Scientists Just Proved A Fundamental Quantum Physics Problem is Unsolvable
Scientists have proven for the very first time that one of the most fundamental problems of particle and quantum physics is mathematically unsolvable.
In short, they show that regardless of how no matter how perfectly we can mathematically describe a material on the microscopic level, we are never going to be able to predict its macroscopic behavior. Never.
The work was published in Nature.
Quantum ‘compass’ promises navigation without using GPS
The technology could reduce the damage done by GPS satellite failures or jamming efforts.
Quantum ‘compass’ could allow navigation without relying on satellites
The UK’s first quantum accelerometer for navigation has been demonstrated by a team from Imperial College London and M Squared.
Most navigation today relies on a global navigation satellite system (GNSS), such as GPS, which sends and receives signals from satellites orbiting the Earth. The quantum accelerometer is a self-contained system that does not rely on any external signals.
This is particularly important because satellite signals can become unavailable due to blockages such as tall buildings, or can be jammed, imitated or denied – preventing accurate navigation. One day of denial of the satellite service would cost the UK £1 billion.
Scientists to create ‘truly unhackable’ network based on quantum physics
Scientists are planning to create a network in the Chicago area tapping the principles of quantum physics. The idea is to prove that quantum physics could provide the basis for an unhackable internet.
This, they say, could have wide-ranging impact on communications, computing and national security.
The quantum network development, supported by the US Department of Energy (DOE), will stretch between the DOE’s Argonne National Laboratory and Fermi National Acceleratory Laboratory, a connection that is said will be the longest in the world to send secure information using quantum physics.
