Optimal quantum control of multi-mode couplings between trapped ion qubits for scalable entanglement
T. Choi, S. Debnath, T. A. Manning +4
We demonstrate high fidelity entangling quantum gates within a chain of five trapped ion qubits by optimally shaping optical fields that couple to multiple collective modes of moti…
Beat note stabilization of mode-locked lasers for quantum information processing
R. Islam, W. C. Campbell, T. Choi +18
We stabilize a chosen radiofrequency beat note between two optical fields derived from the same mode-locked laser pulse train, in order to coherently manipulate quantum information…
Photon collection from a trapped ion--cavity system
J. D. Sterk, L. Luo, T. A. Manning +2
We present the design and implementation of a trapped ion cavity QED system. A single ytterbium ion is confined by a micron-scale ion trap inside a 2 mm optical cavity. The ion is…
Random Numbers Certified by Bell's Theorem
S. Pironio, A. Acin, S. Massar +8
Randomness is a fundamental feature in nature and a valuable resource for applications ranging from cryptography and gambling to numerical simulation of physical and biological sys…
Protocols and Techniques for a Scalable Atom--Photon Quantum Network
L. Luo, D. Hayes, T. A. Manning +5
Quantum networks based on atomic qubits and scattered photons provide a promising way to build a large-scale quantum information processor. We review quantum protocols for generati…
