China is getting their new Quantum communications infrastructure being prepped for deployment and adoption. Next month, the Quantum Satellite is launched to enable wireless communication that is secured and can block hacking; and we know what the reverse means for everyone else.

Now, China has unveiled that they have been planning and getting their cities ready for Quantum communications/ network adoption.

China leads the world in quantum communications.

China has already begun to establish quant.

Change is coming; will you be ready?
I remember many decades ago when folks were trying to learn a new OS that changed businesses, governments/ educational institutions, and households around the world. That OS was called Windows; and hearing the stories as well as watching people try to use a PC and a mouse was interesting then.

Now, the world will again go through a large scale metamorphosis again when more and more QC is evolved and made available over the next 5 to 7 years in the technology mainstream. Change is often necessary and often can be good as well.

You might ask yourself, “What is quantum computing, and how do I get involved?”

Before we begin to explain quantum computing, a brief glimpse of the past is essential to understand how quantum computing came to be.

From our very first laptop to the laptops we have today, it is clear that technology is exponentially advancing faster than our expectations. Phones and computers get thinner and faster, but why? Thanks to the effects of Moore’s Law, which states that the number of transistors in a dense circuit will double approximately every two years, the amount of “stuff” needed to be put on a board is more densely packed.

Change is coming; and Microsoft will be there.

With funding from Microsoft, a Purdue research team known as ‘Station Q Purdue’ will research potential methods of quantum computing.

“In order to see if these ideas that (Microsoft) has are realistic, whether they can be experimentally verified and then put to use, (Microsoft) has teamed up with certain experimentalists around the world,” said professor Michael Manfra, the director of Station Q Purdue.

Microsoft’s quantum computing research is done under their own Microsoft Station Q. Station Q Purdue is part of the network of other Station Q research teams that Microsoft has established internationally to study potential methods of quantum computing.

The opportunity for intellectual freedom is what drew Anna Ijjas to the Princeton Center for Theoretical Science. As an associate research scholar, Ijjas studies basic questions about the universe’s origin and future. “PCTS provided an environment that encouraged me to question established paradigms and pursue unexplored possibilities,” said Ijjas, who is Princeton’s John A. Wheeler Postdoctoral Fellow in cosmology and astroparticle physics. “Independence and creativity are real values at the center.”

Those values were on display at a conference in May to celebrate the 10th anniversary of the center, which trains early-career researchers and provides a place where theoretical scientists — defined as those who use mathematics to study the natural world — can tackle the biggest questions in science, from the search for dark matter to global climate simulations to theories of quantum gravity.

“The range of topics presented at the PCTS@ten conference demonstrates that we’ve reached the goal we set 10 years ago, which is to develop a new breed of theorists with a much broader view of science than they would normally get from typical postdoctoral training,” said Paul Steinhardt, Princeton’s Albert Einstein Professor in Science and the center’s director since 2007.

Technology, meet your future beyond AI & Quantum.

While scientists study the possibilities of storing data in DNA, the web magazine Engadget reports that another group of researchers are looking into the possibility of utilizing living cells for next-generation computing.

The latest studies have developed a method of integrating both analog and digital computing into gene-based circuits. This allowed researchers to convert analog chemical reactions into binary output, or the ones and zeros that regular computers understand.

Apart from the obvious applications on general computing, gene-based circuitry can also be helpful to the medical field where it can be programmed to treat various diseases. In fact, clinical trials have been scheduled to use gene circuitry to treat gut diseases within the year. Alfred Bayle.

A black hole may carry “soft hair,” low-energy quantum excitations that release information when the black hole evaporates.

Four decades ago, Stephen Hawking proposed that black holes could destroy information—a conclusion that is incompatible with standard laws of quantum physics. This idea started a controversy known as the “black hole information problem” that even now has not been resolved. A new study by Hawking himself and Malcom Perry, both at the University of Cambridge, and by Andrew Strominger at Harvard University shows that some of the assumptions that led to the information problem might be wrong [1]. Their results do not completely solve the problem, but point to a promising research direction that might lead to its long-awaited solution.

According to Einstein’s general theory of relativity, stationary black holes are completely determined by just three observable parameters: their mass, charge, and angular momentum. Almost none of the information about what fell into the black hole is visible from the outside. Physicist John Wheeler described this idea by saying that “black holes have no hair.”

Since 2001, I have worked, experimented, and researched in parallel tech and bio/medical technology space. I did this because I could see that at some point that these two fields would eventually overlap and eventually merge in many areas. Today, we’re already see the duplicated use of technology in both the medical/ life sciences and the same technology used to advance the technology in general such as Quantum tech, nanotech, etc. Here is another example of this trend.

Silicon forms the basis of everything from solar cells to the integrated circuits at the heart of our modern electronic gadgets. However the laser, one of the most ubiquitous of all electronic devices today, has long been one component unable to be successfully replicated in this material. Now researchers have found a way to create microscopically-small lasers directly from silicon, unlocking the possibilities of direct integration of photonics on silicon and taking a significant step towards light-based computers.

Whilst there has been a range of microminiature lasers incorporated directly into silicon over the years, including melding germanium-tin lasers with a silicon substrate and using gallium-arsenide (GaAs) to grow laser nanowires, these methods have involved compromise. With the new method, though, an international team of researchers has integrated sub-wavelength cavities, the basic components of their minuscule lasers, directly onto the silicon itself.

To help achieve this, a team of collaborating scientists from Hong Kong University of Science and Technology, the University of California, Santa Barbara, Sandia National Laboratories and Harvard University, first had to find a way to refine silicon crystal lattices so that their inherent defects were reduced significantly enough to match the smooth properties found in GaAs substrate lasers. They did this by etching nano-patterns directly onto the silicon to confine the defects and ensure the necessary quantum confinement of electrons within quantum dots grown on this template.

In a feat that demonstrates the feasibility of using satellites to transmit uncrackable quantum messages, scientists have measured the quantum properties of photons sent to space and back again.

Physicists beamed the blips of light up to a satellite that reflected them back to Earth. Upon the photons’ return, the team, led by Paolo Villoresi of the University of Padua in Italy, observed a property known as quantum interference. That confirmed that the particles’ quantum traits remained intact over the 5,000-kilometer space voyage. The team reports the advance in a paper to be published in Physical Review Letters.

The technique could one day lead to quantum cryptography by satellite, allowing users to send snoop-proof encryption keys for encoding secret information. “It’s important for the sake of secure communication and advancement of physics,” says Villoresi. But that’s not the only reason he took on the challenge. “I can more honestly say that it’s cool.”
