Quantum Sensor Can Identify Electromagnetic Signs of Any Frequency

MIT researchers have developed a method to enable quantum sensors to detect any arbitrary frequency, with no loss of their ability to measure nanometer-scale features. Quantum sensors detect the most minute variations in magnetic or electrical fields, but until now they have only been capable of detecting a few specific frequencies, limiting their usefulness....

Hydrogen atoms are shattered together at...

Laws of Physics bent: Time Crystals “Impossible” but Obey Quantum Physics

In a new experiment, scientists created two time crystals inside the superfluid, and brought them to touch. Credit: SciTechdaily.Time crystals were long considered impractical because their continuous movement would seem to challenge the laws of physics. Utilizing quantum physics, scientists have developed time crystals and now proved that they can power helpful tools in...

Self-Assembled Logic Circuits Made From Proteins

Researchers have developed self-assembled, protein-based circuits that can do simple logic functions in proof-of-concept research. The work demonstrates that it is possible to develop stable digital circuits that benefit from an electron's properties at quantum scales.Molecular circuitsOne of the stumbling blocks in developing molecular circuits is that the circuits become unreliable as the circuit...

The Large Hadron Collider Has Restarted

Scientists have been upgrading the Large Hadron Collider (pictured) for the past few years. On April 22, they successfully directed protons through the upgraded accelerator.

Nuclear Fusion: How Thrilled Should We Be?

Fusion could create more energy than any other process that could be produced on Earth. Credit: ShutterstockThere has been significant excitement about recent results from the Joint European Torus (JET) facility in the UK, suggesting that the dream of nuclear fusion power is inching closer to reality. We know that fusion works-- it is the...

A Brand-New Concept to Describe the Openness of Metal Oxides

The electrons of some metal oxides, due to their vast effective mass when combined with the ionic lattice of the material, can not comply with the electric field of light and allow it to pass through the material. Transparent and conductive materials are made use of in smartphone touch displays and solar panels for...
