In the quantum world, dynamic localization is when a system stays the same temperature even when it has an energy input that should be making it hotter, and physicists have now pushed this phenomenon further than ever before. A team of researchers investigated mathematical models to see if dynamical localization can still arise when many quantum particles interact.

This Computer Is About to Change The World
What They Won’t Tell You About The Mind… | The Quantum Computer
YouAreCreators was created to share one of the greatest secrets of the Universe, and the secret is, we literally create our reality! No…really (Quantum Physics now proves this) We are all governed by a set of Universal Laws, and these laws were created by GOD, to aid us in creating the life we desire. One of these laws is known as the “Law Of Attraction”, or the law of “Reaping and Sowing”. This law simply states, whatever you give out in Thought, Word, Feeling, and Action is returned to us. Whether the return is negative, or positive, failure or success, is all up to what you give out.
How Do Quantum Computers Work?
All the computing devices rely on a very basic ability to store and manipulate information. The classical computers manipulate individual bits and store information as binary 0 and 1 states. But in quantum computers, that’s not the case. Information is stored in something called qubits. Now, what are these?

Researchers might have broken one of the biggest obstacles to practical quantum computers with something called ‘hot’ qubits.
As many of you already know, the quantum computer is built around the quantum bit, or qubit. The colder and more isolated the qubit is, the less likely it is to flip to another quantum state when it’s not supposed to. But well-isolated qubits are also difficult to keep cold, and the more qubits a computer has, the more heat the system generates, and so we have to figure out how to keep these large quantum computers operating at an optimal temperature either by improving the cooling systems or by creating qubits that can operate at warmer temperatures. This is where researchers believe they have made a major breakthrough by using quantum dots embedded in silicon rather than basing their qubits off superconductors. This approach allows the qubits to operate at hotter temperatures…like 1.5 kelvin hot. That’s 15 times hotter than the main competing chip-based technology being developed by Google, IBM, and others.
How an Accident Sparked a Quantum Computing Breakthrough
An accident in a lab in Australia has led to a breakthrough discovery—one that might even change how we approach building quantum computers. As we know, quantum computers are much more difficult to make quite as small as their classical counterparts, and one dream for future quantum computers is a best-of-both-worlds scenario, where single atoms embedded in silicon can be manipulated with magnetic fields, producing more compact chips with millions of qubits on them. And now, it seems, these researchers in Australia have stumbled across a way to control nuclear qubits with more-manageable electric fields.
The Future of Quantum Computing Could Live on a Cryogenic Chip
It seems like quantum computers will likely be a big part of our computing future—but getting them to do anything super useful has been famously difficult. Lots of new technologies are aiming to get commercially viable quantum computing here just a little bit faster, including one innovation that shrinks quantum technology down onto a chip. Enter: the cryogenic chip. But first, a quick refresher on how quantum computing works. Unlike a classical bit, a quantum computer uses quantum bits, or qubits, to make calculations. These qubits have the potential to be super powerful, providing quantum computers with the potential to run really complex calculations exponentially faster than classical computers. But qubits are also really, really hard to both make and control. Today, quantum computers have less than 100 qubits, but in order to tackle problems we want answers to, we will need to scale up to million-qubit systems. That means that we will need a more sustainable way to control the behavior of qubits. One solution? A cryogenic computer chip. Intel just debuted a chip its calling Horse Ridge, a technology that takes the electronics needed to control the qubits, and puts them on a chip that’s capable of functioning at about 4 Kelvin, so they can live inside the cryogenic chamber with the qubits. But how does this cryogenic chip work, how realistic of a solution is it really, and what could it mean for the future of quantum computing?
How Quantum is re-imaging the electric car battery
Dr. Jeff Welser, vice president of IBM Research Almaden, pacific rim labs, and global exploratory science, tells Tonya Hall about how quantum computing is necessary to accurately model large molecule interactions and how IBM Research Almaden is putting that theory to use when re-imaging eclectic car batteries.
Quantum computing and quantum supremacy, explained
Quantum computing could change the world. It could transform medicine, break encryption and revolutionize communications and artificial intelligence. Companies like IBM, Microsoft and Google are racing to build reliable quantum computers. China has invested billions. Recently, Google claimed that it had achieved quantum supremacy – the first time a quantum computer has outperformed a traditional one. But what is quantum computing and how do quantum computers work?
