Quantum simulations of the hydroxide anion and hydroxyl radical are reported, employing variational quantum algorithms for near-term quantum devices. The energy of each species is calculated along the dissociation curve, to obtain information about the stability of the molecular species being investigated. It is shown that simulations restricted to valence spaces incorrectly predict the hydroxyl radical to be more stable than the hydroxide anion. Inclusion of dynamical electron correlation from nonvalence orbitals is demonstrated, through the integration of the variational quantum eigensolver and quantum subspace expansion methods in the workflow of N-electron valence perturbation theory, and shown to correctly predict the hydroxide anion to be more stable than the hydroxyl radical, provided that basis sets with diffuse orbitals are also employed.

The ERNIE bot could be China’s most notable entry in the race to create lifelike AI bots.

One of the world’s biggest AI (artificial intelligence) and internet firms, Baidu, had its shares skyrocket more than 14 percent on Tuesday after the Beijing-based search engine titan announced it would launch its own ChatGPT-style service.

What is ERNIE?

With its state-of-the-art design, it provides endless possibilities for exploration and adventure!

A research team at the Chinese University in Hong Kong recently demonstrated that, despite giving off an aura of extraterrestrial technology to onlookers, it’s not out-of-this-world for objects to traverse between water and air in the blink of an eye.
