Two Critical Advances Towards Realization of a Quantum Computer

IBM scientists today unveiled two critical advances towards the realization of a practical quantum computer. For the first time, they showed the ability to detect and measure both kinds of quantum errors simultaneously, as well as demonstrated a new, square quantum bit circuit design that is the only physical architecture that could successfully scale to larger dimensions.

New Mathematical Proof Reveals a Much Tighter Limit on How Fast Quantum Information Can Propagate

If you’re designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but JQI physicists have narrowed the theoretical limits for where that “speed limit” is. The work implies that quantum processors will work more slowly than some research has suggested.

Mathematicians Develop New Method that Simplifies Big Data Using Ideas from Quantum Theory

Analysing the large volumes of data gathered by modern businesses and public services is problematic. Traditionally, relationships between the different parts of a network have been represented as simple links, regardless of how many ways they can actually interact, potentially loosing precious information.

Quantum Processors Could Work More Slowly Than Believed

If you're designing a new computer, you want it to solve problems as fast as possible. Just how fast is possible is an open question when it comes to quantum computers, but physicists at the National Institute of Standards and Technology (NIST) have narrowed the theoretical limits for where that "speed limit" is. The research implies that quantum processors will work more slowly than some research has suggested.

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.
