Time travel has long captured the human imagination, from its appearances in science fiction fantasies to its profound implications in modern theoretical physics. Now, a recent study by Dr. Lorenzo Gavassino, a theoretical and mathematical physicist at Vanderbilt University, delves into the enigmatic nature of time travel involving time loops to examine their profound implications for quantum mechanics, entropy, and human experience. Dr. Gavassino’s findings, published in Classical and Quantum Gravity, present a strikingly different picture of time travel. They reveal that traveling through such time loops would prevent many classical time travel paradoxes, including the infamous “grandfather paradox.” “It...

Consciousness defines what it means to be human, yet its mechanisms remain elusive. Scientists know that anesthetics can “turn off” consciousness, but how they achieve this is still unclear. Two dominant theories attempt to explain consciousness: the Integrated Information Theory (IIT), which posits that consciousness arises from the integration of information, and the Global Workspace Theory (GWT), which suggests it emerges from the exchange of information across different parts of the brain. In 1989, British mathematician and Nobel laureate Roger Penrose proposed an unconventional hypothesis linking consciousness to quantum entanglement. He argued that the human mind could solve problems that...

Scientists report the first known observation of a variety of quasiparticle that exhibits a very peculiar behavior: it appears to have mass, but only while moving in one direction. Scientists at Pennsylvania State University recently succeeded in detecting the unusual quasiparticle while conducting studies involving a semi-metallic crystalline material. Known as a semi-Dirac fermion, this unique formation of particles was first theorized more than a decade ago, but until now had never been directly observed. The discovery potentially paves the way toward future advances in a range of emerging technologies that include power storage and novel forms of sensor technologies....

The field of quantum computing has taken a giant leap forward with the development of the Willow chip. Over a decade in the making, this achievement stems from a vision to harness the fundamental principles of quantum mechanics for scientific discovery, problem-solving, and transformative applications. The Willow chip represents a major step toward realizing large-scale, commercially useful quantum computers.A critical hurdle in quantum computing has been error correction. Qubits, the foundational units of quantum computation, are notoriously fragile and prone to interacting with their environment, leading to errors. These errors increase with the number of qubits, often rendering the system...

Quantum entanglement in top quarks has been demonstrated, according to physicists at CERN who say the discovery offers new insights into the behavior of fundamental particles and their interactions at distances that cannot be attained by light-speed communication. The research, led by University of Rochester professor Regina Demina, extends the phenomenon known as “spooky action at a distance” to the heaviest particles recognized by physicists and offers important new insights into high-energy quantum mechanics. Initially discovered almost three decades ago, top quarks are the most massive elementary particles that have been observed. The mass of these unique particles originates from...

Scientists say they have created an experimental new high-tech window coating that works similarly to polarized lenses on sunglasses by allowing all of the visible light through while also reflecting unwanted heat. If added to existing buildings and car windows, the new coating could reduce internal temperatures in hotter climates without sacrificing any of the visible light while also reducing energy usage for indoor air conditioning by as much as 30%. The new coating was developed by researchers from Notre Dame University who were looking for a cheap yet viable way to reduce the use of air conditioning in cars...

The job of physicists is to worry about numbers, but one number has perplexed physicists for more than a century. That number is 0.00729735256—approximately 1/137. This is the fine-structure constant. It appears everywhere in the equations of quantum physics. The fine-structure constant, designated by the Greek letter alpha (α), is one of the many constants of nature that power our laws of physics, like the speed of light, the gravitational constant, or Planck’s constant. These constants can have different values depending upon which system of units are used to express them. For instance, the speed of light in vacuum is...

Iran's Rear Admiral Habibollah Sayyari, Coordinating Deputy of the Islamic Republic's Army (and former Commander of the Navy), alongside Imam Khomeini University of Marine Sciences and Technologies (RA), has unveiled what it is calling the "first product of the quantum processing algorithm. Essentially, a newly-designed quantum computing board that is apparently already being used by the Iranian Military to "counter navigation deception in detecting surface vessels using the quantum algorithms." And with the hardware showcased as part of a photo-op, it didn't take long for someone to notice that the hardware being shown is an off-the-shelf ARM-based FPGA SoC development...

Quantum machine - Inside the 30-meter tube. (ETH Zurich/Daniel Winkler) Albert Einstein wasn't entirely convinced about quantum mechanics, suggesting our understanding of it was incomplete. In particular, Einstein took issue with entanglement, the notion that a particle could be affected by another particle that wasn't close by. Experiments since have shown that quantum entanglement is indeed possible and that two entangled particles can be connected over a distance. Now a new experiment further confirms it, and in a way we haven't seen before. In the new experiment, scientists used a 30-meter-long tube cooled to close to absolute zero to run...

The germanium-tin processor was fabricated at the Helmholtz Nano Facility, the Helmholtz Association's central technology platform for the manufacturing of nanostructures and circuits. Credit: Forschungszentrum Juelich Scientists at Forschungszentrum Jülich have fabricated a new type of transistor from a germanium–tin alloy that has several advantages over conventional switching elements. Charge carriers can move faster in the material than in silicon or germanium, which enables lower voltages in operation. The transistor thus appears to be a promising candidate for future low-power, high-performance chips, and possibly also for the development of future of quantum computers. Over the past 70 years, the number...

A group of Chinese researchers have just published a paper claiming that they can—although they have not yet done so—break 2048-bit RSA. This is something to take seriously. It might not be correct, but it’s not obviously wrong. We have long known from Shor’s algorithm that factoring with a quantum computer is easy. But it takes a big quantum computer, on the orders of millions of qbits, to factor anything resembling the key sizes we use today. What the researchers have done is combine classical lattice reduction factoring techniques with a quantum approximate optimization algorithm. This means that they only...

1. A cat can be dead and alive Obviously, a cat is nothing like an individual photon in a controlled lab environment, it is much bigger and more complex. Any coherence that the trillions upon trillions of atoms that make up the cat might have with each other is extremely short-lived. This does not mean that quantum coherence is impossible in biological systems, just that it generally won't apply to big creatures such as cats or a human. 2. Simple analogies can explain entanglement Quantum particles are just mysteriously correlated in ways we can't describe with everyday logic or language...

“In some pockets of space, far beyond the limits of our observations,” wrote cosmologist Dan Hooper at the University of Chicago in an email to The Daily Galaxy, referring to the theory of eternal inflation and the inflationary multiverse: “the laws of physics could be very different from those we find in our local universe. Different forms of matter could exist, which experience different kinds of forces. In this sense, what we call ‘the laws of physics’, instead of being a universal fact of nature, could be an environmental fact, which varies from place to place, or from time to...

By shining a laser pulse sequence inspired by the Fibonacci numbers at atoms inside a quantum computer, physicists have created a remarkable, never-before-seen phase of matter. The phase has the benefits of two time dimensions despite there still being only one singular flow of time... This mind-bending property offers a sought-after benefit: Information stored in the phase is far more protected against errors than with alternative setups currently used in quantum computers. As a result, the information can exist without getting garbled for much longer, an important milestone for making quantum computing viable, says study lead author Philipp Dumitrescu. The...
