New Molecule Created with Large Permanent Dipole Moment

A proposed pathway to construct quantum computers may be the outcome of research by a University of Oklahoma physics team that has created a new molecule based on the interaction between a highly-excited type of atom known as a Rydberg atom and a ground-state atom. A unique property of the molecule is the large permanent dipole moment, which reacts with an electric field much like a bar magnet reacts with a magnetic field.

Researchers Demonstrate Very High Speed Quantum Switch with Silicon

The team demonstrated a quantum on/off switching time of about a millionth of a millionth of a second - the fastest-ever quantum switch to be achieved with silicon and over a thousand times faster than previous attempts.

Orbital Angular Momentum for Encoding Information Increases Possibility of High-Dimensional Quantum Key Distribution

Researchers at the University of Rochester and their collaborators have developed a way to transfer 2.05 bits per photon by using "twisted light." This remarkable achievement is possible because the researchers used the orbital angular momentum of the photons to encode information, rather than the more commonly used polarization of light.

Highly Connected Quantum Structures May Not Always Support Speed of Quantum Computing

Using the quantum property of superposition, quantum computers will be able to find target items within large piles of data far faster than conventional computers ever could. But the speed of the search will likely depend on the structure of the data.

QDev and QuTech Enter Partnership for Research in Quantum Technologies

Research collaboration What do you do when you have two of the leading giants in the same research field? – compete with each other? – fight each other? – no, you start collaborating. The Center for Quantum Devices, QDev at the Niels Bohr Institute at the University of Copenhagen and QuTech at Delft University of Technology in Holland have therefore entered into an international partnership in the research of quantum technologies. The collaboration will be celebrated with an official ceremony with the attendence of ministers from both countries and the Dutch royal couple.
