It just goes to show that one of the most potent weapons in science is the ability to keep an open, critical mind.

Two recent studies have confirmed that the “spooky action at a distance” that so upset Albert Einstein — the notion that two entangled particles separated by long distances can instantly affect each other — has been proven to work in a stunning array of different experimental setups.

One experiment closed two of the three loopholes in proofs of spooky action at a distance. Another found that quantum entanglement works over astonishingly large distances. And future tests are focused on making the final loophole as small as possible. [8 Ways You Can See Einstein’s Theory of Relativity in Real Life]

If the holographic principle does indeed describe our universe, it could help resolve many inconsistencies between relativistic physics and quantum physics, including the black hole information paradox. It would also offer researchers a way to solve some very tough quantum problems using relatively simple gravitational equations. But before we can be sure that we’re living in the Matrix, there’s still a lot of work to be done.

“We did this calculation using 3D gravitational theory and 2D quantum field theory, but the universe actually has three spatial dimensions plus time,” Grumiller said. “A next step is to generalize these considerations to include one higher dimension. There are also many other quantities that should correspond between gravitational theory and quantum field theory, and examining these correspondences is ongoing work.”

Entanglement is one of the strangest phenomena predicted by quantum mechanics, the theory that underlies most of modern physics. It says that two particles can be so inextricably connected that the state of one particle can instantly influence the state of the other, no matter how far apart they are.

Just one century ago, entanglement was at the center of intense theoretical debate, leaving scientists like Albert Einstein baffled. Today, however, entanglement is accepted as a fact of nature and is actively being explored as a resource for future technologies including quantum computers, quantum communication networks, and high-precision quantum sensors.

Entanglement is also one of nature’s most elusive phenomena. Producing entanglement between particles requires that they start out in a highly ordered state, which is disfavored by thermodynamics, the process that governs the interactions between heat and other forms of energy. This poses a particularly formidable challenge when trying to realize entanglement at the macroscopic scale, among huge numbers of particles.

Engineers from the University of New South Wales, Australia, have made an important breakthrough that brings quantum computers one step closer to reality.

The team created a quantum version of a standard computer code within a silicon chip. The discovery shows that it is possible to construct realistic and reliable quantum computers.

Quantum computers have the potential to solve problems much more quickly than any computer that exists today, as they combine the rules of informatics to phenomena of quantum mechanics that are not observed in everyday life. Namely, the principle of superposition, popularized by Schrödinger’s cat being both alive and dead, and entanglement.

D-Wave Systems Inc., the world’s first quantum computing company, announced that Los Alamos National Laboratory will acquire and install the latest D-Wave quantum computer, the 1000+ qubit D-Wave 2X™ system. Los Alamos, a multidisciplinary research institution engaged in strategic science on behalf of national security, will lead a collaboration within the Department of Energy and with select university partners to explore the capabilities and applications of quantum annealing technology, consistent with the goals of the government-wide National Strategic Computing Initiative. The National Strategic Computing Initiative, created by executive order of President Barack Obama in late July, is intended “to maximize [the] benefits of high-performance computing (HPC) research, development, and deployment.”

“Eventually Moore’s Law (that predicted that the number of transistors on an integrated circuit would double every two years) will come to an end,” said John Sarrao, associate director for Theory, Simulation, and Computation at Los Alamos. “Dennard Scaling (that predicted that performance per watt of computing would grow exponentially at roughly the same rate) already has. Beyond these two observations lies the end of the current ‘conventional’ computing era, so new technologies and ideas are needed.”

“As conventional computers reach their limits in terms of scaling and performance per watt, we need to investigate new technologies to support our mission,” said Mark Anderson of the Laboratory’s Weapons Physics Directorate. “Researching and evaluating quantum annealing as the basis for new approaches to address intractable problems is an essential and powerful step, and will enable a new generation of forward thinkers to influence its evolution in a direction most beneficial to the nation.”

What seemed to be flaws in the structure of a mystery metal may have given physicists a glimpse into as-yet-undiscovered laws of the universe.

The qualities of a high-temperature superconductor — a compound in which electrons obey the spooky laws of quantum physics, and flow in perfect synchrony, without friction — appear linked to the fractal arrangements of seemingly random oxygen atoms.

Those atoms weren’t thought to matter, especially not in relation to the behavior of individual electrons, which exist at a scale thousands of times smaller. The findings, published Aug. 12 in Nature, are a physics equivalent of discovering a link between two utterly separate dimensions.

A team of quantum physicists in Martinis Lab have come a step closer in creating the circuitry that would allow them to process super computing done by quantum computers. The revolution is promised by the new quantum bits (qubits) compared to the previously done classical computing. Qubits infuse the system with high levels of reliability and speed, thus building foundations for large scale superconducting quantum computers.

Till now computing has been done by classical methods in which the bits were either in states 0 or 1, but qubits exist at all the positions simultaneously, in different dimensions. This special property of being omnipresent is called ‘superpositioning’. However, one of the difficulties is keeping the qubits stable to reproduce same result each time. This superpositioning characteristic makes qubits prone to ‘flipping’, therefore making it difficult to work with.

Julian Kelly, graduate student researcher and co-lead author of a research paper that was published in the journal Nature said:
