NASA has temporarily halted operations of its quantum computer after it produced unexpected results. The computer, which is still under development, is designed to simulate complex systems such as those found in space. However, during a recent test, the computer-generated results that were inconsistent with known physical laws.

NASA scientists are currently investigating the cause of the anomaly. They are also working to develop safeguards to prevent similar incidents from happening in the future.

The shutdown of the quantum computer is a setback for NASA’s efforts to develop new technologies for space exploration. However, it is also an opportunity to learn more about the potential of quantum computing.

Residents on Chicago’s Southeast Side are urging city and state officials to slow down the development of a quantum computing campus.

What is consciousness, and is it really inherent only to humans? In this video, we explore whether consciousness is not only inherent in humans, but also in animals, artificial intelligence, and even the universe itself. We dive into the complex concepts of panpsychism and quantum consciousness, looking at Roger Penrose and Stuart Hameroff’s Orch-OR project, which claims that quantum processes in microtubules may underlie consciousness. We will analyze Giulio Tononi’s Integral Information Theory, which proposes to quantify the level of consciousness in any system.

A team of Chinese researchers, led by Wang Chao from Shanghai University, has demonstrated that D-Wave’s quantum annealing computers can crack encryption methods that safeguard sensitive global data.

This breakthrough, published in the Chinese Journal of Computers, emphasizes that quantum machines are closer than expected to threatening widely used cryptographic systems, including RSA and Advanced Encryption Standard (AES).

The research team’s experiments focused on leveraging D-Wave’s quantum technology to solve cryptographic problems. In their paper, titled “Quantum Annealing Public Key Cryptographic Attack Algorithm Based on D-Wave Advantage,” the researchers explained how quantum annealing could transform cryptographic attacks into combinatorial optimization problems, making them more manageable for quantum systems.

How do we assess quantum advantage when exact classical solutions are not available?

A quantum advantage is a demonstration of a solution for a problem for which a quantum computer can provide a demonstrable improvement over any classical method and classical resources in terms of accuracy, runtime…

Today, algorithms designed to solve this problem mostly rely on what we call variational methods, which are algorithms guaranteed to output an energy for a target system which cannot be lower than the exact solution — or the deepest valley — up to statistical uncertainties. An ideal quality metric for the ground state problem would not only allow the user to benchmark different methods against the same problem, but also different target problems when tackled by the same method.

A research team led by National Tsing Hua University Department of Physics and Center for Quantum Science and Technology professor Chuu Chih-sung (褚志崧) has developed Taiwan’s first and the world’s smallest quantum computer, using a single photon, the university said yesterday.

The prediction that twisted semiconductor bilayers can host so-called non-Abelian states without a magnetic field holds promise for fault-tolerant quantum computing.

From subatomic particles to complex molecules, quantum systems hold the key to understanding how the universe works. But there’s a catch: when you try to model these systems, that complexity quickly spirals out of control—just imagine trying to predict the behavior of a massive crowd of people where everyone is constantly influencing everyone else. Turn those people into quantum particles, and you are now facing a “quantum many-body problem.”

Quantum defects have the potential to act as ultra-sensitive sensors that could offer new kinds of navigation or biological sensor technology.
