Why More Physicists Are Starting to Think Space and Time Are ‘Illusions’
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.

Physicists have used entanglement to 'stretch' the uncertainty principle, improving quantum measurements
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.

What are companies doing with D-Wave’s quantum hardware?
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: Searching for the universal rules of physics
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.

IBM accelerates quantum computing with 433-qubit processor, eyes even more power
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.

Physicists made the most precise measurement ever of a single particle
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...

Does Quantum Entanglement Allow for Faster-Than-Light Communication?
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.

Scientific experiment creates ‘two dimensional’ time
Scientists have created a new phase of matter, in which time has two dimensions. The creation of an “extra” dimension in time could change the way we think about matter as well as helping build quantum computers that could themselves change the world, according to the researchers who found it.

'Time crystals' work around laws of physics to offer new era of quantum computing
The connecting of two "time crystals" in a superfluid of helium-3 barely one-ten-thousandth of a degree above absolute zero could be a huge step toward a new kind of quantum computer. Time crystals are bizarre structures of atoms, the existence of which was only predicted as recently as 2012, with experimental proof following a few years later. In a normal crystal, such as diamond or salt, the atoms are arranged in a regularly repeating spatial pattern — a lattice or similar framework. And like most materials, when the atoms are in their ground state — their lowest possible energy level — they stop jiggling.
