Analysis of Coincidence-Time Loopholes in Experimental Bell Tests
B. G. Christensen, A. Hill, P. G. Kwiat +6
We apply a distance-based Bell-test analysis method [E. Knill et al., Phys. Rev. A. 91, 032105 (2015)] to three experimental data sets where conventional analyses failed or require…
Heisenberg's Introduction of the `Collapse of the Wavepacket' into Quantum Mechanics
R. Y. Chiao, P. G. Kwiat
Heisenberg in 1929 introduced the "collapse of the wavepacket" into quantum theory. We review here an experiment at Berkeley which demonstrated several aspects of this idea. In thi…
Exploring Hilbert Space: accurate characterisation of quantum information
A. G. White, D. F. V. James, W. J. Munro +1
We report the creation of a wide range of quantum states with controllable degrees of entanglement and entropy using an optical two-qubit source based on spontaneous parametric dow…
Maximizing the entanglement of two mixed qubits
W. J. Munro, D. F. V. James, A. G. White +1
Two-qubit states occupy a large and relatively unexplored Hilbert space. Such states can be succinctly characterized by their degree of entanglement and purity. In this letter we i…
Entangled state quantum cryptography: Eavesdropping on the Ekert protocol
D. S. Naik, C. G. Peterson, A. G. White +2
Using polarization-entangled photons from spontaneous parametric downconversion, we have implemented Ekert's quantum cryptography protocol. The near-perfect correlations of the pho…
Non-maximally entangled states: production, characterization and utilization
Andrew G. White, Daniel F. V. James, Philippe H. Eberhard +1
Using a spontaneous-downconversion photon source, we produce true non-maximally entangled states, i.e., without the need for post-selection. The degree and phase of entanglement ar…
