Evidencing Macroscopic Quantum Coherence using Confined Uniform Magnetic Field
Abstract
A previously unexplored scheme is devised for creating and certifying coherent quantum superposition of distinctly separated states of a spin-tagged massive object passing through a confined uniform magnetic field. This results in entangling the spatial and spin parts of a two-component Pauli wavefunction such that the entailed coherence can be conveniently certified by spin measurements alone. The implementability of this scheme is analysed using NV-centre nanodiamonds of masses ∼ 1010 amu based on the current technological capabilities.
