Addressing the Conflict Between Quantum Mechanics and General Relativity

Leonard Susskind and colleagues introduced four postulates alongside the principle of black hole complementarity to address the black hole information paradox. However, a group of researchers, now known collectively by the acronym AMPS (after their initials), demonstrated that these principles are mutually inconsistent, culminating in what is now referred to as the firewall paradox. Subsequently, the advent of the AdS/CFT correspondence marked a paradigm shift, challenging the notion of information loss in black hole processes. This duality posited that information is preserved and encoded within the quantum state of a conformal field theory (CFT) residing on the boundary of the Anti-de Sitter (AdS) space. Efforts in the field redirected their focus toward resolving the firewall paradox, emphasizing the decoding of Hawking radiation. These investigations increasingly incorporated insights from quantum computation, bridging the disciplines of quantum gravity and quantum information theory. This approach contrasts sharply with Albert Einstein’s methodology in his quest for a unified field theory. Rooted in his realist worldview, Einstein’s pursuit under the framework of general relativity epitomized a classical and deterministic approach to physics, distinct from the paradigm emerging in modern quantum gravity research. A groundbreaking experimental proposal, termed "quantum gravity in the lab," sought to leverage the Sycamore quantum chip for a novel experiment probing the possibility of teleportation through a holographic wormhole. This chapter concludes with an analysis of this experiment and its profound philosophical implications.
