Colloquium: Quantum coherence as a resource
The coherent superposition of states, in combination with the quantization of observables,
represents one of the most fundamental features that mark the departure of quantum …

Quantum entanglement
All our former experience with application of quantum theory seems to say that what is
predicted by quantum formalism must occur in the laboratory. But the essence of quantum …

Group-invariant quantum machine learning
Quantum machine learning (QML) models are aimed at learning from data encoded in
quantum states. Recently, it has been shown that models with little to no inductive biases (ie …

The classical-quantum boundary for correlations:<? format?> Discord and related measures
One of the best signatures of nonclassicality in a quantum system is the existence of
correlations that have no classical counterpart. Different methods for quantifying the …

Necessary and sufficient condition for nonzero quantum discord
Quantum discord characterizes “nonclassicality” of correlations in quantum mechanics. It
has been proposed as the key resource present in certain quantum communication tasks …

Quantum discord for two-qubit states
Quantum discord, a kind of quantum correlation, is defined as the difference between
quantum mutual information and classical correlation in a bipartite system. In general, this …

Experimental quantum computing without entanglement
Deterministic quantum computation with one pure qubit (DQC1) is an efficient model of
computation that uses highly mixed states. Unlike pure-state models, its power is not derived …
