The World’s First MRI of a SINGLE Atom Is Here, and It Could Revolutionize Imaging

Magnetic resonance imaging is nothing new, but scientists were able to perform an MRI on a single atom. But how?

Scientists recently captured the smallest MRI ever while scanning an individual atom. The technique successfully reached a breakthrough level of resolution in the world of microscopy, the detailed MRI can reveal single atoms as well as different types of atoms based on their magnetic interactions.

This breakthrough has potential applications in all kinds of fields, like quantum computing where it could be used to design atomic-scale methods of storing info or when it comes to drug development, the ability to control individual atoms could potentially be used to study how proteins fold and then lead to the development of drugs for diseases like Alzheimers.

In a sense, the researchers combined a version of an MRI machine with a special instrument called a scanning tunneling microscope, which turned out to be a match made in microscopy heaven.

An MRI scanner creates an extremely strong magnetic field around whatever it’s trying to image, temporarily re-aligning the protons in your body with that magnetic field. Then the MRI machine pulses the sample (or patient) with a radiofrequency, which pulls the protons slightly out of alignment with the magnetic field. And after the brief radiofrequency pulse is over, the protons snap back into alignment with the field, and the energy that’s released as the protons move back into place with the magnetic field is what is detected and visualized by the machine.

And a scanning tunneling microscope is used for imaging really tiny surfaces, and it can pick up certain properties like size and molecular structure.

“Qutrit”: Complex quantum teleportation achieved for first time

Researchers from the Austrian Academy of Sciences and the University of Vienna have experimentally demonstrated what was previously only a theoretical possibility. Together with quantum physicists from the University of Science and Technology of China, they have succeeded in teleporting complex high-dimensional quantum states. The research teams report this international first in the journal “Physical Review Letters”.

In their study, the researchers teleported the quantum state of one photon (light particle) to another distant one. Previously, only two-level states (“qubits”) had been transmitted, i.e., information with values “0” or “1”. However, the scientists succeeded in teleporting a three-level state, a so-called “qutrit”. In quantum physics, unlike in classical computer science, “0” and “1” are not an ‘either/or’ – both simultaneously, or anything in between, is also possible. The Austrian-Chinese team has now demonstrated this in practice with a third possibility “2”.

Novel experimental method.

Newly Discovered State of Matter Could Vastly Enhance Computing

A team of physicists claims to have discovered a new state of matter — a breakthrough that could vastly improve traditional as well as quantum computing.

The new state, called “topological superconductivity,” could help to increase storage capabilities in electronic devices and enhance quantum computing.

A classic quantum theorem may prove there are many parallel universes

By Leah Crane

Some ideas about the quantum world appear to suggest there are many versions of you spread out across many parallel universes. Now, two scientists have formulated a proof that attempts to show this is really true.

The proof involves a fundamental construct in quantum mechanics called Bell’s theorem. This theorem deals with situations where particles interact with each other, become entangled, and then go their separate ways. It is what’s called a “no-go theorem”, one designed to show that some assumption about how the world works is not true.

Quantum teleportation shows up in 3D for the first time

For the first time, Chinese scientists have demonstrated the experiment of transferring quantum information in a 3D state.

Limited in a two-level state for a long time, the study paves the way to teleporting the complete quantum state of a particle, according to an article in American Physical Society a top peer-review journal.

According to Pan Jianwei, coauthor of the study known as the “father of quantum” in China, quantum teleportation is a new communication method to transfer quantum information – a particle’s quantum state in the micro-world.

What You Need To Know First About The Inexplicable World Of Quantum Computing

Down the road

The end game for quantum computing is a fully functional, universal fault-tolerant gate computer. To fulfill its promise, it needs thousands, maybe even millions, of qubits that can run arbitrary quantum algorithms and solve extremely complex problems and simulations.

Before we can build a quantum machine like that, we have a lot of development work to be done. In general terms, we need:
