Schrodinger's cat gets a reality check
It's a century-old debate: what is the meaning of the wave function, the central object of quantum mechanics? Is Schrödinger's cat really dead and alive? ...
Quantum mechanics explains efficiency of photosynthesis
Light-gathering macromolecules in plant cells transfer energy by taking advantage of molecular vibrations whose physical descriptions have no equivalents in classical physics, according to the first unambiguous ...
Physicists 'uncollapse' a partially collapsed qubit
Liquid spacetime: A very slippery superfluid, that's what spacetime could be like
What if spacetime were a kind of fluid? This is the question tackled by theoretical physicists working on quantum gravity by creating models attempting to reconcile gravity and quantum mechanics. Some of ...
Engineers make sound loud enough to bend light on a computer chip
During a thunderstorm, we all know that it is common to hear thunder after we see the lightning. That's because sound travels much slower (768 miles per hour) than light (670,000,000 miles per hour).
Ten of the biggest science and technology stories of 2014 on Phys.org
MIT researchers build an all-optical transistor
Optical computing—using light rather than electricity to perform calculations—could pay dividends for both conventional computers and quantum computers, largely hypothetical devices that could perform ...
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.
Another step toward understanding of high-temperature superconductivity
(Phys.org) —Superconductors can radically change energy management as we know it, but most are commercially unusable because they only work close to absolute zero. A research group at EPFL has now published ...
'Spooky action at a distance' aboard the ISS
(Phys.org) —Albert Einstein famously described quantum entanglement as "spooky action at distance"; however, up until now experiments that examine this peculiar aspect of physics have been limited to relatively ...
Light-matter interaction can turn opaque materials transparent
Tricking the uncertainty principle
(Phys.org) —Caltech researchers have found a way to make measurements that go beyond the limits imposed by quantum physics.
Physicists show self-correcting quantum computers are theoretically possible
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 ...
