Scientists from the University of Chicago found the first experimental evidence of “quantum superchemistry,” a phenomenon in which particles in the same quantum state undergo collective and accelerated chemical reactions. Cooling cesium atoms into a shared quantum state allows them to react collectively rather than through independent collisions, leading to faster reaction rates. The molecules resulting from these collisions also share the same quantum state, offering new control over reaction outcomes. The discovery represents a significant step toward understanding quantum-enhanced chemical reactions and could have implications for quantum chemistry, computing, and engineering, as well as fundamental physics research. |

A novel method for building large-scale quantum networks, proposed by UChicago researchers, could transform quantum computing and communication technologies. Classical computer networks and current approaches under study can’t effectively send quantum bits, or qubits, because of information loss and the inability to maintain the quantum properties. |
|
| |
|
|
|
| |
The new approach would use vacuum-sealed tubes equipped with spaced-out lenses to transport photons of light encoding quantum data across thousands of kilometers. With the potential to transmit 10 trillion qubits per second, the proposed network could revolutionize cybersecurity, data processing, and quantum computing and sensing technologies. |
