Imagine for a second that the planet we live on, the solar system, our galaxy, and eventually the entire universe we see as infinite is no more than a simulation. What then?
According to a new theory by computer scientists, our universe may be simulated. So what we perceive as “ghosts” could be small pieces of evidence that suggest the universe we live in is simulated.
It’s called the simulation theory, and it proposes that we are no more than “avatars” in a universe that is entirely simulated.
We think of data storage as a modern problem, but even ancient civilizations kept records. While much of the world used stone tablets or other media that didn’t survive the centuries, the Incas used something called quipu which encoded numeric data in strings using knots. Now the ancient system of recording numbers has inspired a new way to encode qubits in a quantum computer.
With quipu, knots in a string represent a number. By analogy, a conventional qubit would be as if you used a string to form a 0 or 1 shape on a tabletop. A breeze or other “noise” would easily disturb your equation. But knots stay tied even if you pick the strings up and move them around. The new qubits are the same, encoding data in the topology of the material.
In practice, Quantinuum’s H1 processor uses 10 ytterbium ions trapped by lasers pulsing in a Fibonacci sequence. If you consider a conventional qubit to be a one-dimensional affair — the qubit’s state — this new system acts like a two-dimensional system, where the second dimension is time. This is easier to construct than conventional 2D quantum structures but offers at least some of the same inherent error resilience.
Self-organizing lasers could lead to new materials for sensing, computing, light sources, and displays by mimicking features of living systems.
Although many artificial materials have advanced properties, they have a long way to go to combine the versatility and functionality of living materials that can adapt to their situation. For example, in the human body bone and muscle continuously reorganize their structure and composition to better sustain changing weight and level of activity.
Now, scientists have demonstrated the first spontaneously self-organizing laser device, which can reconfigure when conditions change.
As the amount of data stored in devices and shared over the internet continuously increases, computer scientists worldwide are trying to devise new approaches to secure communications and protect sensitive information. Some of the most well-established and valuable approaches are cryptographic techniques, which essentially encrypt (i.e., transform) data and texts exchanged between two or more parties, so that only senders and receivers can view it in its original form.
Physical unclonable functions (PUFs), devices that exploit “random imperfections” unavoidably introduced during the manufacturing of devices to give physical entities unique “fingerprints” (i.e., trust anchors). In recent years, these devices have proved to be particularly valuable for creating cryptographic keys, which are instantly erased as soon as they are used.
Researchers at Peking University and Jihua Laboratory have recently introduced a new system to generate cryptographic primitives, consisting of two identical PUFs based on aligned carbon nanotube (CNT) arrays. This system, introduced in a paper published in Nature Electronics, could help to secure communications more reliably, overcoming some of the vulnerabilities of previously proposed PUF devices.
WASHINGTON — The Defense Innovation Unit is funding space projects that the agency hopes will spur commercial investments in satellite refueling technologies and support services for geostationary satellites.
“Imagine a world where every 18 to 24 months, you could simply upgrade the processor on a satellite in GEO the way that you upgrade your smartphone to take advantage of new processing power and new functionality,” said Steve “Bucky” Butow, director of the space portfolio at the Defense Innovation Unit.
DIU, based in Silicon Valley, is a Defense Department agency established in 2015 to help bring privately funded innovation into military programs.
The platform, still in the early development phase, is called Druglike, according to a press release that circulated on July 25. Its goals are ostensibly lofty, but the details are extremely sketchy, and Shkreli’s intentions have already drawn skepticism. It’s also unclear whether the enterprise will run Shkreli afoul of his lifetime ban from the pharmaceutical industry, which stemmed from the abrupt and callous 4,000 percent price hike of a life-saving drug that made him infamous.
Shkreli, who is named as a cofounder of Druglike, says the platform aims to make early-stage drug discovery more affordable and accessible. “Druglike will remove barriers to early-stage drug discovery, increase innovation and allow a broader group of contributors to share the rewards,” Shkreli said in the press release. “Underserved and underfunded communities, such as those focused on rare diseases or in developing markets, will also benefit from access to these tools.”
Generally, early-stage drug development can sometimes involve virtual screens to identify potential drug candidates. In these cases, pharmaceutical scientists first identify a “target”—a specific compound or protein that plays a critical role in developing a disease or condition. Then researchers look for compounds or small molecules that could interfere with that target, sometimes binding or “docking” directly to the target in a way that keeps it from functioning. This can be done in physical labs using massive libraries of compounds in high-throughput chemical screens. But it can also be done virtually, using specialized software and a lot of computing power, which can be resource-intensive.
As part of a $1 billion initiative, Google has hired researchers at Sydney’s biggest unis to find applications for the quantum computer it’s building in the US.

Quantum mechanic discoveries are some of the most groundbreaking discoveries that scientists can make as they allow us to get a better understand of the space and matter around us. From multiple dimensions to quantum superposition, there are many things that are difficult for scientists and physicists to explain. Hopefully we can clear up some of the confusion!

Quantum computers, devices that exploit quantum phenomena to perform computations, could eventually help tackle complex computational problems faster and more efficiently than classical computers. These devices are commonly based on basic units of information known as quantum bits, or qubits.
