Quantum physics first: Researchers observe single photons in two-slit interferometer experiment
Quantum mechanics is famous for saying that a tree falling in a forest when there's no one there doesn't make a sound. Quantum mechanics also says that if anyone is listening, it interferes with and changes the tree. And ...

HP Labs find memristors can compute (w/ Video)
(PhysOrg.com) -- Researchers at HP Labs, the central research arm of HP, have discovered that a resistor with memory, a “memristor” can also perform logic operations. This means chips storing data may also be able to ...
Using quantum smoothing for optical phase estimation
(PhysOrg.com) -- "There are many situations where we need to measure the classical properties of a quantum system," Elanor Huntington tells PhysOrg.com. "Optical phase estimation is one of these techniques, and it is central ...
