Quantum Leaps, Long Assumed to Be Instantaneous, Take Time

 

 

 

 

 

When quantum mechanics was first developed a century ago as a theory for understanding the atomic-scale world, one of its key concepts was so radical, bold and counter-intuitive that it passed into popular language: the “quantum leap.” Purists might object that the common habit of applying this term to a big change misses the point that jumps between two quantum states are typically tiny, which is precisely why they weren’t noticed sooner. But the real point is that they’re sudden. So sudden, in fact, that many of the pioneers of quantum mechanics assumed they were instantaneous.

Quantum Teleportation Enters the Real World

 

 

 

 

 

 

Two separate teams of scientists have taken quantum teleportation from the lab into the real world. Researchers working in Calgary, Canada and Hefei, China, used existing fiber optics networks to transmit small units of information across cities via quantum entanglement — Einstein’s “spooky action at a distance.”Stepping Outside the LabAccording to quantum mechanics, some objects, like photons or electrons, can be entangled.

High-Intensity Interval Training

 

 

 

 

 

Looking for a way to add variety to your exercise plan while taking your fitness to the next level? High-intensity interval training (HIIT) is a cardiorespiratory training technique that alternates brief speed and recovery intervals to increase the overall intensity of your workout. HIIT is used by athletes and everyday exercise enthusiasts to reach performance goals and enhance fitness and well-being.
