Quantum computing
🖥️ Quantum computer demonstrates controlled advantage over supercomputer for the first time
The Willow chip calculates molecular structures 13,000 times faster than one of the world's fastest supercomputers. The technique can be used to measure distances in molecules and provide more information about chemical structure than today's methods.
📡 Longest ultra-secure quantum communication link between continents
Researchers established a 12,900-kilometer quantum communication link between Beijing and Stellenbosch University via satellite, which uses the laws of physics to make eavesdropping impossible.
🧮 Google's quantum computer performs calculation in 5 minutes that would take longer than the universe's existence for a supercomputer
Google's new quantum computer solved a calculation in five minutes that would take longer than the universe's existence to solve with a regular supercomputer. The time it would take the supercomputer to do the calculation is nearly a million billion times longer than the age of the universe.
🏆 Competition to accelerate quantum computers' societal benefits
XPRIZE has launched a global competition worth $5 million to develop practical quantum algorithms. The competition aims to accelerate the development of quantum computer applications that can solve important societal problems.
👩💻 Google paves the way for practically usable quantum computers
Google has built a quantum computer that makes fewer errors as it scales up. The company has passed an important threshold for error correction in quantum units. This paves the way for practically usable quantum computers in the future.
👩💻 IBM's quantum breakthrough - real-world applications within two years
IBM's quantum computer successfully completes a 'benchmark' experiment. Researchers work around quantum noise to get reliable results. The achievement suggests quantum computers could have practical applications within two years.
