Measurement operator for quantum nondemolition measurements
Ebubechukwu O. Ilo-Okeke, Ping Chen, Shuang Li +3
We derive a measurement operator corresponding to a quantum nondemolition (QND) measurement of an atomic ensemble. The quantum measurement operator takes the form of a positive ope…
Macroscopic quantum information processing using spin coherent states
Tim Byrnes, Daniel Rosseau, Megha Khosla +6
Previously a new scheme of quantum information processing based on spin coherent states of two component Bose-Einstein condensates was proposed (Byrnes {\it et al.} Phys. Rev. A 85…
Theory of single-shot phase contrast imaging in spinor Bose-Einstein condensates
Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We introduce a theoretical framework for single-shot phase contrast imaging (PCI) measurements of spinor Bose-Einstein condensates. Our model allows for the simple calculation of t…
Geometric phase gate for entangling two Bose-Einstein condensates
Mahmood Irtiza Hussain, Ebubechukwu O. Ilo-Okeke, Tim Byrnes
We propose a method of entangling two spinor Bose-Einstein condensates using a geometric phase gate. The scheme relies upon only the ac Stark shift and a common controllable optica…
