D-Wave Systems Breaks the 1000 Qubit Quantum Computing Barrier
D-Wave Systems Inc., the world's first quantum computing company, today announced that it has broken the 1000 qubit barrier, developing a processor about double the size of D-Wave’s previous generation and far exceeding the number of qubits ever developed by D-Wave or any other quantum effort. This is a major technological and scientific achievement that will allow significantly more complex computational problems to be solved than was possible on any previous quantum computer.

[Novel] Experiment [again] confirms quantum theory weirdness
The bizarre nature of reality as laid out by quantum theory has survived another test, with scientists performing a famous experiment and proving that reality does not exist until it is measured. Physicists at The Australian National University (ANU) have conducted John Wheeler's delayed-choice thought experiment, which involves a moving object that is given the choice to act like a particle or a wave. Wheeler's experiment then asks - at which point does the object decide?

There Is Growing Evidence that Our Universe Is a Giant Hologram
If a friend told you that we were all living in a giant hologram, you’d probably tell him to lay off the kush. But incredibly, physicists across the world are thinking the same thing: That what we perceive to be a three-dimensional universe might just be the image of a two-dimensional one, projected across a massive cosmic horizon.

New method of quantum entanglement vastly increases how much information can be carried in a photon
A team of researchers led by UCLA electrical engineers has demonstrated a new way to harness light particles, or photons, that are connected to each other and act in unison no matter how far apart they are —a phenomenon known as quantum entanglement.

A 'movie' of ultrafast rotating molecules at a hundred billion per second
Can you imagine how subnano-scale molecules make an ultrafast rotation at a hundred billion per second? Do the ultrafast rotating subnano-scale molecules show a wave-like nature rather than particle-like behavior? The Japanese research team led by Professor Yasuhiro Ohshima at the Tokyo Institute of ...

After 85-year search, massless particle with promise for next-generation electronics found
An international team led by Princeton University scientists has discovered Weyl fermions, an elusive massless particle theorized 85 years ago. The particle could give rise to faster and more efficient electronics because of its unusual ability to behave as matter and antimatter inside a crystal, according to new research.

New theory to lead to radiationless revolution
Physicists have found a radical new way to confine electromagnetic energy without it leaking away, akin to throwing a pebble into a pond with no splash. The theory could have broad ranging applications from explaining dark matter to combating energy losses in future technologies. However, it appears to contradict a fundamental tenet of electrodynamics, that accelerated charges create electromagnetic radiation.

How quantum biology might explain life’s biggest questions
How does a robin know to fly south? The answer might be weirder than you think: Quantum physics may be involved. Jim Al-Khalili rounds up the extremely new, extremely strange world of quantum biology, where something Einstein once called “spooky action at a distance” helps birds navigate, and quantum effects might explain the origin of life itself.

Seeing quantum motion; even one day ripples in the fabric of space-time?
Even large objects obey quantum physics, meaning they are never quite at rest. Researchers have developed a way to detect -- and manipulate -- this underlying quantum motion.
