Abstract: Ultra-cold atomic gases can now be precisely controlled and manipulated in the quantum regime. In this talk, I will present our results on using ensembles of cold atoms, especially high-lyi...
Abstract: Research for cooling and trapping of atoms in the mid 1980s was mainly motivated to enable precise spectroscopic measurement. However, perturbation by the trapping force introduces sig-nifi...
Abstract: We propose two platforms for realizing macroscopic qubits in spintronics devices. The first prototype magnetic quantum information processing device, based on spin superfluidity and spin Ha...
Abstract: Highly excited Rydberg atoms exhibit strong and long-range interactions, opening new possibilities for scalable quantum information processing. In terms of qubits control, Rydberg atom arra...
Abstract: We demonstrate a coherent and dynamic beam splitter based on light storage in cold atoms. An input weak laser pulse is first stored in a cold atom ensemble via electromagnetically induced t...
Quantum information protocols, originally envisioned for two-state (qubit) systems, have also been extended to continuous variables (CVs). It is usually held that Gaussian squeezed state is an essenti...
