Superconducting metamaterial traps quantum light

Conventional computers store information in a bit, a fundamental unit of logic that can take a value of 0 or 1. Quantum computers rely on quantum bits, also known as a “qubits,” as their fundamental building blocks. Bits in traditional computers encode a single value, either a 0 or a 1. The state of a qubit, by contrast, can simultaneously have a value of both 0 and 1. This peculiar property, a consequence of the fundamental laws of quantum physics, results in the dramatic complexity in quantum systems.

Quantum computing is a nascent and rapidly developing field that promises to use this complexity to solve problems that are difficult to tackle with conventional computers. A key challenge for computing, however, is that it requires making large numbers of qubits work together—which is difficult to accomplish while avoiding interactions with the outside environment that would rob the qubits of their quantum properties.

New research from the lab of Oskar Painter, John G Braun Professor of Applied Physics and Physics in the Division of Engineering and Applied Science, explores the use of superconducting metamaterials to overcome this challenge.

The Physics of Information: Quantum Potentiality to Classical Actuality of Your Experiential Reality

Physicists face the same hard problem as neuroscientists do: the problem of bridging objective description and subjective experience. Physics has encountered consciousness. Quantum theory says an object remains in a superposition of possibilities until observed. We can consider a quantum state as being about our knowledge rather than a direct description of physical reality. The physics of information just may be that bridging of quantum-to-digital reality of subjective experience. We are now at the historic juncture when quantum computing could reveal quantum information processing underpinnings of subjectivity. Quantum mechanics is a spectacularly successful theory of fundamental physics that allows us to make probabilistic predictions derived from its mathematical formalism, but the theory doesn’t tell us precisely how these probabilities should be interpreted in regards to phenomenology, i.e. our experiential reality. There are basically three main interpretive camps within quantum mechanics from which stem at least a dozen further interpretations.

A new way to count qubits

Researchers at Syracuse University, working with collaborators at the University of Wisconsin (UW)-Madison, have developed a new technique for measuring the state of quantum bits, or qubits, in a quantum computer.

Their findings are the subject of an article in Science magazine, which elaborates on the experimental efforts involved with creating such a technique.

The Plourde Group—led by Britton Plourde, professor of physics in Syracuse’s College of Arts and Sciences (A&S)—specializes in the fabrication of superconducting devices and their measurement at low temperatures.

Errors: I made an off hand comment about adding efficiencies in the video without thinking. This is obviously incorrect, but the final calculation does in fact multiply the efficiencies.

“Conquering the negative effects of aging is one of the oldest dreams of humanity, and now through the steady progress of science, we are poised to fulfill that dream.

Whether this occurs in 20 years or 200 is largely a question of funding. The best way to accelerate this process is by mobilizing those who desire the option of a longer and healthier life into a cohesive social force — crowdfunding relevant research and advocating for its benefits to society.

On lifespan.io researchers post projects related to longevity or age related disease, and receive funds from contributors to fulfill their goals. Contributors, in turn, are able to exercise agency in the development of potentially life changing research, as well as receiving rewards specified by the project creators.” “Keith Comito is a computer programmer and mathematician whose work brings together a variety of disciplines to provoke thought and promote social change. He has created video games, bioinformatics programs, musical applications, and biotechnology projects featured in Forbes and NPR. In addition to developing high-profile mobile applications, he explores the intersection of technology and biology at the Brooklyn community lab Genspace, where he helped to create games which allow players to direct the motion of microscopic organisms. He earned a B.S. in Mathematics, B.S. in Computer science, and M.S. in Applied Mathematics at Hofstra University, where his work included analysis of the LMNA protein.”
