Simulating a critical point in quark gluon fluid

Posted by in categories: particle physics, quantum physics

Scientists are conducting experiments in search of evidence of a possible critical point in the Quantum Chromodynamics phase diagram. Quantum chromodynamics describes how the strong force binds quarks and antiquarks together to form protons, neutrons, and other particles known as hadrons.

Team studies the emergence of fluctuating hydrodynamics in chaotic quantum systems

Posted by in categories: particle physics, quantum physics

Researchers at Ludwig-Maximilians-Universität, Max-Planck-Institut für Quantenoptik, Munich Center for Quantum Science and Technology (MCQST) and the University of Massachusetts recently carried out a study investigating the equilibrium fluctuations in large quantum systems. Their paper, published in Nature Physics, outlines the results of large-scale quantum simulations performed using a quantum gas microscope, an experimental tool used to image and manipulate individual atoms in ultracold atomic gases.

Stephen Hawking’s black hole radiation paradox could finally be solved — if black holes aren’t what they seem

Posted by in categories: cosmology, quantum physics, singularity

New research suggests that black holes may actually be “frozen stars,” bizarre quantum objects that lack a singularity and an event horizon, potentially solving some of the biggest paradoxes in black hole physics.

Phase transition in magic with random quantum circuits

Posted by in categories: computing, quantum physics

In quantum computing, “magic” refers to a special quality of quantum states that is essential for enabling powerful, fault-tolerant quantum computations.


Coherent noise affecting a random error correcting code is now shown to produce aion between phases that accumulate and destroy magic.

Physicists use quantum correlations of photon pairs to hide images from standard cameras

Posted by in categories: electronics, quantum physics

What if you could hide an image in plain sight—so well that even the most advanced cameras couldn’t detect it? Imagine encoding visual information using the properties of quantum optics, rendering it invisible to normal imaging technology.

Ephos raises $8.5M to transform quantum computing and AI with its glass-based quantum photonic chips

Posted by in categories: quantum physics, robotics/AI

A Milan-based deep tech startup, Ephos, raised $8.5M in a seed round led by Starlight Ventures to accelerate the development of its glass-based quantum photonic chips. The company aims to transform not just quantum computing and AI but also the broader computational infrastructure of the future.

Other participants included Collaborative Fund, Exor Ventures, 2100 Ventures, and Unruly Capital. The round also attracted angel investors such as Joe Zadeh, former Vice President at Airbnb; Diego Piacentini, former Senior Vice President at Amazon; and Simone Severini, General Manager of Quantum Technologies at Amazon Web Services.

In addition to private investment, Ephos received funding from the European Innovation Council (EIC) and €450,000 in non-dilutive financing from NATO’s Defence Innovation Accelerator (DIANA).

Thermodynamics of frozen stars

Posted by in categories: cosmology, information science, quantum physics

New study suggests that black holes may not be the featureless, structureless entities that Einstein’s general theory of relativity predicts them to be.


The frozen star is a recent proposal for a nonsingular solution of Einstein’s equations that describes an ultracompact object which closely resembles a black hole from an external perspective. The frozen star is also meant to be an alternative, classical description of an earlier proposal, the highly quantum polymer model. Here, we show that the thermodynamic properties of frozen stars closely resemble those of black holes: frozen stars radiate thermally, with a temperature and an entropy that are perturbatively close to those of black holes of the same mass. Their entropy is calculated using the Euclidean-action method of Gibbons and Hawking. We then discuss their dynamical formation by estimating the probability for a collapsing shell of “normal’’ matter to transition, quantum mechanically, into a frozen star.
