Near-Perfect Simultaneous Measurement of a Qubit Register
M. Acton, K. -A. Brickman, P. C. Haljan +3
Simultaneous measurement of multiple qubits stored in hyperfine levels of trapped 111Cd+ ions is realized with an intensified charge-coupled device (CCD) imager. A general theory o…
Implementation of Grover's Quantum Search Algorithm in a Scalable System
K. -A. Brickman, P. C. Haljan, P. J. Lee +3
We report the implementation of Grover's quantum search algorithm in the scalable system of trapped atomic ion quantum bits. Any one of four possible states of a two-qubit memory i…
Entanglement of Trapped-Ion Clock States
P. C. Haljan, P. J. Lee, K. -A. Brickman +3
A Mølmer-Sørensen entangling gate is realized for pairs of trapped Cd ions using magnetic-field insensitive "clock" states and an implementation offering reduced sensit…
Spin-dependent forces on trapped ions for phase-stable quantum gates and motional Schrodinger-cat states
P. C. Haljan, K. -A. Brickman, L. Deslauriers +2
Favored schemes for trapped-ion quantum logic gates use bichromatic laser fields to couple internal qubit states with external motion through a "spin-dependent force." We introduce…
Zero-Point cooling and low heating of trapped 111Cd+ ions
L. Deslauriers, P. C. Haljan, P. J. Lee +4
We report on ground state laser cooling of single 111Cd+ ions confined in radio-frequency (Paul) traps. Heating rates of trapped ion motion are measured for two different trapping…
Atomic Qubit Manipulations with an Electro-Optic Modulator
P. J. Lee, B. B. Blinov, K. Brickman +6
We report new techniques for driving high-fidelity stimulated Raman transitions in trapped ion qubits. An electro-optic modulator induces sidebands on an optical source, and interf…
