July 20 (UPI) -- The creators of the world's fastest manmade rotor believe their invention will boost the study of quantum mechanism, the branch of physic devoted to the behavior of subatomic particles. The new rotor can spin at a rate of 60 billion revolutions per minute. Most airplane turbines top out at 3,000 revolutions per minute. Scientists described their impressive new device this week in the journal Physical Review Letters. "This study has many applications, including material science," Tongcang Li, an assistant professor of physics and astronomy at Purdue University, said in a news release. "We can study the extreme conditions different materials can survive in." The rotor is composed of a tiny silica dumbbell. Scientists used a laser to levitate the dumbbell inside a vacuum. T...

Quantum computing has taken a step forward with the development of a programmable quantum processor made with silicon.The team used microwave energy to align two electron particles suspended in silicon, then used them to perform a set of test calculations.By using silicon, the scientists hope that quantum computers will be more easy to control and manufacture. The research was published in the journal Nature.The old adage of Schrödinger's Cat is often used to frame a basic concept of quantum theory. We use it to explain the peculiar, but important, concept of superposition; where something can exist in multiple states at once.For Schrodinger's feline friend - the simultaneous states were dead and alive.Superposition is what makes quantum computing so potentially powerful.Standard computer
