The Cosmic Quandary: Stability of the Universe’s Vacuum – yTech
Summary: Contemporary scientific inquiry delves into the mysteries of the vacuum in space, uncovering its dynamic energy potential and the existential uncertainties it presents. This article examines the Casimir effect, the concept of metastable vacuum, and the implications for the universes longevity, balancing the fascination with potential cataclysm against the enduring stability observed in cosmic history.
Graviton modes observed for the first time by Chinese scientists – China Daily
Light probing chiral graviton modes in fractional quantum Hall effect liquids. [Photo/Official Wechat account of Nanjing University] Chinese scientists have for the first time observed graviton modes that are condensed-matter analogs of gravitons, a major discovery for understanding new correlated quantum physics. The research team, led by Du Lingjie from Nanjing University, spent more than three years designing and assembling an experimental apparatus that utilized resonant inelastic scattering of circularly polarized light to study low-energy collective excitations of the fractional quantum Hall liquids in a gallium arsenide quantum well.
Elusive Ghost Particles from Space May Solve A Longstanding Mystery In Quantum Physics – Inverse
Sensors buried deep in the Antarctic ice may help physicists figure out how gravity works in the quantum realm, the smallest scale of existence. A team of physicists says theyve figured out how to use a sensor-laden patch of ice near the South Pole to measure tiny changes in particles called neutrinos as they pass through space

For the 1st Time Scientists Found Experimental Evidence of Graviton-like Particle – IndianWeb2.com
Gravitons are fascinating hypothetical particles that play a pivotal role in our understanding of gravity. These are the fundamental particles that mediate the force of gravitational interaction in the realm of quantum field theory
IBM Quantum Computing Blog | Landmark IBM error correction paper on Nature cover – IBM
Today, the paper detailing those results was published as the cover story of the scientific journal Nature.1 Last year, we demonstrated that quantum computers had entered the era of utility, where they are now capable of running quantum circuits better than classical computers can. Over the next few years, we expect to find speedups over classical computing and extract business value from these systems. But there are also algorithms with mathematically proven speedups over leading classical methods that require tuning quantum circuits with hundreds of millions, to billions, of gates
Quantum computing progress: Higher temps, better error correction – Ars Technica
There's a strong consensus that tackling most useful problems with a quantum computer will require that the computer be capable of error correction. There is absolutely no consensus, however, about what technology will allow us to achieve that. A large number of companies, including major players like Microsoft, Intel, Amazon, and IBM, have all committed to different technologies to get there, while a collection of startups are exploring an even wider range of potential solutions.
Quantum computing just got hotter: 1 degree above absolute zero – The Conversation
For decades, the pursuit of quantum computing has struggled with the need for extremely low temperatures, mere fractions of a degree above absolute zero (0 Kelvin or 273.15C). Thats because the quantum phenomena that grant quantum computers their unique computational abilities can only be harnessed by isolating them from the warmth of the familiar classical world we inhabit. A single quantum bit or qubit, the equivalent of the binary zero or one bit at the heart of classical computing, requires a large refrigeration apparatus to function
3 Quantum Computing Stocks to Buy on the Dip: March 2024 – InvestorPlace
While classical computers have enjoyed tremendous capacity gains over the past few decades, its time for a paradigm shift, which brings the discussion to quantum computing stocks to buy. Here, were not just talking about shifting gears but moving from a race car to a rocket ship
First Business PCs to Protect Firmware Against Quantum Computer Hacks – Manufacturing.net
The potential introduction of quantum computerscapable of breaking asymmetric cryptography could place the entire digital world at risk, and this risk is becoming increasingly plausible every day.This led HP tounveilPCs designed to protect firmware against quantum computer attacks. Features include: Research showsthat 27 percent of experts think there is a 50 percent likelihood of a cryptographically relevant quantum computer (CRQC) by 2033. When that day comes, thesecurity of existing digital signatures on firmware and software will be in question.
