Harvard scientists trap ultra-cold molecules for quantum computing breakthroughs

Harvard scientists have successfully trapped ultra-cold polar molecules to perform quantum operations, marking a first in quantum computing. This breakthrough allows for the use of complex molecular structures as qubits, which could enhance the speed of quantum technology. Previously, smaller particles were favored due to the challenges of using molecules, which were seen as too unpredictable. The team used optical tweezers to stabilize sodium-cesium molecules, enabling them to create a two-qubit Bell state with 94 percent accuracy. This development is a significant step toward building a molecular quantum computer. The researchers believe that the unique properties of molecules can lead to further advancements in quantum computing technology.
