Entangled quantum bits per second (ebps) indicates a quantum network’s throughput. In this study, researchers collected ebps measurements over a suite of fiber connections on a quantum network testbed. They then compared these measurements with capacity estimates for a conventional fiber-optic network at a range of distances. The study finds that ebps throughput decays sharply with distance in ways that differ from conventional networks.

For the first time, scientists can distinguish the proportion of bromoform molecules that directly break bonds (dissociate) vs. those that rearrange (isomerize). This is an important step toward understanding the formation of bromoform isomers, which had long been predicted but had not been fully experimentally confirmed.

The trace anomaly is one of the quantities that encodes the energy and momentum of particles built from quarks. Scientists believe the trace anomaly is crucial for keeping quarks bonded in subatomic particles. In this study, scientists calculated the trace anomaly for nucleons and pions. The calculations show that in the pion, the mass distribution is similar to the charge distribution of the neutron and in the nucleon, the mass distribution is similar to the charge distribution of the proton.

The behavior of catalysts that promote chemical reactions is not always straightforward. Using a combination of experiments and computer simulations, scientists now understand how oxygen affects the way the catalyst copper oxide reacts with hydrogen versus carbon monoxide gases and how to control and enhance related chemical reactions.

The inner crust of a neutron star is characterized by the presence of a neutron superfluid. To accurately predict the properties of neutron matter in this state, researchers make theoretical calculations that typically assume that neutrons form “Cooper pairs.” This study used artificial neural networks to make accurate predictions without relying on this assumption.

Oak Ridge National Laboratory scientists are developing a formula for success – by studying how a new type of battery fails. The team’s goal is the design for long-term storage of wind and solar energy, which are produced intermittently, enabling their broader use as reliable energy sources for the electric grid.
