For the first time, scientists have tracked electrons moving through exotic materials that may make up the next generation of computing hardware, revealing intriguing properties not found in conventional, silicon-based semiconductors. (more…)
In a step that brings silicon-based quantum computers closer to reality, researchers at Princeton University have built a device in which a single electron can pass its quantum information to a particle of light. The particle of light, or photon, can then act as a messenger to carry the information to other electrons, creating connections that form the circuits of a quantum computer. (more…)
Die Crystalline Mirror Solutions GmbH (CMS) ist aus der experimentellen Grundlagenforschung von Markus Aspelmeyer und Garrett Cole an der Fakultät für Physik der Universität Wien hervorgegangen. Heute ist CMS ein weltweit führender Hersteller von Hochpräzisionsoptik für Lasersysteme und wurde bereits mehrfach ausgezeichnet, zuletzt mit dem 1. Platz in der Kategorie High-Tech beim GEWINN-Jungunternehmerwettbewerb. Ein Beweis dafür, dass Grundlagenforschung eine wichtige Basis für wirtschaftliche Innovationen ist.
Crystalline Mirror Solutions ist ein Pionierunternehmen auf dem Gebiet der laserbasierten Präzisionsmessung. “Unsere Technologie erlaubt erstmals den Einsatz kristalliner Halbleiterspiegel für die konventionelle Laseroptik. Die Spiegel – man spricht von einem sogenannten Bragg-Mirror – bestehen aus einem sehr dünnen, kristallinen Film mit einer genau definierten Abfolge von Halbleiterschichten. Dieser Halbleiterfilm wird direkt mit einem optischen Träger verbunden”, so Markus Aspelmeyer, Professor für Quantum Information on the Nanoscale an der Universität Wien. (more…)
By carefully controlling the position of an atomic-scale diamond defect within a volume smaller than what some viruses would fill, researchers have cleared a path toward better quantum computers and nanoscale sensors. They describe their technique in a paper published in the journal Applied Physics Letters, from AIP Publishing. (more…)
Berkeley Study Provides Unprecedented Details on Ultrafast Processes in Diamond Nitrogen Vacancy Centers
From supersensitive detections of magnetic fields to quantum information processing, the key to a number of highly promising advanced technologies may lie in one of the most common defects in diamonds. Researchers at the Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California (UC) Berkeley have taken an important step towards unlocking this key with the first ever detailed look at critical ultrafast processes in these diamond defects.

Berkeley Lab researchers and their colleagues extend electron spin in diamond for incredibly tiny magnetic detectors
From brain to heart to stomach, the bodies of humans and animals generate weak magnetic fields that a supersensitive detector could use to pinpoint illnesses, trace drugs – and maybe even read minds. Sensors no bigger than a thumbnail could map gas deposits underground, analyze chemicals, and pinpoint explosives that hide from other probes.
Now scientists at the U.S. Department of Energy’s Lawrence Berkeley National Laboratory (Berkeley Lab) and the University of California at Berkeley, working with colleagues from Harvard University, have improved the performance of one of the most potent possible sensors of magnetic fields on the nanoscale – a diamond defect no bigger than a pair of atoms, called a nitrogen vacancy (NV) center. (more…)
Yale University scientists have found a way to observe quantum information while preserving its integrity, an achievement that offers researchers greater control in the volatile realm of quantum mechanics and greatly improves the prospects of quantum computing.
Quantum computers would be exponentially faster than the most powerful computers of today. (more…)
*Tiny crystal towers enlighten understanding of photon emission, could inspire diamond microchips for quantum computing*
Building on earlier work, scientists and engineers recently developed a manufacturing process that allows them to craft an assortment of miniature, silver-plated-diamond posts that enable greater control of light producing photons at the atomic scale. The research could prove important for future generations of quantum computers.
Prior research demonstrated how nanowires carved in impurity-laden diamond crystal could efficiently emit individual photons, an important discovery for using light to rapidly read and write quantum-based data. (more…)
