Quantum physicists shed new light on relation between entanglement and nonlocality
(PhysOrg.com) -- New research from the University of Bristol may disprove a long-standing conjecture made by one of the founders of quantum information science: that quantum states featuring positive partial transpose, ...
Quantum physics is the focus of Nobel buzz
Three physicists whose research on entangled particles plays a key role in attempts to develop super-fast quantum computers could be in the running for the 2011 Nobel Prize in physics on Tuesday.
