Measuring outcome correlation for spin-s Bell cat-state and geometric phase induced spin parity effect
Yan Gu, Haifeng Zhang, Zhigang Song +2
In terms of quantum probability statistics the Bell inequality (BI) and its violation are extended to spin- entangled Schrödinger cat-state (called the Bell cat-state) with both…
Quantum gates implementations in the separated ion-traps by fast laser pulses
Miao Zhang, L. F. Wei
An approach is proposed to implement the universal quantum gates between the ions confined individually in the separated traps. Instead of the typical adiabatic operations, perform…
Joint quantum nondemolition measurements of qubits: beyond the mean-field theory
L. F. Wei, J. S. Huang, X. L. Feng +2
We propose an approach to nondestructively detect qubits by measuring the transmissions of a dispersively-coupled cavity. By taking into account all the cavity-qubits quantum c…
Entangling a series of trapped ions by moving cavity bus
Miao Zhang, H. Y. Jia, L. F. Wei
Entangling multiple qubits is one of the central tasks for quantum information processings. Here, we propose an approach to entangle a number of cold ions (individually trapped in…
Gain without inversion in quantum systems with broken parities
W. Z. Jia, L. F. Wei
For a quantum system with broken parity symmetry, selection rules can not hold and cyclic transition structures are generated. With these loop-transitions we discuss how to achieve…
Jaynes-Cummings Models with trapped surface-state electrons in THz cavities
Miao Zhang, H. Y. Jia, J. S. Huang +1
An electron floating on the liquid Helium is proposed to be trapped (by a micro-electrode set below the liquid Helium) in a high finesse cavity. Two lowest levels of the vertical m…
