According to a recent study from the University of Helsinki, published in the journal Physical Review Letters, a vortex of a superfluid that has been quantized four times has three ways of dividing, depending on the temperature.
The fluid transforms into a superfluid near the absolute zero point of temperature (approximately −273°C). Internal resisting forces, such as friction, disappear. At this point, the behavior of the fluid can no longer be described using classical mechanics; instead, quantum physics must be applied.
When a superfluid is spun, the resulting rotation should never slow down because superfluids have no viscosity or friction. This has been experimented with at the atomic level using helium at very slow rotation, and it was observed that the superfluid, however, eventually halted.
A collaborative project has made a breakthrough in enhancing the speed and resolution of widefield quantum sensing, leading to new opportunities in scientific research and practical applications.
By collaborating with scientists from Mainland China and Germany, the team has successfully developed a quantum sensing technology using a neuromorphic vision sensor, which is designed to mimic the human vision system. This sensor is capable of encoding changes in fluorescence intensity into spikes during optically detected magnetic resonance (ODMR) measurements.
The key advantage of this approach is that it results in highly compressed data volumes and reduced latency, making the system more efficient than traditional methods. This breakthrough in quantum sensing holds potential for various applications in fields such as monitoring dynamic processes in biological systems.
Quantum computing engineers at UNSW Sydney have shown they can encode quantum information—the special data in a quantum computer—in four unique ways within a single atom, inside a silicon chip.
The feat could alleviate some of the challenges in operating tens of millions of quantum computing units in just a few square millimeters of a silicon quantum computer chip.
In a paper published in Nature Communications, the engineers describe how they used the 16 quantum ‘states’ of an antimony atom to encode quantum information.
Last year, a Quantinuum-led team of scientists announced that they were able to realize and control a state of matter known as non-Abelian topological order within a quantum processor. The team published their results in the pre-print server ArXiv, outlining how they accomplished what many experts considered a far-off advance — if possible at all – and what the scientists hoped could be an advance toward revolutionizing the way we approach quantum computing.
That advance has now been officially peer reviewed in Nature, marking another important step in the scientific process – and maybe even a significant step in the quest for fault-tolerant quantum computers, a quantum device that could handle operations with unprecedented accuracy and efficiency.
“Our key finding is that non-Abelian topological orders can experimentally be prepared with high fidelities on par with Abelian states like the surface code,” the team writes. “Non-Abelian states are among the most intricately entangled quantum states theoretically known to exist, and carry promise for new types of quantum information processing. Their realization evidences the rapid development of quantum devices and opens several new questions.”
We present a new route to ergodicity breaking via Hilbert space fragmentation that displays an unprecedented level of robustness. Our construction relies on a single emergent (prethermal) conservation law. In the limit when the conservation law is exact, we prove the emergence of Hilbert space fragmentation with an exponential number of frozen configurations. These configurations are low-entanglement states in the middle of the energy spectrum and therefore constitute examples of quantum many-body scars. We further prove that every frozen configuration is absolutely stable to arbitrary perturbations, to all finite orders in perturbation theory.

Ultimate fact presents top 15 Weapons Of The Future Will Blow Your Mind. We’ve come a long way since sticks and stones, and it’s almost inconceivable that only a few hundred years ago, Man was still waging war with bows, arrows, cannons, and muskets. Modern militaries are constantly in the process of developing new weapons, some of which will definitely make some mouths drop. We thought it would be fun to take a closer look at the most amazing offensive and defensive weapons currently in the works. Autonomous weapons. These are robotic vehicles, under development, that search and destroy enemy troops and equipment on the ground or in the air, without risk to friendly troops – theoretically. Onboard computers interpret sensor data to identify and target hostile forces with built-in weapons. Robots may query human controllers at remote sites for the go-ahead to fire, and friendly forces may carry transponders that identify them as “friends” High-energy lasers. These are powerful energy beams that travel through air or space in straight lines. They travel at the speed of light and can strike over distances of thousands of kilometres. Large mirrors focus powerful laser beams onto a small spot on the target. Space-based weapons. Space is the ultimate high ground, so weapons in orbit would have the ability to see and zap anything on the ground, in the air, or nearby in space. The main mission of space-based weapons would be to defend against ballistic missiles fired at targets on Earth. Hypersonic aircraft. Launched from a standard runway, a hypersonic aircraft could fly faster than Mach 5 to strike anywhere in the world within two hours. It would also have enough thrust to deliver a satellite to low-Earth orbit. To get off the ground from a runway, a hypersonic plane would either hitch a ride on a conventional plane, or have its own conventional jet engine. Active Denial System. Millimetre-wave or microwave beams supposedly make people flee without injuring them. They might typically be powered by a generator fitted to a Humvee, in crowd control situations. A 2-metre antenna and mobile generator produce and aim a beam of 95-gigahertz (3-millimetre) radiation. Nuclear missiles. Nuclear missiles are able to deliver unmatched destructive power anywhere in the world, making them the ultimate level of military power. One or more nuclear warheads are mounted on a ballistic missile, and launched vertically. Stun guns (Tasers) Tasers disable people with bursts of high-voltage electricity, allowing police to subdue them without lasting injury. A special gun fires darts on wires. These deliver a pulse of electricity that temporarily disrupts control of voluntary muscles. E-bombs. A rapid increase in electromagnetic field strength during a pulse, induces surges of electric current in conductors. This burns out electrical equipment – semiconductor chips are particularly vulnerable. Layered missile defence. Layered missile defence offers the best chance to shoot down attacking ballistic missiles. Multiple anti-missile systems are deployed to target ballistic missiles during different stages of the attacking missile’s flight: Each phase, or layer, of defence increases the chance of successful destruction of the missile. Information warfare. This technique interferes with the flow of information vital to enemy operations, while defending friendly channels of communication. Information warfare specifically targets communication networks and computers. ‘Hyper Stealth’ or ‘Quantum Stealth’ Using naturally occurring metamaterials, scientists have been designing lightwave-bending materials that can greatly reduce the thermal and visible signatures of a target. Electromagnetic Rail Guns. EM rail gun launchers use a magnetic field rather than chemical propellants (e.g., gunpowder or fuel) to thrust a projectile at long range and at velocities of 4,500 mph to 5,600 mph. nautical miles using 32 megajoules. The extended velocity and range of EM rail guns provides several benefits both in offensive and defensive terms, from precision strikes that can counter even the most advanced area defense systems to air defense against incoming targets. Space Weapons. Despite international pressure against the weaponization of space, major countries continue to explore technologies that would turn the sky above us into the next battleground. Hypersonic Cruise Missiles and ‘Prompt Global Strike’ Had hypersonic cruise missiles existed in the mid-1990s, the U.S. might have rid itself of Al Qaeda leader Osama bin Laden much earlier than it did, and would have accomplished the feat in Afghanistan rather than in Pakistan. Sentient’ Unmanned Vehicles. Perhaps the single-most important development in the defense industry in the past decade is the emergence of unmanned vehicles. Among this which one seems most terrible to you let us know in the comment section. #UltimateFact #Weaon #Facts
