A molecular multi-qubit model system for quantum computing

Posted by in categories: computing, information science, quantum physics

Molecules could make useful systems for quantum computers, but they must contain individually addressable, interacting quantum bit centers. In the journal Angewandte Chemie, a team of researchers has now presented a molecular model with three different coupled qubit centers. As each center is spectroscopically addressable, quantum information processing (QIP) algorithms could be developed for this molecular multi-qubit system for the first time, the team says.

Computers compute using bits, while quantum computers use quantum bits (or qubits for short). While a conventional bit can only represent 0 or 1, a qubit can store two states at the same time. These superimposed states mean that a quantum computer can carry out parallel calculations, and if it uses a number of qubits, it has the potential to be much faster than a standard computer.

However, in order for the quantum computer to perform these calculations, it must be able to evaluate and manipulate the multi-qubit information. The research teams of Alice Bowen and Richard Winpenny, University of Manchester, UK, and their colleagues have now produced a molecular model system with several separate qubit units, which can be spectroscopically detected and the states of which can be switched by interacting with one another.

Webb Reveals Shells of Dust Surrounding Brilliant Binary Star System

Posted by in category: space

The latest image from NASA‘s James Webb Space Telescope is a new perspective on the binary star Wolf-Rayet 140, revealing details and structure in a new light. Astronomer Ryan Lau of NSF’s NOIRLab, principal investigator of the Webb Early Release Science program that observed the starhis thoughts on the observations.

On the night that my team’s Early Release Science observations of the dust-forming massive binary star Wolf-Rayet (WR) 140 were taken, I was puzzled by what I saw in the preview images from the Mid-Infrared Instrument (MIRI). There seemed to be a strange-looking diffraction pattern, and I worried that it was a visual effect created by the stars’ extreme brightness. However, as soon as I downloaded the final data I realized that I was not looking at a diffraction pattern, but instead rings of dust surrounding WR 140 – at least 17 of them.

I was amazed. Although they resemble rings in the image, the true 3D geometry of those semi-circular features is better described as a shell. The shells of dust are formed each time the stars reach a point in their orbit where they are closest to each other and their stellar winds interact. The even spacing between the shells indicates that dust formation events are occurring like clockwork, once in each eight-year orbit. In this case, the 17 shells can be counted like tree rings, showing more than 130 years of dust formation. Our confidence in this interpretation of the image was strengthened by comparing our findings to the geometric dust models by Yinuo Han, a doctoral student at the University of Cambridge, which showed a near-perfect match to our observations.

Caltech’s New Ultrafast Camera Captures Signals Traveling Through Nerve Cells

Posted by in categories: electronics, neuroscience

Reach out right now and touch anything around you. Whether it was the wood of your desk, a key on your keyboard, or the fur of your dog, you felt it the instant your finger contacted it.

Or did you?

In actuality, takes a bit of time for your brain to register the sensation from your fingertip. However, it does still happen extremely fast, with the touch signal traveling through your nerves at over 100 miles per hour. In fact, some nerve signals are even faster, approaching speeds of 300 miles per hour.

DeepMind breaks 50-year math record using AI; new record falls a week later

Posted by in categories: information science, mathematics, robotics/AI

Matrix multiplication is at the heart of many machine learning breakthroughs, and it just got faster—twice. Last week, DeepMind announced it discovered a more efficient way to perform matrix multiplication, conquering a 50-year-old record. This week, two Austrian researchers at Johannes Kepler University Linz claim they have bested that new record by one step.

In 1969, a German mathematician named Volker Strassen discovered the previous-best algorithm for multiplying 4×4 matrices, which reduces the number of steps necessary to perform a matrix calculation. For example, multiplying two 4×4 matrices together using a traditional schoolroom method would take 64 multiplications, while Strassen’s algorithm can perform the same feat in 49 multiplications.

Meta CEO Mark Zuckerberg said that his company is working with Ray-ban on creating new augmented reality glasses.

This product is coming sometime in the future, and it’s in addition to the existing partnership that Meta and Ray-ban have on Ray-ban Stories glasses. Zuckerberg said that AR glasses will get more sophisticated over time. Rocco Basilico of Luxotica showed off a demo of the new tech. And Ray-ban Stories will get a Spotify update.
