The physicists, constructing “time crystals”, happened on an error correction technique for quantum computers. The rest is the story we all wish we were in.
I disagree with this because consciousness ends after death.
Since the beginning of time, man has questioned what happens after death. Of course, there are a variety of typical answers to this question, but scientists may have just added an infinite number of other possibilities, just to shake things up.
According to Robert Lanza, M.D, death is actually a door to an endless number of universes. Furthermore, during our life, Lanza asserts that anything that possibly can happen is happening in some universe. He continues to explain that death does not exist in these scenarios since all of these possibilities are taking place at the same time. The only reason we associate our consciousness with our physical body is due to energy operating around in our brains.

Time is the most valuable thing that we have in our lives, and we never seem to have enough of it. Whether you’re trying to scratch out more time, or just making the most of what you have, there’s no denying that being able to reverse time would be handy.
“We also demonstrated that even very low-power microwave pulses can be detected efficiently using our protocol.”
A team of scientists has devised a means of using quantum mechanics to “view” objects indirectly. The new method could improve measurements for quantum computers and other systems. It brings together the quantum and classical worlds.
They have found no signs of the event yet.
Deep in Italy’s Gran Sasso mountains, in the National Institute for Nuclear Physics’ (INFN) underground laboratories, researchers have been searching for proof of a very small violation of a fundamental quantum tenet called the Pauli exclusion principle, according to an article by Phys.org published on Monday.
The principle, that is applied to everything, dictates that electrons can only arrange themselves in certain specific ways in atoms. These arrangements make it so we are made of solid matter.

A research group led by Prof. Wu Kaifeng from the Dalian Institute of Chemical Physics (DICP), Chinese Academy of Sciences recently reported the successful initialization, coherent quantum-state control, and readout of spins at room temperature using solution-grown quantum dots, which represents an important advance in quantum information science.
The study was published in Nature Nanotechnology on Dec 19th.

We see the world around us because light is being absorbed by specialized cells in our retina. But can vision happen without any absorption at all—without even a single particle of light? Surprisingly, the answer is yes.
Imagine that you have a camera cartridge that might contain a roll of photographic film. The roll is so sensitive that coming into contact with even a single photon would destroy it. With our everyday classical means there is no way there’s no way to know whether there’s film in the cartridge, but in the quantum world it can be done. Anton Zeilinger, one of the winners of the 2022 Nobel Prize in Physics, was the first to experimentally implement the idea of an interaction-free experiment using optics.
Now, in a study exploring the connection between the quantum and classical worlds, Shruti Dogra, John J. McCord, and Gheorghe Sorin Paraoanu of Aalto University have discovered a new and much more effective way to carry out interaction-free experiments. The team used transmon devices—superconducting circuits that are relatively large but still show quantum behavior—to detect the presence of microwave pulses generated by classical instruments. Their research was recently published in Nature Communications.
For a long time, researchers assumed that phonons could not contribute to the thermal Hall effect because of their lack of charge and spin. New work challenges this assumption.
How heat flows in interacting quantum many-body systems is one of the most interesting open problems in condensed-matter physics. Understanding thermal transport is particularly challenging in systems where charge-carrier contributions to energy transport are strongly suppressed, such as in insulators and superconductors. In such systems, heat transport cannot therefore be understood in terms of electronic carriers alone. In insulators, acoustic phonons are among the main energy carriers in an insulator. However, determining how and to what extent phonons contribute to heat transport in a material is the Achilles’ heel of interpreting thermal conductivity measurements. In particular, whether or not phonons can contribute to the thermal Hall effect—in which a temperature gradient in one direction produces heat flow in a perpendicular direction—remains an open question.
A pressing quest in the field of nanoelectronics is the search for a material that could replace silicon. Graphene has seemed promising for decades. But its potential has faltered along the way, due to damaging processing methods and the lack of a new electronics paradigm to embrace it. With silicon nearly maxed out in its ability to accommodate faster computing, the next big nanoelectronics platform is needed now more than ever.
Walter de Heer, Regents’ Professor in the School of Physics at the Georgia Institute of Technology, has taken a critical step forward in making the case for a successor to silicon. De Heer and his collaborators have developed a new nanoelectronics platform based on graphene —a single sheet of carbon atoms. The technology is compatible with conventional microelectronics manufacturing, a necessity for any viable alternative to silicon.
In the course of their research, published in Nature Communications, the team may have also discovered a new quasiparticle. Their discovery could lead to manufacturing smaller, faster, more efficient and more sustainable computer chips, and has potential implications for quantum and high-performance computing.
In physics, weak microwave signals can be amplified with minimal added noise. For instance, artificial quantum systems based on superconducting circuits can amplify and detect single microwave patterns, although at millikelvin temperatures. Researchers can use natural quantum systems for low-noise microwave amplification via stimulated emission effects; however, they generate a higher noise at functionalities greater than 1 Kelvin.
In this new work, published in the journal Science Advances, Alexander Sherman and a team of scientists in chemistry at the Technical-Israel Institute of Technology, Haifa, used electron spins in diamond as a quantum microwave amplifier to function with quantum-limited internal noise above liquid nitrogen temperatures. The team reported details of the amplifier’s design, gain, bandwidth, saturation power and noise to facilitate hitherto unavailable applications in quantum science, engineering and physics.
