• Abstract: We address nonclassicality of hybrid coherent states (HCS), i.e. states expressed as superpositions of coherent states and single-photon-added coherent (SPAC) state. In particular, we evaluate their photon statistics, squeezing, and negativity of the Wigner function. Our results indicated that HCS may exhibit larger nonclassicalities than SPAC state. We also suggest a generation scheme for HCS which involves Kerr nonlinearity and postselection.

  Contextuality and nonlocality are distinct manifestations at the foundation of quantum mechanics, yet their coexistence within a single quantum state remains subtle.<n>We show that contextuality is governed solely by a population parameter $pangle$, associated with the occupation of the qutrit subsystem in the $|2rangle level.<n>In contrast, nonlocality depends irreducibly on coherence, involving both amplitudes and phases encoded in parameters $(X_i, Y_i)$.

  We propose two schemes for generating Wigner-negative entangled states unconditionally in mechanical resonators. We show analytically that both schemes stabilize a Wigner-negative entangled state that combines the entanglement of a two-mode squeezed vacuum with a cubic nonlinearity. We then perform extensive numerical simulations to test the robustness of Wigner-negative entanglement attained by approximate CPE states stabilized in the presence of thermal decoherence.

We show that the concurrence of a pure state in any high-dimensional multipartite system can be equivalently represented by these overlaps.
