Fast and robust creation of an arbitrary single qubit state by nonadiabatic shortcut pulses in a three-level system
Ying Yan, Yi Chao Li, Adam Kinos +6
High-fidelity qubit initialization is of significance for efficient error correction in fault tolerant quantum algorithms. Combining two best worlds, speed and robustness, to achie…
Qubit gates with simultaneous transport in double quantum dots
Yi-Chao Li, Xi Chen, J. G. Muga +1
A single electron spin in a double quantum dot in a magnetic field is considered in terms of a four-level system. By describing the electron motion between the potential minima by…
Hamiltonian design to prepare arbitrary states of four-level systems
Y. - C. Li, D. Martínez, S. Martínez-Garaot +2
We propose a method to manipulate, possibly faster than adiabatically, four-level systems with time-dependent couplings and constant energy shifts (detunings in quantum-optical rea…
Shortcut to adiabatic population transfer in quantum three-level systems: effective two-level problems and feasible counter-diabatic driving
Yi-Chao Li, Xi Chen
Shortcut to adiabaticity in various quantum systems has attracted much attention with the wide applications in quantum information processing and quantum control. In this paper, we…
Experimental realization of stimulated Raman shortcut-to-adiabatic passage with cold atoms
Yan-Xiong Du, Zhen-Tao Liang, Yi-Chao Li +6
Accurate control of a quantum system is a fundamental requirement in many areas of modern science ranging from quantum information processing to high-precision measurements. A sign…
Pulse design without rotating wave approximation
S. Ibáñez, Yi-Chao Li, Xi Chen +1
We design realizable time-dependent semiclassical pulses to invert the population of a two-level system faster than adiabatically when the rotating-wave approximation cannot be app…
