A new platform for quantum information processing, The researchers created Rydberg atoms with unusually large excited atoms near thin optical fibers.
Is making progress towards a new quantum information processing platform that can revolutionize the discovery of materials and drugs and enable safer quantum communication.
Because of its extreme sensitivity to electric and magnetic fields, Rydberg’s atoms have long aroused the interest of physicists.
When combined with optical nanofibers, these hypersensitive atoms can play an important role in new types of quantum devices that can be scaled.
For their research, scientists used a device called a magneto-optical trap to capture a group of rubidium atoms (Rb).
They reduce the temperature of the atom to about 120 micro-Kelvin fractions one degree above absolute zero and guide the nanofibers through the atomic cloud. A new platform for quantum information processing.
Then the scientists excited the Rb atom to be a more energetic state than Rydberg with a beam of 482 nm moving through nanofibers.
These Rydberg atoms that have formed around the surface of the nanofibers are larger than their normal counterparts.
When electrons get energy from atoms, they move away from the nucleus and create larger atoms.
This unusual size increases the sensitivity of atoms to their environment and the presence of other Rideberg atoms.
Through experiments, the scientists brought Rydberg atoms only one nanometer away from optical nanofiber, which allows better interaction between atoms and light that travels in the nanofiber.
Due to their anomalous nature, Rydberg’s atoms escape from the magneto-optic trap.
Scientists are able to understand aspects of Rydberg’s atomic behavior by examining how the loss of atoms depends on the strength and wavelength of light. A new platform for quantum information processing.
The ability to use moving light in optical nanofibers to excite and then control Rydberg atoms can pave the way for quantum communication methods and, at the same time, gradually develop quantum computation, scientists say.
In the future, the researchers hope to be able to further investigate the properties of Rydberg atoms in relation to optical nanofibers.
In future studies, they plan to study even greater Rydberg atoms to explore the possibilities and limitations of this system.
