implementations of Maxwell demons and other devices exhibiting asymmetric response to particles incident from opposite directions have raised conceptual and practical intere…
