Now, for the first time, a team of Harvard scientists has demonstrated the survival of quantum coherence in a chemical reaction involving ultracold molecules. These findings highlight the potential of harnessing chemical reactions for future applications in quantum information science.

Shortcut to Success: Toward Fast and Robust Quantum Control Through Accelerating Adiabatic Passage

Shortcut to Success: Toward Fast and Robust Quantum Control Through Accelerating Adiabatic Passage

March 10, 2024
In work published in Physical Review Letters researchers at Osaka University's Institute of Scientific and Industrial Research (SANKEN) used "the shortcuts to the adiabaticity (STA)" method to greatly speed-up the adiabatic evolution of spin qubits. The spin flip fidelity after pulse optimization can be as high as 97.8% in GaAs quantum dots. This work may be applicable to other adiabatic passage and may be useful for fast and high-fidelity quantum control.

USTC Observes Third-order Exceptional Line in Nitrogen-vacancy Spin System

February 10, 2024
Research teams led by Academician DU Jiangfeng and Prof. RONG Xing from CAS Key Laboratory of Microscale Magnetic Resonance of University of Science and Technology of China (USTC) have systematically studied the relations between symmetries and high-order non-Hermitian exceptional points (EPs), and observed the third-order exceptional line (EL) in a nitrogen-vacancy (NV) spin system.
