Demonstration of Minisuperspace Quantum Cosmology Using Quantum Computational Algorithms on IBM Quantum Computer
Introduction Quantum computers promise to efficiently solve important problems that are intractable on a conventional computer. In recent years, quantum computational algorithms have emerged as an exciting new way to explore quantum cosmology. Quantum cosmology is the study of the universe's dynamics without constructing a complete theory of quantum gravity. By leveraging the power of quantum computers, researchers are able to gain new insights into the behavior of the universe on a quantum level. Quantum Cosmology In quantum cosmology, the universal wavefunction exists in an infinite-dimensional superspace over all possible 3D metrics and modes of matter configurations. However, due to the complexity of these calculations, researchers often use a simplified approach known as minisuperspaces. Minisuperspaces constrain the degrees of freedom to particular 3D metrics and uniform scalar field configurations, making the problem more tractable while still providing valuable insights in...
