rydberg blockade controlled not gate and entanglement in a two dimensional Array of neutral atom qubits
Physical Review A, 2015Co-Authors: Kara Maller, L Isenhower, Martin Lichtman, Tian Xia, Yuan Sun, M J Piotrowicz, Alex Carr, M SaffmanAbstract:We present experimental results on two-qubit Rydberg-blockade quantum gates and entanglement in a Two-Dimensional qubit Array. Without postselection against atom loss we achieve a Bell state fidelity of $0.73\ifmmode\pm\else\textpm\fi{}0.05$. The experiments are performed in an Array of single Cs atom qubits with a site to site spacing of $3.8\phantom{\rule{0.28em}{0ex}}\ensuremath{\mu}\mathrm{m}$. Using the standard protocol for a Rydberg-blockade ${C}_{Z}$ gate together with single qubit operations we create Bell states and measure their fidelity using parity oscillations. We analyze the role of ac Stark shifts that occur when using two-photon Rydberg excitation and show how to tune experimental conditions for optimal gate fidelity.

Without post selection against atom loss we achieve a Bell state fidelity of $0.73\pm 0.05$, the highest value reported to date. The experiments are performed in an Array of single Cs atom qubits with a site to site spacing of $3.8 ~ \mu\rm m$.

label free protein recognition two dimensional Array using nanomechanical sensors
Nano Letters, 2008Co-Authors: Min Yue, Jeanne C Stachowiak, Henry Lin, Ram H Datar, Richard J Cote, Arun MajumdarAbstract:We demonstrate Two-Dimensional multiplexed real-time, label-free antibody−antigen binding assays by optically detecting nanoscale motions of Two-Dimensional Arrays of microcantilever beams. Prostate specific antigen (PSA) was assayed using antibodies covalently bound to one surface of the cantilevers by two different surface chemistries, while the nonreaction surfaces were passivated by poly(ethylene glycol)-silane. PSA as low as 1 ng/mL was detected while 2 mg/μl of bovine serum albumin induced only negligible deflection on the cantilevers.

Continuous surface-relief gratings for Two-Dimensional Array generation
Optical Computing, 1993Co-Authors: P. Ehbets, Hans Peter Herzig, D. Prongue, Michael T. GaleAbstract:Continuous surface-relief phase gratings for Two-Dimensional (2-D) Array generation have been designed and fabricated by laser-beam writing lithography. Separable and non-separable solutions for the design of 2-D fan-out elements are compared. A 9 X 9 fan-out element has been fabricated in photoresist by laser-beam writing. A diffraction efficiency of 94% and an uniformity better than +/- 8% over the whole Array were achieved.

High-efficiency continuous surface-relief gratings for Two-Dimensional Array generation.
Optics letters, 1992Co-Authors: P. Ehbets, Hans Peter Herzig, D. Prongue, Michael T. GaleAbstract:Continuous surface-relief phase gratings for Two-Dimensional (2-D) Array generation have been realized by laser-beam writing lithography. For a 9 × 9 fan-out element, a diffraction efficiency of 94% and a uniformity of better than ±8% have been achieved. These are, to our knowledge, the best published results for 2-D surface-relief fan-out elements. Separable and nonseparable solutions for the design of 2-D fan-out elements are discussed.
