While entangled photons hold incredible promise for quantum computing and communications, they have a major inherent disadvantage. After one use, they simply disappear.

In a new study, Northwestern University physicists propose a new strategy to maintain communications in a constantly changing, unpredictable quantum network. By rebuilding these disappearing connections, the researchers found the network eventually settles into a stable—albeit different—state.

The key resides in adding a sufficient number of connections to ensure the network continues to function, the researchers found. Adding too many connections comes with a high cost, overburdening the resources. But adding too few connections results in a fragmented network that cannot satisfy the user demand.

Scientists at the National Institute of Standards and Technology (NIST) have created a new thermometer using atoms boosted to such high energy levels that they are a thousand times larger than normal. By monitoring how these giant “Rydberg” atoms interact with heat in their environment, researchers can measure temperature with remarkable accuracy. The thermometer’s sensitivity could improve temperature measurements in fields ranging from quantum research to industrial manufacturing.

Unlike traditional thermometers, a Rydberg doesn’t need to be first adjusted or calibrated at the factory because it relies inherently on the basic principles of quantum physics. These fundamental quantum principles yield that are also directly traceable to international standards.

“We’re essentially creating a thermometer that can provide accurate temperature readings without the usual calibrations that current thermometers require,” said NIST postdoctoral researcher Noah Schlossberger.

Quantum entanglement contains important information about quantum systems, but its calculation is challenging. Here the authors develop a quantum Monte Carlo technique for full tomography on microscopic subregions of a system, enabling extraction of multipartite quantum entanglement in large scale models.

In a groundbreaking study published in Nature, researchers from the University of British Columbia, the University of Washington, and Johns Hopkins University have identified a new class of quantum states in a specially engineered graphene structure. They found topological electronic crystals in twisted bilayer–tilayer graphene, made by stacking and twisting two-dimensional graphene layers.

Graphene, composed of carbon atoms arranged in a honeycomb structure, has unique electrical properties due to the way electrons hop between the carbon atoms.

Prof. Joshua Folk from UBC explains that stacking two graphene flakes with a slight twist creates a geometric interference effect known as a moiré pattern, changing how electrons move, slowing them down, and twisting their motion.

Though the notion of the supernatural has captivated humanity across continents and centuries, the most compelling path to explaining such mysteries may reside in the fundamental operations of nature itself. The premise that there is no realm beyond the natural order underpins the hypothesis that any genuine paranormal or spiritual phenomenon, if it exists, must be quantum in character. On the surface, this sounds audacious: quantum theory is already widely deemed one of the most counterintuitive scientific frameworks, replete with superpositions, entanglement, and the undeniable role of altering reality via measurement. Yet these very features seem to provide the most plausible scaffolding upon which experiences such as extrasensory perception (ESP), clairvoyance, telepathy, contact with disembodied spirits, psychokinesis, reincarnation, or even a continuation of existence in an afterlife, could be built.

Those who have conducted painstaking investigations into alleged parapsychological happenings often begin with the simplest question: Can these events be rigorously documented? The Princeton Engineering Anomalies Research (PEAR) program endeavored to place mind–machine interactions under stringent laboratory conditions for more than two decades, testing whether human intention could alter random-event generators. Their experimental data reported “small but consistent deviations from expected outputs” (Jahn & Dunne, 1987, p. 45). Mainstream critics rightly pointed to the difficulty of reconciling such deviations with known physics. However, these critics also noted that if the data were taken at face value, the underlying mechanism could only be teased out by exploring deeper layers of reality that engage both mind and matter — precisely the realm where quantum theory holds sway.

As we delve further into the annals of psychical research, Dean Radin’s contributions provide an illuminating guide. In The Conscious Universe: The Scientific Truth of Psychic Phenomena, Radin (1997) summarizes meta-analyses across thousands of trials testing telepathy, clairvoyance, and precognition. He concludes that “if psi is real, then we will see small but systematic deviations from chance expectations across many studies” (p. 136). Over and over, this is what he reports. Conventional interpretations falter, but an appeal to quantum processes — whose probabilistic nature might be subtly influenced by consciousness — begins to feel less like arcane speculation and more like a coherent, if daring, hypothesis.

Quantum entanglement—a phenomenon where particles are mysteriously linked no matter how far apart they are—presents a long-standing challenge in the physical world, particularly in understanding its behavior within complex quantum systems.

A research team from the Department of Physics at The University of Hong Kong (HKU) and their collaborators have recently developed a novel algorithm in quantum physics known as ‘entanglement microscopy’ that enables visualization and mapping of this extraordinary phenomenon at a microscopic scale.

By zooming in on the intricate interactions of entangled particles, one can uncover the hidden structures of quantum matter, revealing insights that could transform technology and deepen the understanding of the universe.

The Search for Quantum Gravity

Physics faces a profound crisis as it struggles to unify two foundational theories: general relativity and quantum mechanics. While general relativity explains gravity and large-scale phenomena, quantum mechanics governs the microscopic world of particles. Despite their individual successes, these theories conflict, prompting the need for a unified framework known as quantum gravity.

One promising approach is string theory, which posits that particles are actually vibrating strings in up to 11 dimensions. However, its lack of testable predictions has spurred alternative ideas, such as loop quantum gravity. This theory envisions space and time as a network of minuscule loops, challenging the notion of time as a fundamental construct. Remarkably, loop quantum gravity suggests time might not exist at all.

Researchers leverage their understanding of molecular motors to improve nanoscale.

The term “nanoscale” refers to dimensions that are measured in nanometers (nm), with one nanometer equaling one-billionth of a meter. This scale encompasses sizes from approximately 1 to 100 nanometers, where unique physical, chemical, and biological properties emerge that are not present in bulk materials. At the nanoscale, materials exhibit phenomena such as quantum effects and increased surface area to volume ratios, which can significantly alter their optical, electrical, and magnetic behaviors. These characteristics make nanoscale materials highly valuable for a wide range of applications, including electronics, medicine, and materials science.
