The Hall effect, discovered in 1879, is observable when a Hall voltage perpendicular to the current is produced across a conductor under a magnetic field. Although the Hall effect was discovered in a sheet of gold leaf by ...

(Phys.org) —For all of their differences, classical and quantum communication have at least one thing in common: the importance of being able to store optical information. That being said, optical storage is a complex process ...
Where are the quantum computers? Aren't they supposed to be speeding up decryption and internet searches? After two decades of research, you still can't find them in stores. Well, it took two decades or more of research dedicated ...

(Phys.org) —The ubiquitous classical digital computer encodes data in bits (a portmanteau of binary and digits) in either a 0 or 1 state. On the other hand, while a quantum computer also uses 0/1 data representation, these ...
In the study of ways to determine the position of and manipulate magnetic nanoparticles – a capability that would benefit a wide range of applications – there's good news and bad: While a magnetic gradient force field ...
