‘This is the first room-temperature quantum coherence of entangled quintets.’

A team of researchers from Kyushu University’s Faculty of Engineering, led by Associate Professor Nobuhiro Yanai, has shattered barriers by achieving quantum coherence at room temperature.

Researchers show room-temperature quantum coherence by observing the entangled quintet state with four electron spins in molecular systems.

The new method from ETH Zurich departs from traditional carbon capture, relying on temperature or pressure, minimizing energy consumption.

The details of the study, led by Maria Lukatskaya, Professor of Electrochemical Energy Systems at ETH Zurich, were published in the journal ACS.

AI can be easily used to spread misinformation during election campaigns. OpenAI wants to ensure that its tools do not do so.

Blogs, interviews, and speeches have been analyzed to find that Zuckerberg has transformed himself multiple times over the years.

Often criticized for his robotic expressions, Zuckerberg has undergone multiple transformations in his two decades of public life. Do we know the real Mark?

Betavolt wants to create batteries that will last a lifetime by 2025.

A Chinese startup called Betavolt has cooked up this itty-bitty nuclear battery — about the size of a little coin — which they claim can crank out electricity for 50 years straight, with no charging pit stops needed.

As the company leaps from development to the pilot stage, they’re gearing up for full-scale production and a grand entrance into the market pretty soon.

This article introduces new approaches to develop early fault-tolerant quantum computing (early-FTQC) such as improving efficiency of quantum computation on encoded data, new circuit efficiency techniques for quantum algorithms, and combining error-mitigation techniques with fault-tolerant quantum computation.

Noisy intermediate-scale quantum (NISQ) computers, which do not execute quantum error correction, do not require overhead for encoding. However, because errors inevitably accumulate, there is a limit to computation size. Fault-tolerant quantum computers (FTQCs) carry out computation on encoded qubits, so they have overhead for the encoding and require quantum computers of at least a certain size. The gap between NISQ computers and FTQCs due to the amount of overhead is shown in Fig. 1. Is this gap unavoidable? Decades ago, many researchers would consider the answer to be in the negative. However, our team has recently demonstrated a new, unprecedented method to overcome this gap. Motivation to overcome this gap has also led to a research trend that started at around the same time worldwide. These efforts, collectively called early fault-tolerant quantum computing “early-FTQC”, have become a worldwide research movement.

An organic artificial neuron that is based on a compact nonlinear electrochemical element can operate in a liquid and responds to the concentration of biological species in its surroundings, allowing its behaviour to be modulated, for example, by interfacing with the membranes of living cells.

Japanese chip maker Rohm is collaborating with venture company Quanmatic to improve electrical die sorting (EDS) in what appears to be the first use of quantum computing to optimize a commercial-scale manufacturing process on semiconductor production lines.

After a year of effort, the two companies have announced that full-scale implementation of the probe test technology can begin in April in Rohm’s factories in Japan and overseas. Testing and validation of the prototype indicate that EDS performance can be improved by several percentage points, improving significantly productivity and profitability.

Headquartered in Kyoto, Rohm produces integrated circuits (ICs), discrete semiconductors and other electronic components. It is one of the world’s leading suppliers of silicon carbide wafers and power management devices used in electric vehicles (EVs) and various industrial applications.
