Atoms are coerced into a quantum state of 'intensive entanglement' through precision manipulation with tweezers constructed from laser light by scientists in this study.
Researchers at Caltech have developed a groundbreaking method to manipulate individual atoms and create a state of hyper-entanglement, which could revolutionize quantum computing and quantum simulations. This advancement, published in the journal Science, overcomes a persistent issue in the process by harnessing the natural motion of atoms to create hyper-entangled sets.
Adam Shaw, a postdoctoral researcher and first author of the study, stated that atomic motion—normally a source of unwanted noise—has been transformed into a strength in this breakthrough. By linking both the states of motion and electronic states of a pair of atoms, the team was able to create hyper-entangled sets that can share multiple properties simultaneously.
Hyper-entanglement, distinct from traditional quantum entanglement, was achieved by first cooling an alkaline earth atom and almost completely freezing its motion through a novel method, followed by oscillating the atoms like a pendulum in two directions simultaneously, and finally entangling them with partners that mirrored their motion and electronic states.
This achievement paves the way for increased information density in quantum systems, encoding more quantum information per atom. According to co-lead author Manuel Endres, a professor of physics at Caltech, it allows for more entanglement with fewerresources. This discovery appears to be a critical step in terms of both volume and efficiency, opening new possibilities for quantum technology applications such as computing, simulation, and precision measurements.
The team's experiment aimed to determine the limits of control they could exercise over the atoms, mastering the atom like a toy. Potential applications include enhanced quantum computing, complex system modeling through quantum simulations, improved secure quantum communication, and advanced metrology for high-precision measurements. Hyper-entanglement offers new pathways for information encoding and manipulation, potentially accelerating the development of future quantum technologies.
