If you’ve read anything about quantum computers, you may have encountered the statement, “It’s like computing with zero and one at the same time.” That’s sort of true, but what makes quantum computers exciting is something spookier: entanglement.

A new quantum device entangles 20 quantum bits together at the same time, making it perhaps one of the most entangled, controllable devices yet. This is an important milestone in the quantum computing world, but it also shows just how much more work there is left to do before we can realize the general-purpose quantum computers of the future, which will be able to solve big problems relating to AI and cybersecurity that classical computers can’t.

“We’re now getting access to single-particle-control devices” with tens of qubits, study author Ben Lanyon from the Institute for Quantum Optics and Quantum Information in Austria told Gizmodo. Soon, “we can get to the level where we can create super-exotic quantum states and see how they behave in the lab. I think that’s very exciting.”

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics.

The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they have interacted.

Until his death, Einstein remained convinced that entanglement showed how quantum mechanics was incomplete. Schrödinger thought that entanglement was the defining feature of the new physics, but this didn’t mean that he accepted it lightly.

For the first time, we’ve made a molecule by pressing two atoms together to make them bond on command. This could help build better qubits for quantum computers.

In the summer of 1935, the physicists Albert Einstein and Erwin Schrödinger engaged in a rich, multifaceted and sometimes fretful correspondence about the implications of the new theory of quantum mechanics. The focus of their worry was what Schrödinger later dubbed entanglement: the inability to describe two quantum systems or particles independently, after they have interacted.

Until his death, Einstein remained convinced that entanglement showed how quantum mechanics was incomplete. Schrödinger thought that entanglement was the defining feature of the new physics, but this didn’t mean that he accepted it lightly. “I know of course how the hocus pocus works mathematically,” he wrote to Einstein on July 13, 1935. “But I do not like such a theory.” Schrödinger’s famous cat, suspended between life and death, first appeared in these letters, a byproduct of the struggle to articulate what bothered the pair.

The problem is that entanglement violates how the world ought to work. Information can’t travel faster than the speed of light, for one. But in a 1935 paper, Einstein and his co-authors showed how entanglement leads to what’s now called quantum nonlocality, the eerie link that appears to exist between entangled particles. If two quantum systems meet and then separate, even across a distance of thousands of lightyears, it becomes impossible to measure the features of one system (such as its position, momentum and polarity) without instantly steering the other into a corresponding state.

In its early life, the Earth would have been peppered nearly continuously by asteroids smashing into our young planet. These fiery collisions made our world what it is today. It may seem like things have changed since then, given the vast assortment of life and wide blue oceans—and things have indeed changed. At least in some respects. However, Earth still receives thousands of tons of matter from space, but this is in the form of microscopic dust particles (as opposed to recurrent, energetic collisions).

Fortunately, in modern times, a large asteroid colliding with the surface of the Earth happens only very rarely. Nevertheless, it does happen from time to time.

As most are probably already aware, it is widely believed that an asteroid initiated the dinosaurs’ extinction some 65 million years ago. And more recently, the Russian Chelyabinsk meteor hit our planet in February of 2013. It entered at a shallow angle at 60 times the speed of sound. Upon contact with our atmosphere, it exploded in an air burst. The size of this body of rock (before it burned up and shattered) is estimated to be around 20 meters (across) and it weighed some 13,000 metric tons.

WE ARE THE UNIVERSE BECOMING CONSCIOUS OF ITSELF!

Science and technology have relatively bridged the gap between man and the universe throughout the history of time. Yet there remains a lot more to be discovered.

From theories explaining gravity to establishing atoms as the building blocks of all matter, scientific developments have come a long way to introduce man into the hidden truths of the world.

In principle, a wormhole-like scenario is possible, but a wormhole tends to close before objects or other matter could pass through it. As far as we know, it’s unlikely we could construct a wormhole that stays open long enough for us to get to a distant part of the universe.

That’s really the issue: Can you keep a wormhole open?

Everything around us is made of atoms, but it turns out that the building blocks of the Universe are far stranger than that.

Our known universe may end the same way it was created: With a big, sudden bang.

That’s according to new research from a group of Harvard physicists, who found that the destabilization of the Higgs Boson — a tiny quantum particle that gives other particles mass — could lead to a huge explosion of energy that would consume everything in the known universe.

The energy released by the event would destabilize the laws of physics and chemistry.
