Researchers at the University of Science and Technology of China have managed to entangle a record 51 qubits. More importantly, the qubits weren’t just entangled in pairs, but as a single system, a re.
Gero, an AI-driven biotech focused on aging and longevity, has demonstrated the feasibility of applying quantum computing for drug design and generative chemistry, which now offers significant promise for the future of healthcare. The research, published in Scientific Reports, outlines how a hybrid quantum-classical machine-learning model was used to interface between classical and quantum computational devices with the goal of generating novel chemical structures for potential drugs—an industry first.
The research paper follows in the wake of recent advancements from Gero, which sparked vigorous discussion among longevity experts in the scientific community when a story was published in Popular Mechanics that asserted humans can stop—but not fully reverse—aging. Earlier this year, Gero announced a target discovery deal with Pfizer, whereby Gero’s machine-learning technology platform is being applied to discover potential therapeutic targets for fibrotic diseases using large-scale human data.
In this new line of research, the team explored whether a hybrid generative AI system—a deep neural network working in conjunction with commercially available quantum hardware—could suggest unique chemical structures that are synthetically feasible and possess drug-like properties.
Theoretical physicists have a lot in common with lawyers. Both spend a lot of time looking for loopholes and inconsistencies in the rules that might be exploited somehow.
Valeri P. Frolov and Andrei Zelnikov from the University of Alberta in Canada and Pavel Krtouš from Charles University in Prague probably couldn’t get you out of a traffic fine, but they may have uncovered enough wiggle room in the laws of physics to send you back in time to make sure you didn’t speed through that school zone in the first place.
Shortcuts through spacetime known as wormholes aren’t recognized features of the cosmos. But for the better part of a century, scientists have wondered if the weft and warp instructed by relativity prescribe ways for quantum ripples – or even entire particles – to break free of their locality.
Are back holes related to dark matter? Do the observations of black holes by LIGO hint at a signature of quantum gravity? Can we find evidence of black holes from a previous universe?
In 2019 second place in the Buchalter Cosmology Prize was awarded to two of the speakers you will see in this film which explores some of the above themes. We filmed this at the Loop Quantum Gravity Conference in 2019 and plan to make a follow up film exploring the latest ideas in the field.

As scientists explore the quantum world, the known number of phases of matter continues to grow. The newest addition to the list is a chiral bose-liquid state.
Integrated optical semiconductor (hereinafter referred to as optical semiconductor) technology is a next-generation technology for which many researches and investments are being made worldwide because it can make complex optical systems such as LiDAR and quantum sensors and computers into a single small chip.
In existing semiconductor technology, the goal was to achieve units of 5 nanometers or 2 nanometers, but increasing the degree of integration in optical semiconductor devices can be said to be a key technology that determines performance, price, and energy efficiency.
A research team led by Professor Sangsik Kim of the Department of Electrical and Electronic Engineering discovered a new optical coupling mechanism that can increase the degree of integration of optical semiconductor devices by more than 100 times.
University of Copenhagen researchers have invented a “quantum drum” that can measure pressure, a gas leak, heat, magnetism and a host of other things with extreme precision. It can even scan the shape of a single virus. The invention has now been adapted to work at room temperature and may be finding its way into our phones.
Humans have tried to measure the world around them since ancient times. Now, researchers are using the laws of quantum physics to develop one of the most sensitive measuring devices the world has ever seen. One day, it may even be yours. With two innovative solutions, researchers at the Niels Bohr Institute have found a way to get quantum technology into our pockets.
The heart of the apparatus could be called a “quantum drum”: It is a thin membrane that vibrates like a drum skin, but with so small an amplitude that the laws of quantum physics are needed to describe what’s happening. In other words, it’s vibrating really fast. This means the drum can be used as an ultra-precise measuring device—a quantum supersensor.
But in black holes, where a lot of mass is crammed into a very small region of space, these worlds collide and there is no theoretical framework that unifies the two.
“We have a great understanding of both individually, but it turns out extremely hard to combine these two theories,” says Weinfurtner. “The idea is that we want to understand how quantum physics behaves, on what we call a curved space time geometry.”
In the new setup, the black hole is represented by a tiny vortex inside a bell jar of superfluid helium, cooled to-271C. At this temperature, helium begins to demonstrate quantum effects. Unlike water, which can spin at a continuous range of speeds, the helium vortex can only swirl at certain fixed values. Ripples sent across the surface of the helium, tracked with nanometre precision by lasers and a high-resolution camera, represent radiation approaching a black hole.

Is there a multiverse, and if so, how should we think of ourselves within it? In many modern cosmological models, the universe includes more than one realm, with possibly different laws of physics, and these realms may or may not include intelligent observers. There is a longstanding puzzle about how, in such a scenario, we should calculate what we, as presumably intelligent observers ourselves, should expect to see. Today’s guest, Thomas Hertog, is a physicist and longstanding collaborator of Stephen Hawking. They worked together (often with James Hartle) to address these questions, and the work is still ongoing.
