Physicist disentangles 'Schrodinger's cat' debate
Physicist Art Hobson has offered a solution, within the framework of standard quantum physics, to the long-running debate about the nature of quantum measurement.
Atoms with quantum memory
Order tends towards disorder. This is also true for quantum states. Measurements at the Vienna University of Technology show that in quantum mechanics this transition can be quite different from what we experience ...
Einstein vs quantum mechanics, and why he'd be a convert today
Albert Einstein may be most famous for his mass-energy equivalence formula E = mc2, but his work also laid down the foundation for modern quantum mechanics.
Proving uncertainty: First rigorous formulation supporting Heisenberg's famous 1927 principle
Nearly 90 years after Werner Heisenberg pioneered his uncertainty principle, a group of researchers from three countries has provided substantial new insight into this fundamental tenet of quantum physics ...
Physicists add 'quantum Cheshire Cats' to list of quantum paradoxes
Research team claims to have accurately 'teleported' quantum information ten feet
New principle may help explain why nature is quantum
Like small children, scientists are always asking the question 'why?'. One question they've yet to answer is why nature picked quantum physics, in all its weird glory, as a sensible way to behave. Researchers ...
Quantum reality more complex than previously thought
Imagine you order a delivery of several glass vases in different colors. Each vase is sent as a separate parcel. What would you think of the courier if the parcels arrive apparently undamaged, yet when you ...
D-Wave chip passes rigorous tests
With cutting-edge technology, sometimes the first step scientists face is just making sure it actually works as intended.
Scientists capture first direct images of theoretically predicted magnetic monopoles
(PhysOrg.com) -- Scientists have captured the first direct images of magnetic monopoles which were theoretically conceived by the British-Swiss physicist Dirac in the early 1930s who showed that their existence ...
Physicists prove Heisenberg's intuition correct
An international team of scientists has provided proof of a key feature of quantum physics – Heisenberg's error-disturbance relation - more than 80 years after it was first suggested.
Could classical theory be just as weird as quantum theory?
Quantum steps towards the Big Bang
(Phys.org) —Present-day physics cannot describe what happened in the Big Bang. Quantum theory and the theory of relativity fail in this almost infinitely dense and hot primal state of the universe. Only ...
When parallel worlds collide, quantum mechanics is born
Parallel universes – worlds where the dinosaur-killing asteroid never hit, or where Australia was colonised by the Portuguese – are a staple of science fiction. But are they real? ...
