Researchers Explore Qubits for Quantum Simulation on a Smaller Scale

While the Martinis Lab at UC Santa Barbara has been focusing on quantum computation, former postdoctoral fellow Pedram Roushan and several colleagues have been exploring qubits (quantum bits) for quantum simulation on a smaller scale. Their research appears in the current edition of the journal Nature.

Study Results Pave Way to Better Understand Interstellar Chemistry

Silicon, which is one of the most common elements in the Earth's crust, is also sprinkled abundantly throughout interstellar space. The only way to identify silicon-containing molecules in the far corners of the cosmos - and to understand the chemistry that created them - is to observe through telescopes the electromagnetic radiation the molecules emit.

Quantum Particles of Heat Limit Noise in a Microwave Amplifier

As part of an international collaboration, scientists at Chalmers University of Technology have demonstrated how noise in a microwave amplifier is limited by self-heating at very low temperatures. The results will be published in the prestigious journal Nature Materials. The findings can be of importance for future discoveries in many areas of science such as quantum computers and radio astronomy.

New ALMA Data Shows First Steps of Galaxy Merger in Early Universe

Nestled among a triplet of young galaxies more than 12.5 billion light-years away is a cosmic powerhouse: a galaxy that is producing stars nearly 1,000 times faster than our own Milky Way. This energetic starburst galaxy, known as AzTEC-3, together with its gang of calmer galaxies may represent the best evidence yet that large galaxies grow from the merger of smaller ones in the early Universe, a process known as hierarchical merging.

Interactions in Certain Quantum Materials Hold Potential for Better Electronics

Scientists have discovered that interactions in certain quantum materials could naturally produce the effects needed for ultra-efficient computers and other electronics.The field of spintronics — a short form of spin transport electronics — seeks to understand and power electronic devices using the quantum property known as electron spin rather than an electron’s charge. Spintronics could lead to efficient circuits and electrical devices that do not waste energy through friction and heat.

Study Findings Provide New Insights into Global Architecture of Planetary Systems

Researchers studying what appears to be a beefed-up version of our solar system have discovered that it is encased in a halo of fine dust. The findings are based on infrared data from NASA's Spitzer Space Telescope and the European Space Agency's Herschel Space Observatory, in which NASA is a partner.
