Approximating the quantum value of tilted XOR games to constant precision is RE-complete, implying binary nonlocal games are RE-hard to approximate.
A decomposition of Hilbert space into invariant subspaces for two orthogonal projections yields finite-dimensional approximations and explicit bounds on the spectral radius of [P,Q] that are tight in the constant-angle one-shifted case.
Ultralow-loss Si3N4 PICs generate path-encoded EPR pairs (F=0.9875) and fuse them into four-photon GHZ states at F=0.943(8) and 27 Hz—two orders of magnitude above prior silicon-photonic rates.
Subleading soft-gluon recoil rotates the heavy-quark spin-correlation plane; tracing over unresolved radiation dephases in-plane coherences while protecting the normal-axis correlation.
A hardware-native error model and loss-disciplined protocol for DI-QKD on Majorana processors is proposed with an EAT security proof, but secure distances are strictly bounded by poisoning-induced visibility collapse during photonic round-trips.
Quantum mechanics violates a causal inequality derived from absoluteness of observed events plus axiological time symmetry and no retrocausality in timelike scenarios, even under a weakened operational version of absoluteness.
A method strengthens Mermin-Klyshko-Bell inequalities beyond local bounds for entanglement detection in multipartite systems using coarsely calibrated measurements and derives trade-offs for separable versus general states.
Optimal bounds on multipartite nonlocality for threshold games are derived via a reduction to biased bipartite nonlocality in the LOCCG model.
Toponium strengthens the spin-singlet component in top-quark pairs, substantially enhancing entanglement and enabling observable quantum steering at 10 sigma and Bell nonlocality at 9 sigma near threshold with current LHC data.
Reports experimental generation of remote Bell entanglement between two giant atoms with fidelity 0.89 using driven-dissipative stabilization and in-situ frequency tuning.
Three authors each propose a resolution to Bell's theorem by dropping counterfactual definiteness, with one linking CHSH violation strength to spatial dimensions.
New combinatorial proofs and circuit designs for quantum error correction reduce physical qubit overhead by up to 10x and time overhead by 2-6x for codes including Steane, Golay, and surface codes.
In the massive Majorana field in 1+1 dimensions, the vacuum Bell-CHSH correlator is reduced to a single spectral weight, with the Tsirelson bound approached as the weight concentrates near modular eigenvalue 1.
A numerical optimization framework establishes lower bounds on quantum discord for specific Bell violations across six expressions under white noise and identifies two classes of optimized states.
Depolarizing channels suppress the correlations needed to witness both state-dependent and state-independent contextuality in sequential KCBS and Peres-Mermin implementations, leading to classicalization.
Synchronization subspaces (kernels of K = T_A ⊗ I - I ⊗ T_B) in finite-dimensional tensor-product Hilbert spaces obey a sharp linear-in-time drift bound under ε-compatible dynamics and coincide with diagonal isotypic components under finite group symmetry, with preserving dynamics characterized as a
Free massless Majorana fields in 1+1D with modular wedge localization nearly saturate the Tsirelson bound for the Bell-CHSH inequality.
Vertex operators of a chiral boson realize dichotomic bounded Hermitian operators that saturate the Tsirelson bound of the Bell-CHSH inequality in the vacuum.
Monte Carlo feasibility study at STCF finds reconstructed concurrence of 0.279 ± 0.007 for τ⁺τ⁻ pairs in the ππ channel using quantum tomography.
Kochen-Specker contextuality generalizes nonclassicality while Spekkens' noncontextuality generalizes classicality, reconciling the two as successive stages in a hierarchy of classicality.
A review of how quantum information science is expected to provide new tools and insights for nuclear and high-energy physics phenomenology and quantum simulations.
Bell's inequality is claimed not to refute local reality because, in the Heisenberg picture, each subsystem has a local descriptor and CHSH correlations emerge only when histories meet.
