Six Quantum Hardware Protocols Testing Boundary Signatures of the ER=EPR Conjecture on IBM Marrakesh

Six quantum circuit experiments performed on ibmₘarrakesh (IBM Quantum, 156 qubits, Heron R2 architecture) are reported, designed to test boundary signatures of the ER=EPR conjecture within the AdS₂/JT gravity framework, with the Sachdev-Ye-Kitaev (SYK) model as the holographic dual of the black hole horizon. The experiments were executed iteratively: each result raised new questions that directly motivated the next protocol. In order of execution they implement: tripartite entanglement certification via the Mermin operator (|⟨M⟩| = 3. 885) ; a traversable wormhole baseline using a Bell-pair thermofield double (F (g=π/2) = 1. 000) ; black hole evaporation unitarity via the Hayden-Preskill protocol (Fᵣec = 0. 9983, with the decoder reduced to zero two-qubit gates by the compiler) ; a corrected traversable wormhole using genuine SYK scrambling and exact Majorana coupling (F (g=0) = 0. 020, F (g=π/2) = 0. 953, GJW gain = 0. 933) ; quantum chaos via out-of-time-order correlators (λL = 1. 975 ± 0. 294, 54. 8% of the Maldacena-Shenker-Stanford bound) ; and horizon growth under information absorption consistent with the Bekenstein area law. Total QPU time across all experiments: 7 minutes 2 seconds. All results are consistent with the boundary predictions of the ER=EPR framework. These experiments demonstrate that the relevant CFT information dynamics are reproducible on current NISQ hardware.
