Why Quantum Mechanics Defies Physics

Posted by in categories: business, mathematics, quantum physics

The full, weird story of the quantum world is much too large for a single article, but the period from 1905, when Einstein first published his solution to the photoelectric puzzle, to the 1960’s, when a complete, well-tested, rigorous, and insanely complicated quantum theory of the subatomic world finally emerged, is quite the story.

This quantum theory would come to provide, in its own way, its own complete and total revision of our understanding of light. In the quantum picture of the subatomic world, what we call the electromagnetic force is really the product of countless microscopic interactions, the work of indivisible photons, who interact in mysterious ways. As in, literally mysterious. The quantum framework provides no picture as to how subatomic interactions actually proceed. Rather, it merely gives us a mathematical toolset for calculating predictions. And so while we can only answer the question of how photons actually work with a beleaguered shrug, we are at least equipped with some predictive power, which helps assuage the pain of quantum incomprehensibility.

A logical magic state with fidelity beyond distillation threshold realized on superconducting quantum processor

Posted by in categories: computing, encryption, quantum physics

Quantum computers have the potential to outperform conventional computers on some tasks, including complex optimization problems. However, quantum computers are also vulnerable to noise, which can lead to computational errors.

Engineers have been trying to devise fault-tolerant approaches that could be more resistant to noise and could thus be scaled up more robustly. One common approach to attain fault-tolerance is the preparation of magic states, which introduce so-called non-Clifford gates.

Researchers at University of Science and Technology of China, the Henan Key Laboratory of Quantum Information and Cryptography and the Hefei National Laboratory recently demonstrated the preparation of a logical magic state with fidelity beyond the distillation threshold on a superconducting quantum processor. Their paper, published in Physical Review Letters, outlines a viable and effective strategy to generate high-fidelity logical magic states, an approach to realize fault-tolerant quantum computing.

We Just Got a Major Step Closer to Teleporting Images Using Only Light

Posted by in categories: innovation, quantum physics

Teleportation of quantum states promises to play a central role in securing the information superhighway of tomorrow.

In spite of the headway that’s been made, the process remains slow and kind of clunky. That could change, with scientists using a new process that could efficiently teleport states of light to form an image using a single pair of entangled photons.

The team, from South Africa, Germany, and Spain, is hopeful that the innovation may help build the secure networks of the future: if the key data isn’t transmitted, then it can’t be stolen.

Applying MXene to quantum dot photovoltaic cells simultaneously increases efficiency and stability

Posted by in categories: engineering, quantum physics, solar power, sustainability

A research team led by Professor Jong-min Choi of the Department of Energy Engineering has developed a technology that can significantly improve the efficiency of quantum dot photovoltaic cells by introducing organic solvent dispersible MXene.

The findings were published in Advanced Energy Materials (“Organic solvent dispersible MXene integrated colloidal quantum dot photovoltaics”).

How A Laser-Plasma Collider Can Turn Light Into Matter In A Matter Of Seconds

Posted by in categories: particle physics, quantum physics

A team led by researchers at Osaka University and University of California, San Diego has conducted simulations of creating matter solely from collisions of light particles. Their method circumvents what would otherwise be the intensity limitations of modern lasers and can be readily implemented by using presently available technology. This work might help experimentally test long-standing theories such as the Standard Model of particle physics, and possibly the need to revise them.

One of the most striking predictions of quantum physics is that matter can be generated solely from light (i.e., photons), and in fact, the astronomical bodies known as pulsars achieve this feat. Directly generating matter in this manner has not been achieved in a laboratory, but it would enable further testing of the theories of basic quantum physics and the fundamental composition of the universe.

In a study published in Physical Review Letters, a team led by researchers at Osaka University has simulated conditions that enable photon–photon collisions, solely by using lasers. The simplicity of the setup and ease of implementation at presently available laser intensities make it a promising candidate for near-future experimental implementation.
