Through a ring of fire: Information Preservation across Horizons
Abstract
Over the past decade it has become clear that spacetime has the capacity to both entangle qubits and to destroy the information that they carry. It is becoming clear that a subtle relationship exists between quantum entanglement, detector responses, and quantum fields, and the structure of spacetime. The goal of this proposal is to investigate this relationship by providing both a firm theoretical foundation for its description, and to see how the predictions that emerge from this foundation can be tested by experiment. Very little is presently known as to what happens when spacetime structures such as event horizons are present and so questions such as what happens to entangled qubits as they cross a spacetime horizon, and what becomes of their information processing power in the process will be explored. This questions will be addressed using research methods that my group has pioneered, in particular new mode summation techniques that reduce computational time by a large factor. The results of this project will shed new light on the famous information paradox in general relativity, and should be amenable to experimental test/simulation in laboratory settings.
