Quantum Bit MRI Machine to See Shapes of Individual Biomolecules for Drug Research

Posted by in categories: biotech/medical, computing, particle physics, quantum physics

Drug discovery is a long and difficult process that requires a comprehensive understanding of the molecular structures of compounds under investigation. It’s difficult to have an idea of the precise shape of complex molecules such as proteins, but researchers at University of Melbourne in Australia have come up with a way of seeing the location of individual atoms within biomolecules.

Using quantum bits, most notably utilized in quantum computer research, the investigators offer a way of producing a magnetic resonance sensor and a magnetic field gradient that can work as a tiny MRI machine. The machine would have the resolution capable of seeing single atoms components of larger molecules. This MRI machine has yet to be actually built, but the steps have been laid out based on comprehensive theoretical work. If it proves successful in practice, the technology may overcome current imaging techniques that rely on statistical averages and don’t work well on molecules that don’t crystallize well.

“In a conventional MRI machine large magnets set up a field gradient in all three directions to create 3D images; in our system we use the natural magnetic properties of a single atomic qubit,” said lead author of the research Viktor Perunicic. “The system would be fabricated on-chip, and by carefully controlling the quantum state of the qubit probe as it interacts with the atoms in the target molecule, we can extract information about the positions of atoms by periodically measuring the qubit probe and thus create an image of the molecule’s structure.”

Precise quantum cloning: Possible pathway to secure communication

Posted by in categories: encryption, quantum physics

Physicists at The Australian National University (ANU) and University of Queensland (UQ) have produced near-perfect clones of quantum information using a new method to surpass previous cloning limits.

A global race is on to use quantum physics for ultra-secure encryption over long distances according to Prof Ping Koy Lam, node director of the ARC Centre of Excellence for Quantum Computation and Communication Technology (CQC2T) at ANU.

The exciting new age of quantum computing

Posted by in categories: biotech/medical, computing, encryption, military, quantum physics, security, space travel

What does the future hold for computing? Experts at the Networked Quantum Information Technologies Hub (NQIT), based at Oxford University, believe our next great technological leap lies in the development of quantum computing.

Quantum computers could solve problems it takes a conventional computer longer than the lifetime of the universe to solve. This could bring new possibilities, such as advanced drug development, superior military intelligence, greater opportunities for and enhanced encryption security.

QST And Osaka To Collaborate On Quantum And Radiological Research

Posted by in category: quantum physics

Based on the conclusion of this agreement, QST and Osaka University will greatly contribute to the promotion of science, technology and academia, and the creation of innovation in a variety of different fields. The institutes will create a new framework for collaboration and cooperation through the use of the research and development ability, state-of-the-art facilities, and human resources.

In addition, under this agreement, QST Kansai Photon Science Institute and the Osaka University Institute of Laser Engineering have simultaneously concluded a memorandum for cooperation in light and quantum beam science.

It is hoped that the development and utilization research of internationally-competitive power lasers will be greatly accelerated through systematic collaboration.

Scientists Generate the Fastest Electric Current Ever Measured Inside a Solid Material

Posted by in categories: computing, mobile phones, particle physics, quantum physics

Using ultrafast laser flashes, physicists from the Max Planck Institute have generated the fastest electric current that has ever been measured inside a solid material.

In the field of electronics, the principle ‘the smaller, the better’ applies. Some building blocks of computers or mobile phones, however, have become nearly as small today as only a few atoms. It is therefore hardly possible to reduce them any further.

Another factor for the performance of electronic devices is the speed at which electric currents oscillate. Scientists at the Max Planck Institute of Quantum Optics have now created electric currents inside solids which exceed the frequency of visible light by more than ten times They made electrons in silicon dioxide oscillate with ultrafast laser pulses. The conductivity of the material which is typically used as an insulator was increased by more than 19 orders of magnitude.

From the X-Files Dept: “Quantum Tunneling May Trigger Destruction of the Cosmos” (VIEW VIDEO)

Posted by in categories: existential risks, particle physics, quantum physics

Oh boy!


Space vacuum that appears to be stable due to the complete absence of substance in it, is likely to be fraught with great danger. The idea about the destruction of the universe is based on the hypothesis of vacuum instability. Any system in our world has a certain amount of potential energy. But, space vacuum is not as empty as it may seem to be. Vacuum in space is filled with quantum particles, which, in turn, may seek their own “stability” to annihilate the material world in its entirety during the process.

Scientists slam carbon out of diamonds to create the first quantum computing bridge

Posted by in categories: computing, quantum physics

What happens when you knock the carbon out of diamonds? You end up maintaining 100 percent quantum integrity; therefore, you can now transmit multitude of Qubits together over a long distance instead of 1 Qubit in one transmission and among multiple QC Devices.


New breakthrough paves the way for the first practical quantum computers

Quantum computers are a reality but unlike the first traditional computers, which were large enough to fill a room, most of today’s quantum computers are very small with one, five, or even 16 qubits at their core and getting to the point where we have a truly practical quantum computer is going to require component by component advances until, one day, we get to the point where all of the blocks “just work”.
