Macroscopic Quantum State Analyzed Particle by Particle
(ACS Publications, 2015-03-27)
Article.
Accés obert
Article.
Accés obert
Macroscopic quantum phenomena, e.g., superconductivity and squeezing, are believed to result from
entanglement of macroscopic numbers of particles. We report the first direct study of this kind of
entanglement: we use ...
Long-term laser frequency stabilization using fiber interferometers
(AIP, 2015-07-09)
Article.
Accés obert
Article.
Accés obert
We report long-term laser frequency stabilization using only the target laser and a pair of 5 m fiber interferometers, one as a frequency reference and the second as a sensitive thermometer to stabilize the frequency ...
Passive Decoy-State Quantum Key Distribution with Coherent Light
(MDPI, 2015-06-12)
Article.
Accés obert
Article.
Accés obert
Signal state preparation in quantum key distribution schemes can be realized using either an active or a passive source. Passive sources might be valuable in some scenarios; for instance, in those experimental setups ...
Strong experimental guarantees in ultrafast quantum random number generation
(American Physical Society, 2015-01-12)
Article.
Accés obert
Article.
Accés obert
We describe a methodology and standard of proof for experimental claims of quantum random-number
generation (QRNG), analogous to well-established methods from precision measurement. For appropriately
constructed physical ...
Loophole-free Bell inequality violation using electron spins separated by 1.3 kilometres

More than 50 years ago1, John Bell proved that no theory of nature that obeys locality and realism2 can reproduce all the predictions of quantum theory: in any local-realist theory, the correlations between outcomes of ...
