Cascading amplifiers can create exponentially large coherence
Lucas A. Ostrowski, Giacomo Pantaleoni, Howard M. Wiseman +1
A standard laser beam has photon degeneracy, or coherence, , of at most , where is the number of photons in the laser itself. Even quantum-engineered lase…
Detection-loophole-free nonlocality in the simplest scenario
Nandana T Raveendranath, Travis J. Baker, Emanuele Polino +7
Loophole-free quantum nonlocality often demands experiments with high complexity (defined by all parties' settings and outcomes) and multiple efficient detectors. Here, we identify…
Analytical results for laser models producing a beam with sub-Poissonian photon statistics and coherence scaling as the Heisenberg limit
Lucas A. Ostrowski, Travis J. Baker, Dominic W. Berry +1
Recent advances in laser theory have demonstrated that a quantum enhancement is possible for the production of coherence by a continuous-wave laser device. Curiously…
Properties and Applications of Partially Deterministic Polytopes
Marwan Haddara, Howard M. Wiseman, Eric G. Cavalcanti
The assumption of a deterministic local hidden variable model constrains the experimentally accessible statistics in a Bell experiment to be contained in the Bell-local polytope. B…
Quantum Assemblage Tomography
Luis Villegas-Aguilar, Yuanlong Wang, Alex Pepper +7
A central requirement in asymmetric quantum nonlocality protocols, such as quantum steering, is the precise reconstruction of state assemblages -- statistical ensembles of quantum…
