Approaching Carnot Efficiency at Finite Power in an Experimentally Feasible Quantum Heat Engine
Shogo Toma, Atsushi Noguchi, Ken Funo +1
Whether a heat engine can approach Carnot efficiency while maintaining finite power is a fundamental question in finite-time thermodynamics. For classical Markovian heat engines wi…
Quantum Logic Spectroscopy of an Electron and Positron for Precise Tests of the Standard Model
Xing Fan, Atsushi Noguchi, Kento Taniguchi
We propose a scheme for quantum logic spectroscopy of an electron or positron in a Penning trap. An electron or positron in a spectroscopy trap is coupled to a remote logic electro…
Semi-Analytical Engineering of Strongly Driven Nonlinear Systems Beyond Floquet and Perturbation Theory
Kento Taniguchi, Atsushi Noguchi, Takashi Oka
Strongly driven nonlinear systems are frequently encountered in physics, yet their accurate control is generally challenging due to the intricate dynamics. In this work, we present…
Image Current Detection of Electrons in a Room-Temperature Paul Trap
Kento Taniguchi, Atsushi Noguchi
We report the image current detection of electrons in a room-temperature Paul trap at microwave frequencies. By selectively leveraging distinct cavity modes for trapping and detect…
Numerical Investigations of Electron Dynamics in a Linear Paul Trap
Andris Huang, Edith Hausten, Qian Yu +6
Trapped electrons have emerged as an interesting platform for quantum information processing due to their light mass, two-level spin states, and potential for fully electronic mani…
