The universe appears to be fine-tuned for life to evolve.

The breakthrough material, a blend of aminoferrocene and graphene, has magnetic properties 100 times stronger than pure iron, eliminating the reliance on rare Earth materials for magnet construction.

Particle accelerators are crucial tools in a wide variety of areas in industry, research and the medical sector. The space these machines require ranges from a few square meters to large research centers. Using lasers to accelerate electrons within a photonic nanostructure constitutes a microscopic alternative with the potential of generating significantly lower costs and making devices considerably less bulky. Until now, no substantial energy gains were demonstrated. In other words, it has not been shown that electrons really have increased in speed significantly. Two teams of laser physicists have just succeeded in demonstrating a...

To pry into the private lives of objects in the microscopic domain (and beyond), scientists often rely on extremely bright sources of light.

Quantum computers may still be years away, but it’s prudent that end-to-end encryption providers are ramping up defences

We introduce a hybrid digital signature scheme based on two building blocks: a classically-secure scheme, ECDSA, and a post-quantum secure one, Dilithium. Our hybrid scheme maintains the guarantees of each underlying building block even if the other one is broken, thus being resistant to classical and quantum attacks.

The expansion of the universe could be a mirage, a potentially controversial new study suggests. This rethinking of the cosmos also suggests solutions for the puzzles of dark energy and dark matter, which scientists believe account for around 95% of the universe's total energy and matter but remain shrouded in mystery.

A new experiment uses superconducting qubits to demonstrate that quantum mechanics violates what's called local realism by allowing two objects to behave as a single quantum system no matter how large the separation between them. The experiment wasn't the first to show that local realism isn't how the Universe works—it's not even the first to do so with qubits.

We don’t know when. We don’t know who will get there first. But Q-day will happen — and it will change the world as we know it.

Scientists were able to keep a qubit in its ideal state for twice as long as normal. Along the way, they demonstrated the practicality of quantum error correction (QEC), a process that keeps quantum information intact for longer by introducing room for redundancy and error removal.

An Austrian and Spanish team demonstrated that a process can be ‘rewound’ to restore the components of an atom to their previous state.

In an era of quantum computing "arms race", it is time to transition to quantum-safe systems.

Ajarring divide cleaves modern physics. On one side lies quantum theory, which portrays subatomic particles as probabilistic waves. On the other lies general relativity, Einstein’s theory that space and time can bend, causing gravity. For 90 years, physicists have sought a reconciliation, a more fundamental description of reality that encompasses both quantum mechanics and gravity. But the quest has run up against thorny paradoxes.

Researchers at the Kastler Brossel Laboratory in Paris have succeeded in building the first converter between the two different types of quantum-bit encodings—an equivalent to converters for classical information, but targeted to different types of quantum data. This high-quality rewriting of information shows the way towards bridging the gap between the many different platforms competing in the race for quantum computing and may enable the interconnectivity of future networks.

If life is common in our Universe, and we have every reason to suspect it is, why do we not see evidence of it everywhere? This is the essence of the Fermi Paradox, a question that has plagued astronomers and cosmologists almost since the birth of modern...

Researchers have transferred 'quantum' information between computer chips at record speeds and accuracy.

Physicists have invented a new type of analog quantum computer that can tackle hard physics problems that the most powerful digital supercomputers cannot solve.

A concept called “quantum entanglement” suggests the fabric of the universe is more interconnected than we think. And it also suggests we have the wrong idea about reality.
