Researchers have successfully used a quantum algorithm to solve a complex century-old mathematical problem long considered ...

Scientists have finally unlocked a way to identify the elusive W state of quantum entanglement, solving a decades-old problem ...

In theory, quantum physics can bypass the hard mathematical problems at the root of modern encryption. A new proof shows how.

Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex ...

The concept of quantum entanglement is emblematic of the gap between classical and quantum physics. Referring to a situation ...

For many business leaders, quantum computing feels like science fiction—a technology that’s exciting, but distant. That’s a ...

Traditional computers rely on binary bits for computation, while quantum computers utilize quantum bits that have superposition properties. The research team chose atoms as carriers for quantum bits ...

Strongly interacting systems play an important role in quantum physics and quantum chemistry. Stochastic methods such as Monte Carlo simulations are a proven method for investigating such systems.

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 ...

Matter gets weird at the quantum scale, and among the oddities is the Efimov effect, a state in which the attractive forces ...

The potentially worldchanging (if successful) test of a quantum drive in orbit is being delayed by rare and infrequent ...
