Einstein’s gravity and quantum mechanics united at last?

Posted by in category: quantum physics

“Our task,” Fedorov wrote, “is to make nature, the blind force of nature, into an instrument of universal resuscitation and to become a union of immortal beings.”

Fedorov’s writing never turned mainstream, but it did spawn a short-lived, visionary philosophical movement known as Cosmism. Materialized during the Industrial Revolution — a time of unprecedented societal change — the movement generally sought to redefine mankind’s relationship with technology and progress, with the ultimate goal of regulating the forces of nature so that humanity could achieve unity and immortality. The movement offered a more spiritual alternative to both futurism and communism.

Although the latter annihilated Cosmism before it had a chance to mature, its maxims have acquired new relevancy in the age of Big Tech. The following interview with Boris Groys, a distinguished professor of Russian and Slavic studies at New York University and editor of the new book Russian Cosmism, reveals why.

Physicists Successfully Create Holographic Wormhole with Quantum Computer

Posted by in categories: computing, cosmology, holograms, quantum physics

In an experiment reported in the journal Nature, physicists have achieved a remarkable feat by creating the world’s first quantum holographic wormhole. The experiment delves into the profound connection between quantum information and space-time, challenging traditional theories and shedding light on the complex relationship between quantum mechanics and general relativity.

The team, led by Maria Spiropulu from the California Institute of Technology, utilized Google’s quantum computer, Sycamore, to implement the groundbreaking “wormhole teleportation protocol.” This quantum gravity experiment on a chip surpassed competitors using IBM and Quantinuum’s quantum computers, marking a significant leap in the exploration of quantum phenomena.

The holographic wormhole emerged as a hologram from manipulated quantum bits, or “qubits,” stored in minute superconducting circuits. This achievement brings us closer to realizing a tunnel, theorized by Albert Einstein and Nathan Rosen in 1935, that traverses an extra dimension of space. The team successfully transmitted information through this quantum tunnel, further validating the experiment’s success.

Qubits are notoriously prone to failure — but building them from a single laser pulse may change this

Posted by in category: quantum physics

Qubits are normally made from superconducting metals and need to be cooled to near absolute zero to avoid collapsing. But scientists just built an error-free “logical qubit” from a single laser pulse — and it works at room temperature.

A new phase of matter: Physicists achieve first demonstration of non-Abelian anyons in a quantum processor

Posted by in categories: particle physics, quantum physics

Our physical, 3D world consists of just two types of particles: bosons, which include light and the famous Higgs boson; and fermions—the protons, neutrons, and electrons that comprise all the “stuff,” present company included.

Theoretical physicists like Ashvin Vishwanath, Harvard’s George Vasmer Leverett Professor of Physics, don’t like to limit themselves to just our world, though. In a 2D setting, for instance, all kinds of new particles and states of matter would become possible.

Vishwanath’s team used a powerful machine called a to make, for the first time, a brand-new phase of matter called non-Abelian topological order. Previously recognized in theory only, the team demonstrated synthesis and control of exotic particles called non-Abelian anyons, which are neither bosons nor fermions, but something in between.

Harnessing the Power of Neutrality: Comparing Neutral-Atom Quantum Computing With Other Modalities

Posted by in categories: computing, particle physics, quantum physics

How Does The Neutral Atom Approach Compare

The neutral atom approach is a well-known and extensively investigated approach to quantum computing. The approach offers numerous advantages, especially in terms of scalability, expense, error mitigation, error correction, coherence, and simplicity.

Neutral atom quantum computing utilizes individual atoms, typically alkali atoms like rubidium or cesium, suspended and isolated in a vacuum and manipulated using precisely targeted laser beams. These atoms are not ionized, meaning they retain all their electrons and do not carry an electric charge, which distinguishes them from trapped ion approaches. The quantum states of these neutral atoms, such as their energy levels or the orientation of their spins, serve as the basis for qubits. By employing optical tweezers—focused laser beams that trap and hold the atoms in place—arrays of atoms can be arranged in customizable patterns, allowing for the encoding and manipulation of quantum information.
