Ultralow-energy electron scattering from alkaline-earth atoms: the scattering-length limit
We use the non-relativistic R-matrix method to treat ultralow-energy electron scattering from the alkaline-earth atoms Mg, Ca, and Sr. The sensitivity of the predictions for the scattering length is analysed by comparing results obtained from a variety of structure and collision models. We estimate the electron scattering lengths to be −2.5 a0 for e−–Mg, −12 a0 for e−–Ca, and −18 a0 for e−–Sr, ...
متن کاملQuantum computing with alkaline-Earth-metal atoms.
We present a complete scheme for quantum information processing using the unique features of alkaline-earth-metal atoms. We show how two completely independent lattices can be formed for the 1S0 and 3P0 states, with one used as a storage lattice for qubits encoded on the nuclear spin, and the other as a transport lattice to move qubits and perform gate operations. We discuss how the 3P2 level c...

در این پایان نامه، درهمتنیدگی بین یک سیستم نقطه کوانتومی دوگانه(مولکول نقطه کوانتومی) و میدان مورد مطالعه قرار گرفته است. از آنتروپی ون نیومن به عنوان ابزاری برای بررسی درهمتنیدگی بین اتم و میدان استفاده شده و تاثیر پارامترهای مختلف، نظیر تونل زنی(که توسط تغییر ولتاژ ایجاد می شود)، شدت میدان و نسبت دو گسیل خودبخودی بر رفتار درجه درهمتنیدگی سیستم بررسی شده اشت.با تغییر هر یک از این پارامترها، در...
15 صفحه اولAlkaline-earth-metal atoms as few-qubit quantum registers.
We propose and analyze a novel approach to quantum information processing, in which multiple qubits can be encoded and manipulated using electronic and nuclear degrees of freedom associated with individual alkaline-earth-metal atoms trapped in an optical lattice. Specifically, we describe how the qubits within each register can be individually manipulated and measured with subwavelength optical...
متن کاملSemiempirical calculation of van der Waals coefficients for alkali-metal and alkaline-earth-metal atoms
The van der Waals coefficients, C6 , C8, and C10 for the alkali-metal ~Li, Na, K, and Rb! and alkaline-earthmetal ~Be, Mg, Ca, and Sr! atoms are estimated by a combination of ab initio and semiempirical methods. Polarizabilities and atom-wall coefficients are given as a diagnostic check, and the lowest order nonadiabatic dispersion coefficient, D8 and the three-body coefficient, C9 are also pre...
