Hyper Entanglement: Atomic Vibrations Enable Superposition

Quantum Control: Caltech Physicists Improve Computing and Hyper Entanglement with Atomic Motion Caltech researchers under Professor Manuel Endres have improved quantum system control by using unwanted atomic motion to encode quantum information. An important experiment showed hyper-entanglement in large particles like neutral atoms.

It describes a new quantum information storage and manipulation technology that could improve simulation, quantum computing, and precision measurement. Professor Endres controls atoms with laser-powered optical tweezers. His team uses these tweezers to move atoms in arrays to study quantum systems. The regular jiggling motion of atoms has made these systems harder to govern, but the Caltech scientists cleverly reversed this. Disorder to Asset Co-lead author Adam Shaw (PhD ’24) says, “It demonstrates that atomic motion, which is generally regarded as a form of undesired noise in quantum systems, can be transformed into a strength.” Researchers encoded quantum information using this motion to solve a long-standing challenge. This approach required cooling optical tweezers' alkaline-earth neutral atom arrays. The team compares ‘erasure cooling’ to James Clerk Maxwell’s 1867 thought experiment in which a demon sorts and measures particles. Maxwell's demon Endres says it measures atom motion and performs an operation. This technology drove atoms to near-total stillness, outperforming the best laser cooling methods.

Hyper Entanglement Unlocked

After cooling, the scientists caused atoms to oscillate 100 nanometres. They excited the atoms into two oscillations to generate superposition. Superposition allows a particle to have opposite properties like an up-and-down spin. Endres compared an atom in superposition to a child on a swing pushed by two parents on opposite sides. They linked atoms' movements over several micrometres from this condition. This was revolutionary: they hyper-entangled these combinations. Due to normal entanglement, measuring one particle's characteristic immediately yields the other's characteristic, regardless of distance. For instance, if one particle's spin is up, the second may always be down. Further, hyper entanglement links two particle attributes. This is like twins who were born separated but had the same names and car models. At Caltech, the team highly entangled pairs of atoms to connect their internal energy levels, states of motion, and electrical states. We can encode more quantum information per atom. Resource scarcity increases entanglement. This experiment shows super entanglement in neutral atoms or ions for the first time. Photons showed it before. Building the Quantum Toolbox It boosts quantum control. Pushing atomic control limitations was the goal.Kind of like building a toolbox: It originally regulated an atom's electron motion and now controls its outer motion. Like a fully mastered toy atom. Conclusion Caltech physicists created hyper entanglement in atoms using novel cooling and control technologies. By carefully manipulating atom mobility with optical tweezers, they established entangled positions and intrinsic characteristics. This Science article highlights the potential of using atoms as building blocks for future quantum systems, which could improve quantum computing and related technologies.
