Quantum correlations between two parties are essential for the argument of Einstein,
Podolsky, and Rosen in favor of the incompleteness of quantum mechanics. Schrödinger …

Entanglement is an important resource for quantum technologies. There are many ways
quantum systems can be entangled, ranging from the two-qubit case to entanglement in …

Device-independent quantum key distribution (DIQKD) is the art of using untrusted devices
to distribute secret keys in an insecure network. It thus represents the ultimate form of …

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 …

We explore the different meanings of “quantum uncertainty” contained in Heisenberg's
seminal paper from 1927, and also some of the precise definitions that were developed …

We present a new quantum-memory-assisted entropic uncertainty relation for multipartite
systems which shows the uncertainty principle of quantum mechanics. Notably, our results …

For a pair of incompatible quantum measurements, the total uncertainty can be bounded by
a state-independent constant. However, such a bound can be violated if the quantum system …

Quantum measurements are inherently probabilistic and quantum theory often forbids
precisely predicting the outcomes of simultaneous measurements. This phenomenon is …

We approach the physical implications of the noncommutative nature of complementary
observable algebras (COAs) from an information theoretic perspective. In particular, we …

Employing the lattice theory on majorization, the universal quantum uncertainty relation for
any number of observables and general measurement is investigated. It is found that 1) the …
