IQC Quantum Researcher to Participate in AAAS Annual Meeting

Quantum information processing promises not only breakthroughs for computing, communications and cryptography, but it can also help us devise tools for navigating and controlling the nano-scale world. Sensors that operate according to quantum mechanics may achieve sensitivity, selectivity, precision and robustness far beyond their classical counterparts.

Study on Dopant Cobalt Atoms May Lead to New Types of Superconductors

Over the last quarter century, scientists have discovered a handful of materials that can be converted from magnetic insulators or metals into “superconductors” able to carry electrical current with no energy loss—an enormously promising idea for new types of zero-resistance electronics and energy-storage and transmission systems.

Multi-Particle Quantum Walk for Universal Computation

The IQC team of Andrew Childs (Associate Professor of Combinatorics and Optimization), David Gosset (Post-Doctoral Fellow) and Zak Webb (PhD student) have proposed a new universal computational model. This model has the potential to become an architecture for a scalable quantum computer without the need to actively manipulate qubits during the computation. The team’s findings will be published in the February 15, 2013 issue of Science.

Researchers Reverse Quantum Measurement Using Quantum Error Correction Protocol

A team of physicists at the University of Innsbruck, Austria, performed an experiment that seems to contradict the foundations of quantum theory – at first glance. The team led by Rainer Blatt reversed a quantum measurement in a prototype quantum information processor. The experiment is enabled by a technique that has been developed for quantum error correction in a future quantum computer.

NASA's Fermi Reveals First Clear-Cut Evidence for Birth of Cosmic Rays

A new study using observations from NASA's Fermi Gamma-ray Space Telescope reveals the first clear-cut evidence the expanding debris of exploded stars produces some of the fastest-moving matter in the universe. This discovery is a major step toward understanding the origin of cosmic rays, one of Fermi's primary mission goals.

First Step Towards Creating Exotic Mechanical Quantum States

This work represents the first step towards creating exotic mechanical quantum states. For example, the transfer makes it possible to create a state in which the resonator simultaneously vibrates and doesn’t vibrate, says Mika Sillanpää, professor at Aalto University, who runs the research group.
