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.

Examining microscopic quantum objects is exceedingly tricky, because their properties are connected to each other. But there could be a new method to measure them as accurately as possible.

While many companies are now offering access to general-purpose quantum computers, they're not currently being used to solve any real-world problems, as they're held back by issues with qubit count and quality. Most of their users are either running research projects or simply gaining experience with programming on the systems in the expectation that a future computer will be useful.

The Theory of Everything is an overarching hypothetical framework that would explain the physics of the entire universe in a single equation. But unifying theories that define the large-scale cosmological structure of the universe with those that describe the minuscule quantum world of the subatomic particles has been a challenge for over a century.

Physicists have long struggled to explain why the Universe started out with conditions suitable for life to evolve.

Some of today’s quantum physicists are tinkering with an esoteric phase of matter that seems to disobey some of our laws of physics. What exactly is a time crystal?

A team of physicists has entangled three photons over a considerable distance, which could lead to more powerful quantum cryptography.

Quantum mechanics, the theory which rules the microworld of atoms and particles, certainly has the X factor.

With conventional computing silicon, computing performance is often a function of clock speed and thread processing capabilities. For quantum computing, to date, the qubit has been the defining metric and it’s a number that keeps getting bigger. A year ago, IBM announced that it had developed a127-qubit processor codenamed Eagle. Today at the IBM Quantum 2022 Summit, Big Blue announced a four- fold increase with its new Osprey Quantum processor, which can deliver 433 qubits.

A new assessment of the electron is the most precise measurement of a particle ever taken, at a precision of 1.3 parts in 10 trillion, and could tell us about new physics happening at the smallest scales. The electron’s magnetic moment is a quantum property related to magnetism and is predicted by the standard model, our current understanding of how the basic building blocks of the universe interact. But the standard model is unable to explain certain real-world observations...

Quantum entanglement allows particles to affect one another faster than the speed of light. So does this mean we could one day build a device to exploit this and enable superluminal communication? A popular trope in sci-fi for sure, but today let's look at the science.

Few things in the Universe keep the beat as reliably as an atom's pulse.

Mysterious “islands” help to explain what happens to information that falls into a black hole
