Tunable one-dimensional microwave emissions from cyclic-transition three-level atoms
W. Z. Jia, L. F. Wei, Z. D. Wang
By strongly driving a cyclic-transition three-level artificial atom, demonstrated by such as a flux-based superconducting circuit, we show that coherent microwave signals can be ex…
High efficiency tomographic reconstruction of quantum states by quantum nondemolition measurements
J. S. Huang, L. F. Wei, C. H. Oh
We propose a high efficiency tomographic scheme to reconstruct an unknown quantum state of the qubits by using a series of quantum nondemolition (QND) measurements. The proposed QN…
Vacuum induced Berry phases in single-mode Jaynes-Cummings models
Yu Liu, L. F. Wei, W. Z. Jia +1
Motivated by the work [Phys. Rev. Lett. 89, 220404 (2002)] for detecting the vacuum-induced Berry phases with two-mode Jaynes-Cummings models (JCMs), we show here that, for a param…
Distinguishing left- and right-handed molecules by two-step coherent pulses
W. Z. Jia, L. F. Wei
Chiral molecules with broken parity symmetries can be modeled as quantum systems with cyclic-transition structures. By using these novel properties, we design two-step laser pulses…
Quantum state engineering with flux-biased Josephson phase qubits by Stark-chirped rapid adiabatic passages
W. Nie, J. S. Huang, X. Shi +1
In this paper, the scheme of quantum computing based on Stark chirped rapid adiabatic passage (SCRAP) technique [L. F. Wei et al., Phys. Rev. Lett. 100, 113601 (2008)] is extensive…
