Tesla reportedly eliminates its PR department
Posted by Genevieve Klien in categories: sustainability, transportation
Tesla apparently has a new strategy for dealing with journalists: Don’t deal with them at all.
The electric car giant has dissolved its global public relations team, leaving the press with no formal point of contact at the world’s most valuable automaker, a new report says.
Essentially every staffer who used to work in Tesla’s PR office has either moved to a different position at the company or left altogether, according to electric vehicle industry blog Electrek, which said the move to disband the department was confirmed “at the highest level at Tesla.”

Researchers crack quantum physics puzzle
Posted by Quinn Sena in categories: particle physics, quantum physics
Scientists have re-investigated a sixty-year-old idea by an American physicist and provided new insights into the quantum world.
The research, which took seven years to complete, could lead to improved spectroscopic techniques, laser techniques, interferometric high-precision measurements and atomic beam applications.
Quantum physics is the study of everything around us at the atomic level, atoms, electrons and particles. Atoms and electrons which are so small, one billion placed side by side could fit within a centimeter. Because of the way atoms and electrons behave, scientists describe their behavior as like waves.

Stanene is ‘100% efficient’, could finally replace copper wires in silicon chips
Posted by Quinn Sena in categories: computing, particle physics
Move over, graphene and carbyne — stanene, with 100% electrical efficiency at temperatures up to 100 degrees Celsius (212F), is here, and it wants to replace the crummy, high-resistance copper wires that are a big limiting factor in current computer chips. Where graphene is a single-atom-thick layer of carbon, stanene is a single-atom-thick layer of tin.

UK completes fusion research facility
Posted by Quinn Sena in categories: business, government, nuclear energy
Harworth Group plc has announced the completion of the UK Atomic Energy Authority’s (UKAEA’s) new nuclear fusion technology research facility at the Advanced Manufacturing Park in Rotherham, South Yorkshire. When it opens later this year, the 2500-square-metre facility will develop and test joining technologies for fusion materials and components, including novel metals and ceramics.
Property developer Harworth said completion of the GBP22 million (USD28 million) Fusion Technology facility triggers UKAEA’s 20-year lease with Harworth at a rent in line with other manufacturers at the Advanced Manufacturing Park. UKAEA will now prepare the building prior to taking formal occupation of it later this year.
The new facility is being funded as part of the government’s Nuclear Sector Deal delivered through the Department for Business, Energy and Industrial Strategy. An additional GBP2 million of investment came from Sheffield City Region’s Local Growth Fund.

Intel created a superconducting test chip for quantum computing
Posted by Quinn Sena in categories: computing, quantum physics
Circa 2017
Quantum computing is the next big technological revolution, and it’s coming sooner than you might think. IBM unveiled its own quantum processor this past May, scientists have been experimenting with silicon-laced diamonds (and basic silicon, too) as a quantum computing substrate, Google is already looking at cloud-based solutions and Microsoft is already creating a new coding language for the technology. Now Intel has taken another big step towards a quantum computing reality: the company has created a new superconducting chip using advanced material science and manufacturing techniques, and delivered it to Intel’s research partner in the Netherlands, QuTech.

Solid-state qubits integrated with superconducting through-silicon vias
Posted by Quinn Sena in categories: computing, engineering, quantum physics
O,.o.
As superconducting qubit circuits become more complex, addressing a large array of qubits becomes a challenging engineering problem. Dense arrays of qubits benefit from, and may require, access via the third dimension to alleviate interconnect crowding. Through-silicon vias (TSVs) represent a promising approach to three-dimensional (3D) integration in superconducting qubit arrays—provided they are compact enough to support densely-packed qubit systems without compromising qubit performance or low-loss signal and control routing. In this work, we demonstrate the integration of superconducting, high-aspect ratio TSVs—10 μm wide by 20 μm long by 200 μm deep—with superconducting qubits. We utilize TSVs for baseband control and high-fidelity microwave readout of qubits using a two-chip, bump-bonded architecture. We also validate the fabrication of qubits directly upon the surface of a TSV-integrated chip. These key 3D-integration milestones pave the way for the control and readout of high-density superconducting qubit arrays using superconducting TSVs.
