Heisenberg's uncertainty principle forms a fundamental element of quantum mechanics.
Uncertainty relations in terms of entropies were initially proposed to deal with conceptual …

Quantum repeaters hold promise for scalable long-distance quantum communication. The
basic building block is a quantum light–matter interface that generates non-classical …

By pulsed s-shell resonant excitation of a single quantum dot-micropillar system, we
generate long streams of 1000 near-transform-limited single photons with high mutual …

Neutrino oscillation is deemed as an interesting physical phenomenon and shows the
nonclassical features made apparently by the Leggett–Garg inequality. The uncertainty …

The uncertainty principle is a striking and fundamental feature in quantum mechanics,
distinguishing it from classical mechanics. It offers an important lower bound to predict …

The uncertainty principle, which demonstrates the intrinsic uncertainty of nature from an
information-theory perspective, is at the heart of quantum information theory. In the realm of …

We demonstrate high-fidelity, quantum nondemolition, single-shot readout of a
superconducting flux qubit in which the pointer state distributions can be resolved to below …

We describe a cheating strategy enabled by the features of massive open online courses
(MOOCs) and detectable by virtue of the sophisticated data systems that MOOCs provide …

Crosstalk is a leading source of failure in multiqubit quantum information processors. It can
arise from a wide range of disparate physical phenomena, and can introduce subtle …

The uncertainty principle is a fundamental principle in quantum physics. It implies that the
measurement outcomes of two incompatible observables cannot be predicted …
