Right now, quantum computers are small and error-prone compared to where they’ll likely be in a few years. Even within those limitations, however, there have been regular claims that the hardware can ...

As quantum computing develops, scientists are working to identify tasks for which quantum computers have a clear advantage over classical computers. So far, researchers have only pinpointed a handful ...

Predicting the behavior of many interacting quantum particles is a complicated process but is key to harness quantum computing for real-world applications. Researchers have developed a method for ...

Quantum states are notoriously fragile, and can be destroyed simply through interactions, measurements, and exposure to their ...

A couple of weeks ago, the APS's Physics ran a piece titled Traveling with a Quantum Salesman, about a quantum computing approach to the famous "Traveling Salesman" problem. I saw the headline, and ...

Simulations of quantum many-body systems are an important goal for nuclear and high-energy physics. Many-body problems involve systems that consist of many microscopic particles interacting at the ...

A team of physicists from the University at Buffalo has developed a user-friendly method that allows researchers to solve complex quantum problems, once thought to require massive supercomputers, on ...

Scientists have found a new way to create a crystalline structure called a 'density wave' in an atomic gas. The findings can help us better understand the behavior of quantum matter, one of the most ...

Quantum computers are fragile miracles of physics that are unreliable, cost-prohibitive, and more error-prone than a shortstop with no depth perception. But, if we ever want to get to Star Trek levels ...
