A Rydberg atom is an excited atom with one or more electrons that have a very high principal quantum number, n. The higher the value of n, the farther the electron is from the nucleus, on average.

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 ...

A team of researchers from the 5th Institute of Physics at the University of Stuttgart is making important progress in the field of quantum simulation and quantum computing based on Rydberg atoms by ...

Quantum Computer science legend, Dr John Preskill, just delivered a Q2B Quantum computer 2023 keynote talk on the state of Quantum Error correction with quantum ...

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 ...

A group of University of Oklahoma researchers led by Dr. James P. Shaffer, Homer L. Dodge Department of Physics and Astronomy, have discovered giant Rydberg molecules with a bond as large as a red ...

As the charge of the ion deforms the Rydberg atom in a very specific way, the bond between the two particles emerges. Rubidium cloud cooled down close to the absolute zero To verify and study the ...

Researchers have engineered a new, exotic state of matter in a lab in Houston – a giant atom filled with other atoms. The team, from the Vienna University of Technology and Harvard University, were ...

You may be familiar with matryoshka dolls: nested sets of painted figurines that fit within painted figurines. In the case of wooden dolls, the concept is pretty straightforward: hollow out a large ...
