• Abstract: We introduce an operational, boundary-first framework that embeds relativistic quantum-information protocols into anti-de Sitter/Conformal Field Theory (AdS/CFT) by coupling an Unruh--DeWitt detector directly to a local scalar primary operator of a holographic CFT. Using the universal CFT Wightman function, we compute the detector's reduced density operator perturbatively, retaining both excitation probabilities and coherences. As a concrete resource-theoretic application, we implement magic resource (mana) harvesting with a qutrit probe. For a CFT dual to global AdS, we show that the harvested mana sharply distinguishes the two admissible scalar quantizations in the Breitenlohner--Freedman window, with the standard quantization yielding systematically larger mana than the alternate one. Our results provide a viable way of testing holography principle through quantum information resource.

  A proof of quantumness is an efficiently verifiable interactive test that an efficient quantum computer can pass. Existing single-round protocols require large quantum circuits, whereas multi-round ones use smaller circuits but require experimentally challenging mid-circuit measurements. We construct efficient single-round proofs of quantumness based on existing knowledge assumptions.

  We reformulate the technique of third quantization in a way that explicitly connects all three methods. We first show that our formulation reveals a fundamental dissipative symmetry present in all quadratic bosonic or fermionic Lindbladians. For bosons, we then show that the Wigner function and the characteristic function can be thought of as ''wavefunctions'' of the density matrix.
