Spin Isomers of Hydrogen Molecules as a Potential Two-Level System for Encoding Quantum Information
Vyacheslav Voloshyn, Oleg Klenin
Introduction. In modern information theory, the idea of a fundamental connection between information, quantum mechanics and thermodynamics is becoming increasingly important. After the works of R. Landauer, the principle was formulated, which became the basis of a new field — information thermodynamics. On the other hand, the search for new ways of physical realization of qubits remains an urgent scientific problem. One of the potential quantum systems that has a natural two-state structure is the ortho- and para-states of the hydrogen molecule. The purpose. Hypothetical identification of the physical essence of the quantum-mechanical nature of information in the ortho/pair conversion of a hydrogen molecule, from the point of view of statistical mechanics and Landauer's thermodynamic principle as a fundamental energy limit for the legalization of information qubits. Results. From the point of view of quantum informatics, ortho/pair hydrogen molecules as quantum spin isomers can behave as different quantum components, because they have different statistical entropy. Therefore, they can be interpreted as two information configurations of one quantum system. Such a system is informationally and thermodynamically ordered in accordance with the Landauer principle and mathematically corresponding to the structure of a qubit or a logical two-level subsystem, isolated from the full four-dimensional Hilbert space of the two spins. The mathematical structure of this system corresponds to a two-level information space, which allows it to be interpreted as a potential model of an elementary quantum information carrier. Due to its antisymmetric structure, it shows increased adaptation in accordance with certain types of magnetic fluctuations, ions, chemical interactions and collective perturbations. The effective use of spin isomers as information carriers requires controlled quantum media, the creation of cryogenic and magnetic influences or isolated systems, and the synchronization of information operations with characteristic coherence times. Conclusions. The proposed conceptual and quantum-information analysis allows us to formulate a consistently consistent system of assumptions regarding a possible hypothesis about the interpretation of spin isomers of hydrogen as potential natural carriers of artificial quantum information. The practical implementation of this concept on the example of hydrogen requires further theoretical and experimental research aimed at studying the mechanisms of coordinated coherence, control of ortho/para-conversion and the possibilities of controlling the spin states of molecular systems.
