This paper explores the potential of quantum self-adaptive spacetime geometry – a novel computational framework leveraging quantum entanglement to dynamically adjust spacetime parameters and enable precise spacetime modeling. Traditional approaches to spacetime simulation rely on manually designed geometries, limiting their adaptability. We propose a mechanism that dynamically adjusts spacetime geometry based on learned data and environmental information, automating the process through a specialized spacetime geometry calculation algorithm. The core claim is that this framework offers a significant advancement in spacetime simulation, enabling more accurate and flexible modeling compared to conventional methods. This work introduces a dynamic spacetime geometry parameter adjustment system, demonstrating its potential for enhanced simulation fidelity and computational efficiency.
This paper discusses how the transactional interpretation of quantum mechanics can provide for a natural account of the emergence of spacetime events from a quantum substratum. In this account, spacetime is not a substantive manifold that becomes occupied with events; rather, spacetime itself exists only in virtue of specific actualized events. This implies that spacetime is discrete rather than continuous, and that properties attributed to spacetime based on the notion of a continuum are idealizations that do not apply to the real physical world. It is further noted that the transactional picture of the emergence of spacetime can provide the quantum dynamics that underlie the causal set approach as proposed by Sorkin and others.
In 1-out-of-2 oblivious transfer (OT), Alice inputs numbers
x0,x1, Bob inputs a bit
b and outputs
xb. Secure OT requires that Alice and Bob learn nothing about
b and
xb, respectively. We define spacetime-constrained oblivious transfer (SCOT) as OT in Minkowski spacetime in which Bob must output
xb within
Rb, where
R0 and
R1 are fixed spacelike separated spacetime regions. We show that unconditionally secure SCOT is impossible with classical protocols in Minkowski (or Galilean) spacetime, or with quantum protocols in Galilean spacetime. We describe a quantum SCOT protocol in Minkowski spacetime, and we show it unconditionally secure.
