A University at Buffalo physicist has received two U.S. Department of Defense grants totaling $1.1 million to study the quantum dynamics that could help advance neutral-atom quantum computing.

Rydberg atoms are highly sensitive atoms, as one electron is only loosely bound. Compared to 'normal' atoms which are one tenth of a nanometer in size those giant atoms are ~100 nanometers large. Due ...

Rydberg atoms, which are atoms in a highly excited state, have several unique and advantageous properties, including a particularly long lifetime and large sensitivities to external fields. These ...

Physicists at the Max Planck Institute of Quantum Optics in Garching near Munich, have now gained fundamental insights into a particular kind of atomic ensemble – a so-called Rydberg gas – that might ...

When it comes to quantum mechanics, I try to avoid writing about purely theoretical results. This is especially true of quantum computing, where, in the not-too-distant past, every researcher would ...

How and when quantum computers will start operating still remains uncertain. Even so, there are various suggestions for systems they could use to compute with. One example is an ultra-cold ensemble of ...

These Rydberg atoms have grown in size a thousand times compared to typical atoms. As the charge of the ion deforms the Rydberg atom in a very specific way, the bond between the two particles emerges.

Classical physics describes how big things behave and interact in our physical world. Throw a ball into the air, and you know it will go up and come down in a predictable path every time. In the ...
