A new kind of black hole analog could tell us a thing or two about an elusive radiation theoretically emitted by the real thing.

Using a chain of atoms in single-file to simulate the event horizon of a black hole, a team of physicists has observed the equivalent of what we call Hawking radiation – particles born from disturbances in the quantum fluctuations caused by the black hole’s break in spacetime.

This, they say, could help resolve the tension between two currently irreconcilable frameworks for describing the Universe: the general theory of relativity, which describes the behavior of gravity as a continuous field known as spacetime; and quantum mechanics, which describes the behavior of discrete particles using the mathematics of probability.

Hypothetical bridges connecting distant regions of space (and time) could more or less look like garden variety black holes, meaning it’s possible these mythical beasts of physics have already been seen.

Thankfully however, if a new model proposed by a small team of physicists from Sofia University in Bulgaria is accurate, there could still be a way to tell them apart.

Play around with Einstein’s general theory of relativity long enough, it’s possible to show how the spacetime background of the Universe can form not only deep gravitational pits where nothing escapes – it can form impossible mountain peaks which can’t be climbed.

Frank Close tells the human story of how we solved The Infinity Puzzle – once the bane of physics

INFINITY. In mathematics, it’s a curiosity. In physics, it’s a disease. It reared its head back in the 1940s, with quantum electrodynamics (QED), the theory of electromagnetism.

A group of scientists from Aalto University, IQM Quantum Computers, and VTT Technical Research Center have discovered a new superconducting qubit, the unimon, to increase the accuracy of quantum computations. The team has achieved the first quantum logic gates with unimons at 99.9% fidelity—a major milestone on the quest to build commercially useful quantum computers. This research was just published in the journal Nature Communications.

Of all the different approaches to build useful quantum computers, are in the lead. However, the designs and techniques currently used do not yet provide high enough performance for practical applications. In this noisy intermediate-scale quantum (NISQ) era, the complexity of the implementable quantum computations is mostly limited by errors in single-and two-qubit quantum gates. The quantum computations need to become more accurate to be useful.

“Our aim is to build quantum computers which deliver an advantage in solving real-world problems. Our announcement today is an important milestone for IQM, and a significant achievement to build better superconducting quantum computers,” said Professor Mikko Möttönen, joint Professor of Quantum Technology at Aalto University and VTT, and also a Co-Founder and Chief Scientist at IQM Quantum Computers, who was leading the research.

The patients had some, although severely diminished, visual function during the day, however, at night they were essentially blind, with light sensitivity 10,000–100,000 times less than normal.

According to researchers at the Scheie Eye Institute at the Perelman School of Medicine at the University of Pennsylvania, adults with a genetic form of childhood-onset blindness experienced remarkable recoveries of night vision within days of receiving an experimental gene therapy.

The patients had Leber Congenital Amaurosis (LCA), a congenital blindness caused by GUCY2D gene mutations. The findings were published in the journal iScience. The researchers administered AAV gene therapy, which contains the DNA.
