چکیده

We present the first demonstration of a CNOT gate between two individually addressed neutral atoms. Our implementation of the CNOT uses Rydberg blockade interactions between neutral atoms held in optical traps separated by >8 microm. Using two different gate protocols we measure CNOT fidelities of F=0.73 and 0.72 based on truth table probabilities. The gate was used to generate Bell states with fidelity F=0.48+/-0.06. After correcting for atom loss we obtain an a posteriori entanglement fidelity of F=0.58.

Deterministic entanglement of two neutral atoms via Rydberg blockade

We demonstrate the deterministic entanglement of two individually addressed neutral atoms using a Rydberg blockade mediated controlled-NOT gate. Parity oscillation measurements reveal a Bell state fidelity of F = 0.58 ± 0.04, which is above the entanglement threshold of F = 0.5, without any correction for atom loss, and F = 0.71 ± 0.05 after correcting for background collisional losses. The fid...

Demonstration of a fundamental quantum logic gate.

We demonstrate the operation of a two-bit "controlled-NOT" quantum logic gate, which, in conjunction with simple single-bit operations, forms a universal quantum logic gate for quantum computation. The two quantum bits are stored in the internal and external degrees of freedom of a single trapped atom, which is first laser cooled to the zero-point energy. Decoherence effects are identified for ...

Rydberg-blockade controlled-NOT gate and entanglement in a two-dimensional array of neutral-atom qubits

We present experimental results on two-qubit Rydberg-blockade quantum gates and entanglement in a twodimensional qubit array. Without postselection against atom loss we achieve a Bell state fidelity of 0.73 ± 0.05. The experiments are performed in an array of single Cs atom qubits with a site to site spacing of 3.8 μm. Using the standard protocol for a Rydberg-blockade CZ gate together with sin...

Robust quantum gates on neutral atoms with cavity-assisted photon scattering

We propose a scheme to achieve quantum computation with neutral atoms whose interactions are catalyzed by single photons. Conditional quantum gates, including an N-atom Toffoli gate and nonlocal gates on remote atoms, are obtained through cavity-assisted photon scattering in a manner that is robust to random variation in the atom-photon coupling rate and which does not require localization in t...

Quantum Information Processing in Optical Lattices and Magnetic Microtraps

We review our experiments on quantum information processing with neutral atoms in optical lattices and magnetic microtraps. Atoms in an optical lattice in the Mott insulator regime serve as a large qubit register. A spindependent lattice is used to split and delocalize the atomic wave functions in a controlled and coherent way over a defined number of lattice sites. This is used to experimental...
