AMD files teleportation patent to supercharge quantum computing

Posted by in categories: computing, quantum physics, time travel

That’s teleportation for Qubits, not for humans, sadly.


AMD has proposed a patent for ‘teleportation,’ meaning things could be about to get much more efficient around here. With the incredible technological feats humanity achieves on a daily basis, and Nvidia’s Jensen going off on one last year about GeForce holodecks and time machines, it’s easy for us to slip into a headspace that lets us believe genuine human teleportation is just around the corner.

“Finally,” you sigh, mouthing the headline to yourself. “Goodbye work commute, hello popping to Japan for an authentic Ramen on my lunch break.”

The first experimental realization of a dissipative time crystal

Posted by in categories: quantum physics, space

A time crystal is a unique and exotic phase of matter first predicted by the American physicist Frank Wilczek in 2012. Time crystals are temporal analogs of more conventional space crystals, as both are based on structures characterized by repeating patterns.

Instead of forming repetitive patterns across three-dimensional (3D) space, as space crystals do, time crystals are characterized by changes over time that occur in a set pattern. While some research teams have been able to realize these exotic phases of matter, so far, these realizations have only been achieved using closed systems. This raised the question of whether time crystals could also be realized in open systems, in the presence of dissipation and decoherence.

Researchers at the Institute of Laser Physics at the University of Hamburg have recently realized a time crystal in an open quantum system for the first time. Their paper, published in Physical Review Letters, could have important implications for the study of exotic phases of matter in quantum systems.

Researchers use gold film to enhance quantum sensing with qubits in a 2D material

Posted by in categories: biological, engineering, quantum physics

Quantum sensing is being used to outpace modern sensing processes by applying quantum mechanics to design and engineering. These optimized processes will help beat the current limits in processes like studying magnetic materials or studying biological samples. In short, quantum is the next frontier in sensing technology.

As recently as 2,019 spin defects known as qubits were discovered in 2D materials (hexagonal boron nitride) which could amplify the field of ultrathin . These scientists hit a snag in their discovery which has unleashed a scientific race to resolve the issues. Their sensitivity was limited by their low brightness and the low contrast of their magnetic resonance signal. As recently as two weeks ago on August 9 2021, Nature Physics published an article titled “quantum sensors go flat,” where they highlighted the benefits and also outlined current shortfalls of this new and exciting means of sensing via qubits in 2D materials.

A team of researchers at Purdue took on this challenge of overcoming qubit signal shortcomings in their work to develop ultrathin quantum sensors with 2D materials. Their publication in Nano Letters was published today, September 2 2021, and they have solved some of the critical issues and yielded much better results through experimentation.

Unraveling quantum interactions of 100,000 atoms in gases

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

Silvia Musolino defended her Ph.D. on new theoretical insights in quantum physics by studying gases at the lowest temperatures consisting of many atoms.

A practical way to study is provided by gases that have extremely low density and consist of many , often more than one hundred thousand, cooled down to temperatures close to the absolute zero. Silvia Musolino studied different types of interactions between these atoms, providing new pathways for future research on new technologies such as quantum computers.

Quantum mechanical laws govern the physics at the atomic scale and is distinguished by , which deals mainly with we can see, hear, or touch. However, even quantum mechanics influences our daily life. Transistors, which are crucial components of electronic devices, are based on quantum mechanical effects. Moreover, quantum mechanics paves the way for new technologies that may strongly impact our lives, such as quantum computers.

Nano ‘camera’ made using molecular glue allows real-time monitoring of chemical reactions

Posted by in categories: chemistry, nanotechnology, quantum physics

Researchers have made a tiny camera, held together with ‘molecular glue’ that allows them to observe chemical reactions in real time.

The device, made by a team from the University of Cambridge, combines tiny semiconductor nanocrystals called and gold nanoparticles using molecular glue called cucurbituril (CB). When added to water with the molecule to be studied, the components self-assemble in seconds into a stable, powerful tool that allows the real-time monitoring of chemical reactions.

The camera harvests light within the semiconductors, inducing electron transfer processes like those that occur in photosynthesis, which can be monitored using incorporated gold nanoparticle sensors and spectroscopic techniques. They were able to use the camera to observe which had been previously theorized but not directly observed.

Paving the path to electrically-pumped lasers from colloidal-quantum-dot solutions

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

In a new review article in Nature Photonics, scientists from Los Alamos National Laboratory assess the status of research into colloidal quantum dot lasers with a focus on prospective electrically pumped devices, or laser diodes. The review analyzes the challenges for realizing lasing with electrical excitation, discusses approaches to overcome them, and surveys recent advances toward this objective.

“Colloidal quantum dot lasers have tremendous potential in a range of applications, including integrated optical circuits, wearable technologies, lab-on-a-chip devices, and advanced medical imaging and diagnostics,” said Victor Klimov, a senior researcher in the Chemistry division at Los Alamos and lead author of the cover article in Nature Photonics. “These solution-processed quantum dot present unique challenges, which we’re making good progress in overcoming.”

Heeyoung Jung and Namyoung Ahn, also of Los Alamos’ Chemistry division, are coauthors.

The Smallest Engine in the World Is Literally an Ion

Posted by in categories: particle physics, quantum physics

Circa 2019


An international team of physicists have created what they’re calling the world’s smallest engine. How small is it? The entire engine is a single calcium ion, making it around 10 billion times smaller than a car engine.

The experimental engine was conceived by an international team led by Professor Ferdinand Schmidt-Kaler and Ulrich Poschinger of Johannes Gutenberg University in Mainz, Germany. The engine is electrically charged, which makes it easy to trap using electric fields. The moving parts of the engine are the ion’s “intrinsic spin.” On an atomic level, spin is a measurement of an atom’s angular momentum.

Quantum Computing Platform Accelerates Transition from Bulk Optics to Integrated Photonics on a Silicon Chip Smaller Than a Penny

The quantum computing market is projected to reach $65 billion by 2,030 a hot topic for investors and scientists alike because of its potential to solve incomprehensibly complex problems.

Drug discovery is one example. To understand drug interactions, a pharmaceutical company might want to simulate the interaction of two molecules. The challenge is that each molecule is composed of a few hundred atoms, and scientists must model all the ways in which these atoms might array themselves when their respective molecules are introduced. The number of possible configurations is infinite—more than the number of atoms in the entire universe. Only a quantum computer can represent, much less solve, such an expansive, dynamic data problem.
