An Ultra-Precise Clock Shows How to Link the Quantum World With Gravity
The infamous twin paradox sends the astronaut Alice on a blazing-fast space voyage. When she returns to reunite with her twin, Bob, she finds that he has aged much faster than she has. It’s a well-known but perplexing result: Time slows if you’re moving fast.

Otherworldly 'time crystal' made inside Google quantum computer could change physics forever
Researchers working in partnership with Google may have just used the tech giant's quantum computer to create a completely new phase of matter — a time crystal. With the ability to forever cycle between two states without ever losing energy, time crystals dodge one of the most important laws of physics — the second law of thermodynamics, which states that the disorder, or entropy, of an isolated system must always increase.

Shanghai scientists set space teleportation record
It first hit our television sets on Sept. 8, 1966. The television show was called Star Trek, and, it featured a bold group of space travellers aboard the starship Enterprise. It was then that we were formally introduced to teleportation — a cool concept that allowed the ship to beam people and things to any coordinate.

Researchers find a way to check that quantum computers return accurate answers
Quantum computers are advancing at a rapid pace and are already starting to push the limits of the world's largest supercomputers. Yet, these devices are extremely sensitive to external influences and thus prone to errors which can change the result of the computation. This is particularly challenging for quantum computations that are beyond the reach of our trusted classical computers, where we can no longer independently verify the results through simulation.

NSA: We 'don't know when or even if' a quantum computer will ever be able to break today's public-key encryption
America's National Security Agency has published an FAQ about quantum cryptography, saying it does not know "when or even if" a quantum computer will ever exist to "exploit" public-key cryptography. In the document, titled Quantum Computing and Post-Quantum Cryptography, the NSA said it "has to produce requirements today for systems that will be used for many decades in the future."

Google researchers made a time crystal inside a quantum computer
A unique phase of matter called a time crystal, which can in theory flip between two configurations forever with no energy input necessary, has been created inside a quantum computer built by Google. It is one of the first real-world problems solved by a quantum computer, and could also be harnessed to improve them.

Is Consciousness Bound by Quantum Physics? We're Getting Closer to Finding Out
One of the most important open questions in science is how our consciousness is established. In the 1990s, long before winning the 2020 Nobel Prize in Physics for his prediction of black holes, physicist Roger Penrose teamed up with anesthesiologist

Highly programmable quantum simulator operates with up to 256 qubits
Physicists have demonstrated a large-scale, programmable quantum simulator, featuring a precisely-arranged two-dimensional array of 256 quantum bits (qubits). Designed by a team headed up at Harvard University, the system uses arrays of highly focused laser beams to trap individual atoms and drag them into desirable arrangements.

Quantum Computing: The Cause of the Next Crypto Crash
The notion that a quantum computer might someday break bitcoin is quickly gaining ground. That’s because quantum computers are becoming powerful enough to factor large prime numbers, a critical component of bitcoin’s public key cryptography. Quantum computers rely on what is known as Shor’s algorithm to achieve this feat. Shor’s algorithm dramatically shortens the time required to solve factorization problems. It's also tailor-made for quantum computing, as it exploits the "superposition" of states used in quantum computing.

Researchers build first modular quantum brain sensor, record signal
A team of scientists at the University of Sussex have for the first time built a modular quantum brain scanner, and used it to record a brain signal. This is the first time a brain signal has been detected using a modular quantum brain sensor anywhere in the world. It's a major milestone for all researchers working on quantum brain imaging technology because modular sensors can be scaled up, like Lego bricks.

Some Scientists Believe the Universe Is Conscious
Sounds like a bad trip ... but what if it's true? In upcoming research, scientists will attempt to show the universe has consciousness. Yes, really. No matter the outcome, we’ll soon learn more about what it means to be conscious—and which objects around us might have a mind of their own.

Wormhole Tunnels in Spacetime May Be Possible, New Research Suggests
In the early days of research on black holes, before they even had that name, physicists did not yet know if these bizarre objects existed in the real world. They might have been a quirk of the complicated math used in the then still young general theory of relativity, which describes gravity. Over the years, though, evidence has accumulated that black holes are very real and even exist right here in our galaxy.

Quantum computer based on shuttling ions is built by Honeywell
A quantum charged coupled device – a type of trapped-ion quantum computer first proposed 20 years ago – has finally been fully realized by researchers at Honeywell in the US. Other researchers in the field believe the design, which offers notable advantages over other quantum computing platforms, could potentially enable quantum computers to scale to huge numbers of quantum bits (qubits) and fully realize their potential.

German Scientists Announce Traversable Wormholes Possible
Wormholes play an essential role in various science fiction films — connecting two distant points in space. However, According to physics, these tunnels in spacetime are purely theoretical. Dr. Jose Luis Blázquez-Salcedo from the University of Oldenburg supervised an international team that has now introduced a new theoretical model in the science journal Physical Review Letters that make microscopic wormholes appear less far-fetched than in earlier theories.
