Optical Control of TI Photoemission Offers Potential Applications in Quantum Computing

Plain-looking but inherently strange crystalline materials called 3D topological insulators (TIs) are all the rage in materials science. Even at room temperature, a single chunk of TI is a good insulator in the bulk, yet behaves like a metal on its surface.

Naturally Occurring Topological Insulator Retrieved from Abandoned Gold Mine

In a step toward understanding and exploiting an exotic form of matter that has been sparking excitement for potential applications in a new genre of supercomputers, scientists are reporting the first identification of a naturally occurring "topological insulator" (TI). Their report on discovery of the material, retrieved from an abandoned gold mine in the Czech Republic, appears in the ACS journal Nano Letters.

Superconducting Quantum-Interference Devices Help Extract Microwave Photons out of Vacuum's Quantum Noise

The researchers conducted a mirror experiment to show that by changing the position of the mirror in a vacuum, virtual particles can be transformed into real photons that can be experimentally observed. In a vacuum, there is energy and noise, the existence of which follows the uncertainty principle in quantum mechanics.

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.

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.
