• Title: Embedded structure in quantum theory, functional operator and multiverse
• Authors: Yoshiharu Kawamura,
• Abstract summary: We explore a wider theoretical framework that has quantum field theory built-in, taking the fact that quantum mechanics is reconstructed from quantum field theory as a hint. We formulate a quantum theory with an embedded structure by introducing functional operators, and we find that it could describe the level II multiverse.

• Abstract: We explore a wider theoretical framework that has quantum field theory built-in, taking the fact that quantum mechanics is reconstructed from quantum field theory as a hint. We formulate a quantum theory with an embedded structure by introducing functional operators, and we find that it could describe the level II multiverse. Topics related to a beginning of the universe such as inflation, the third quantization and the landscape are discussed in our formulation.

  We develop a general integration theory for operator-valued functions (quantum fields) with respect to positive operator-valued measures (quantum frames) A form of indefinitetemporality arises from quantum states in the context of relational frame bundles. This offers novel perspectives on the problem of reconciling principles of generally relativistic and quantum physics.

  We show that the recently proposed experience-centric quantum theory (ECQT) is a larger and richer theory of quantum behaviors. ECQT allows the quantum information of the closed quantum system's developed state history to continually contribute to defining manybody interactions. The interplay of unitarity and non-Markovianity in ECQT brings about a host of diverse behavioral phases.

  We explore the applicability of quantum-data learning to practical problems in high-energy physics. We make use of ansatz based on quantum convolutional neural networks and numerically show that it is capable of recognizing quantum phases of ground states. The observation of non-trivial learning properties demonstrated in these benchmarks will motivate further exploration of the quantum-data learning architecture in high-energy physics.
