Dr. Hyang-Tag Lim's research team at the Center for Quantum Technology at the Korea Institute of Science and Technology (KIST) has implemented a quantum computing algorithm that can estimate interatomic bond distances and ground state energies with chemical accuracy using fewer resources than conventional methods, and has succeeded in performing accurate calculations without the need for additional quantum error mitigation techniques.

One new study, conducted by researchers at the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) and Princeton University, investigated ways to reliably grow diamond at lower temperatures than those currently used. Diamond has properties that make it attractive to the semiconductor industry. With its particular crystal lattice structure, diamond can withstand high electrical voltages. It’s also very good at dissipating heat.

Researchers at the Max Planck Institute for Nuclear Physics in Heidelberg have succeeded in selectively manipulating the motion of the electron pair in the hydrogen molecule. The emission direction of a photoelectron released by light (a photon) relative to the remaining bound electron in the cleaved neutral hydrogen atom can be controlled by the time interval between two laser flashes on the scale of a few hundred attoseconds (10–18 s). The adjustable emission asymmetry is based on the quantum entanglement between the bound electron and the spatially separated emitted electron.

Building on its more than 70 years pioneering the study of fusion energy, the U.S. Department of Energy’s (DOE) Princeton Plasma Physics Laboratory (PPPL) has added a new field to its research portfolio — quantum information science.
