Quantum gate teleportation between separated zones of a trapped-ion processor

Author(s)
Yong Wan, Daniel Kienzler, Stephen D. Erickson, Karl H. Mayer, Ting R. Tan, Jenny J. Wu, Hilma H. Macedo De Vasconcelos, Scott C. Glancy, Emanuel H. Knill, David J. Wineland, Andrew C. Wilson, Dietrich G. Leibfried
Large-scale quantum computers will inevitably require quantum gate operations between widely separated qubits, even within a single quantum information

Chained Bell inequality experiment with high-efficiency measurements

Author(s)
Ting Rei Tan, Stephen D. Erickson, Peter L. Bierhorst, Daniel Kienzler, Scott C. Glancy, Emanuel H. Knill, Dietrich G. Leibfried, David J. Wineland, Yong Wan
We report correlation measurements on two 9Be+ ions that violate a chained Bell inequality obeyed by any local-realistic theory. The correlations can be modeled

Preparation of entangled states through Hilbert space engineering

Author(s)
Yiheng Lin, John P. Gaebler, Florentin Reiter, Ting Rei Tan, Ryan S. Bowler, Yong Wan, Adam C. Keith, Emanuel H. Knill, Kevin J. Coakley, Dietrich G. Leibfried, David J. Wineland, Scott C. Glancy
Entangled states are a crucial resource for quantum-based technologies such as quantum computers and quantum communication systems. Exploring new methods for

High Fidelity Universal Gate Set for 9Be+ Ion Qubits

Author(s)
John P. Gaebler, Ting Rei Tan, Yong Wan, Yiheng Lin, Ryan S. Bowler, Adam C. Keith, Scott C. Glancy, Kevin J. Coakley, Emanuel H. Knill, Dietrich G. Leibfried, David J. Wineland
We report high-fidelity laser-beam-induced quantum logic gates on qubits comprised of hyperfine states in 9Be+ ions, achieved in part through a combination of

A strong loophole-free test of local realism

Author(s)
Lynden K. Shalm, Evan Meyer-Scott, B. G. Christensen, Peter L. Bierhorst, Michael A. Wayne, Deny Hamel, Martin J. Stevens, Thomas Gerrits, Scott C. Glancy, Michael S. Allman, Kevin J. Coakley, Shellee D. Dyer, Adriana E. Lita, Varun B. Verma, Joshua C. Bienfang, Alan L. Migdall, Yanbao Zhang, William Farr, Francesco Marsili, Matthew D. Shaw, Jeffrey Stern, Carlos Abellan, Waldimar Amaya, Valerio Pruneri, Thomas Jennewein, Morgan Mitchell, P. G. Kwiat, Richard P. Mirin, Emanuel H. Knill, Sae Woo Nam
We present a loophole-free violation of local realism using entangled photon pairs. We ensure that all relevant events in our Bell test are spacelike separated

Analysis of coincidence-time loopholes in experimental Bell tests

Author(s)
B. G. Christensen, A. Hill, P. G. Kwiat, Emanuel H. Knill, Sae Woo Nam, Kevin J. Coakley, Scott C. Glancy, Lynden K. Shalm, Y. Zhang
We apply a distance-based Bell-test analysis method ["Bell inequalities for continuously emitting sources" E. Knill et al. arXiv:14097732 (2014)] to three

Bell Inequalities for Continuously Emitting Sources

Author(s)
Emanuel H. Knill, Scott C. Glancy, Sae Woo Nam, Kevin J. Coakley, Yanbao Zhang
A common experimental strategy for demonstrating non-classical correlations is to show violation of a Bell inequality by measuring a continuously emitted stream

Generation and characterization of high-purity, pulsed squeezed light at telecom wavelengths from pp-KTP

Author(s)
Thomas Gerrits, Martin J. Stevens, Burm Baek, Brice R. Calkins, Adriana E. Lita, Scott C. Glancy, Emanuel H. Knill, Sae Woo Nam, Richard P. Mirin, Robert Hadfield, Ryan Bennink, Warren Grice, Sander N. Dorenbos, Tony Zijlstra, Teun Klapwijk, Val Zwiller
We characterize a pp-KTP crystal designed to produce pure single mode squeezed vacuum at 1570 nm. Measurements show a raw (corrected) Hong-Ou-Mandel
