Physical theories constrained with local quantum structure and satisfying the no-signalling principle can allow beyond-quantum global states. In a standard Bell experiment, correlations obtained from any such beyond-quantum bipartite state can always be reproduced by quantum states and measurements, suggesting local quantum structure and no-signalling to be the axioms to isolate quantum correlations. In this letter, however, we show that if the Bell experiment is generalized to allow local…

Local quantum measurement and no-signaling imply quantum correlations.

We show that, assuming that quantum mechanics holds locally, the finite speed of information is the principle that limits all possible correlations between distant parties to be quantum mechanical as

Limited preparation contextuality in quantum theory and its relation to the Cirel'son bound

The Kochen--Specker (KS) theorem lies at the heart of the foundations of quantum mechanics. It establishes the impossibility of explaining predictions of quantum theory by any noncontextual

Local orthogonality as a multipartite principle for quantum correlations

Local orthogonality, an intrinsically multipartite principle stating that events involving different outcomes of the same local measurement must be exclusive or orthogonal, is introduced and it is proved that it is equivalent to no-signalling in the bipartite scenario but more restrictive for more than two parties.

Deriving quantum theory from its local structure and reversibility.

In the particular case in which the local systems are identical qubits, it is shown that any theory admitting at least one continuous reversible interaction must be identical to quantum theory.

Composition of Multipartite Quantum Systems: Perspective from Timelike Paradigm.

Figuring out the physical rationale behind natural selection of quantum theory is one of the most acclaimed quests in quantum foundational research. This pursuit has inspired several axiomatic

The Uncertainty Principle Determines the Nonlocality of Quantum Mechanics

Two central concepts of quantum mechanics, Heisenberg’s uncertainty principle and a subtle form of nonlocality that Einstein famously called “spooky action at a distance,” are shown to be linked.

Typical local measurements in generalized probabilistic theories: emergence of quantum bipartite correlations.

It is found that if only a subset of typical local measurements can be made then all the bipartite correlations produced in a GPT can be simulated to a high degree of accuracy by quantum mechanics.

Unified framework for correlations in terms of local quantum observables.

If the theory is such that all local quantum measurements are possible, one obtains the correlations corresponding to the extension of Gleason's Theorem to multipartite systems, and it is proved the existence of a gap for three or more parties.

Measurement-Device-Independent Verification of Quantum Channels.

This work experimentally demonstrates a measurement-device-independent protocol for certifying that an unknown channel acts as an entanglement-preserving channel, and shows that, even under realistic experimental conditions, the present verification protocol is still capable of affirming the quantum behavior in a faithful manner with minimal trust on the measurement device.

All entangled quantum states are nonlocal.

It is shown that, as a consequence of this result, such a class of nonlocal games is able to witness quantum entanglement, however weak, and reveal nonlocality in any entangled quantum state.
