Title: Hardy-like Quantum Pigeonhole Paradox and the Projected-Coloring Graph State
Authors: Weidong Tang
Abstract summary: A Hardy-like version of the quantum pigeonhole paradox is proposed, which can also be considered as a special kind of Hardy's paradox. Some Hardy-like quantum pigeonhole paradoxes can even set a new record for the success of demonstrating Bell nonlocality.

Abstract: A Hardy-like version of the quantum pigeonhole paradox is proposed, which can also be considered as a special kind of Hardy's paradox. Besides an example induced from the minimal system, a general construction of this paradox from an $n$-qubit quantum state is also discussed. Moreover, by introducing the projected-coloring graph and the projected-coloring graph state, a pictorial representation of the Hardy-like quantum pigeonhole paradox can be presented. This Hardy-like version of quantum pigeonhole paradox can be implemented more directly in the experiment than the original one, since it does not require some sophisticated techniques such as weak measurements. In addition, from the angle of Hardy's paradox, some Hardy-like quantum pigeonhole paradoxes can even set a new record for the success probability of demonstrating Bell nonlocality.

Generalized Einstein-Podolsky-Rosen Steering Paradox [18.5699135339787]
We present a generalized EPR steering paradox, which predicts a contradictory equality $2_Q=left( 1+deltaright)_C$. We test the paradox through a two-setting steering protocol, and find that the state is steerable if some specific measurement requirements are satisfied. Our construction also enlightens the building of EPR steering inequality, which may contribute to some schemes for typical quantum teleportation and quantum key distributions.

Hardy-type paradoxes for an arbitrary symmetric bipartite Bell scenario [0.0]
We give two generalizations of Hardy's arguments for manifesting such a paradox to an arbitrary, but symmetric Bell scenario. One can be naturally interpreted as a demonstration of the failure of transitivity of implications. A special case of which is equivalent to a ladder-proof-type argument for Hardy's paradox.

Quantum Discord Witness with Uncharacterized Devices [18.751513188036334]
We propose a new approach using uncharacterized measurements to witness quantum discord of an unknown bipartite state within arbitrary dimension system. The feature of high robustness against device imperfections, such as loss-tolerance and error-tolerance, shows our method is experimentally feasible.

Realigned Hardy's Paradox [18.40864487417613]
Hardy's paradox certifies that quantum mechanics cannot be completely described by local realistic theory. We propose a realigned Hardy's paradox to overcome this problem. One can anticipate that the realigned Hardy's paradox can tolerate more experimental imperfections.

Experimental demonstration of optimal unambiguous two-out-of-four quantum state elimination [52.77024349608834]
A core principle of quantum theory is that non-orthogonal quantum states cannot be perfectly distinguished with single-shot measurements. Here we implement a quantum state elimination measurement which unambiguously rules out two of four pure, non-orthogonal quantum states.
