It is now shown that the trans conformer of trifluoromethylhydroxycarbene preferentially rearranges through a quantum-mechanical hydrogen-tunnelling pathway, whereas its cis conformer is unreactive.

The first direct observation of the orbital structure of an excited hydrogen atom has been made by an international team of researchers. The observation was made using a newly developed “quantum ...

Hydrogen-like atoms (or hydrogenic atoms) are atoms with one single electron. Like the hydrogen atom, hydrogen-like atoms are one of the few quantum mechanical problems which can be exactly solved.

Where classical technologies reach their limits, quantum technologies open up new possibilities for research, industry and business. New sensors, simulators, communication networks and computers with ...

So far, they have managed to do so using, for instance, atoms or molecules in quantum mechanical superposition states of being in two places at the same time. At ETH, a team of researchers led by ...

They showed reporters an image of 10,000 laser spots that can contain 10,000 atoms in a 100 x 100 array. “Considering our current capabilities,” he said, “we believe we can get to at least 10,000 ...

Quantum computing could change our perspective on the cosmos. (Illustration: Harmonia Macrocosmica, 1660 / Microsoft, 2022 / Alan Boyle) What does quantum computing have in common with the Oscar ...

Classical computations rely on binary bits, which can be in either of the two states, 0 or 1. In contrast, quantum computing is based on qubits, which can be 0, 1, or a superposition or entanglement ...

When a molecule absorbs light, it undergoes a whirlwind of quantum-mechanical transformations. Electrons jump between energy levels, atoms vibrate, and chemical bonds shift—all within millionths ...
