Quantum computers are here, but aren’t yet particularly useful John D/Getty Images Quantum computers have long promised to solve certain problems faster than any ordinary, or classical, computer can. In fact, Google delivered on this promise in 2019, when it declared that its quantum computer had achieved quantum supremacy, performing a calculation …

One problem with quantum computers is that they have a high error rate Connie Zhou/IBM IBM has managed to dramatically reduce the number of quantum bits, or qubits, required to prevent errors in a quantum computer. Its latest approach to quantum error correction should bring down the number of qubits …

A US Air Force Reaper drone APFootage/Alamy Reports of AI drone “killing” its operator amounted to nothing This month we heard about a fascinating AI experiment from a US Air Force colonel. An AI-controlled drone trained to autonomously carry out bombing missions had turned on its human operator when told …

A strange quasiparticle could make error-proof quantum computers Yuichiro Chino/Getty Images Microsoft researchers have made a controversial claim that they have seen evidence of an elusive particle that could solve some of the biggest headaches in quantum computing, but some experts are questioning the discovery. Quantum computers process information using …

The Evobits “farm” in Romania mines the Ethereum and Zilliqa cryptocurrencies Akos Stiller/Bloomberg via Getty Images Quantum computers could be used to mine existing cryptocurrencies like bitcoin or future, more energy-efficient ones, slashing their electricity use, according to two new analyses. Cryptocurrencies that rely on a “proof of work” method …

It is thought that quantum computers will eventually be able to crack the encryption methods we use today, but exactly when this will happen is an open question. Now, one cryptographer has started a betting pool Source link

Sound vibrations can mimic properties of quantum computing Shutterstock/DmitrySteshenko Some properties of quantum computers can be imitated with sound trapped in a simple mechanical device. This has the advantage of being less fragile than quantum computers, while still replicating some of their properties. Quantum computers could eventually solve problems that …

Traditional computer chip designs are reaching their limit Yuichiro Chino/Moment RF/Getty Images The first practical example of a new kind of computer can complete calculations in minutes that would take a standard version longer than the age of the universe. This so-called digital memcomputer, which combines data storage and processing …

Quantum computers could be built that are based on sound CVI Textures / Alamy Stock Photo A crucial building block for quantum computers based on sound has been shown to work for the first time. One popular way of building quantum computers is to encode information into quantum states of …

WHAT’S the difference between a thimbleful of bacteria and a supercomputer? Believe it or not, the bacteria contain more circuits and more processing power. That is perhaps not so surprising when you consider that all life computes: from individual cells responding to chemical signals to complex organisms navigating their environment, …
