Quantum computing: Cold chips can control qubits

Researchers and engineers from QuTech in the Netherlands and from Intel Corp., jointly designed and tested a chip to control qubits that can operate at extremely low temperatures, and opens the door to solving the "wiring ...

Study finds income affects bus ridership in bad weather

Temperature extremes and heavy rain reduce weekday bus ridership in Lane County, except in low-income neighborhoods where residents have few alternatives for transportation, according to a University of Oregon study.

Extreme heat increasing in both summer and winter

A new study shows extreme heat events both in the summer and in the winter are increasing across the U.S. and Canada, while extreme cold events in summer and winter are declining.

Pushing the extra cold frontiers of superconducting science

Measuring the properties of superconducting materials in magnetic fields at close to absolute zero temperatures is difficult, but necessary to understand their quantum properties. How cold? Lower than 0.05 Kelvin (-272°C).

Research team uses excitons to take electronics into the future

Excitons could revolutionize the way engineers approach electronics. A team of EPFL researchers has created a new type of transistor—one of the components of circuits—using excitons instead of electrons. Notably, their ...

Quantum mechanics: entanglements in ultracold atomic clouds

A system's state is characterised as entangled or quantum correlated if two or more particles cannot be described as a combination of separate, independent states but only as a whole. Researchers at the Kirchhoff Institute ...

Fix for synchrotron research flaw could improve results

University of Saskatchewan researchers have found that chemicals commonly used to protect samples in synchrotron experiments actually help to damage those samples, potentially misleading scientists around the world.

Tunable diamond string may hold key to quantum memory

A quantum internet promises completely secure communication. But using quantum bits or qubits to carry information requires a radically new piece of hardware—a quantum memory. This atomic-scale device needs to store quantum ...
