Quantum computers—devices that process information using quantum mechanical effects—have long been expected to outperform classical systems on certain tasks. Over the past few decades, researchers ...

When a quantum computer processes data, it must translate it into understandable quantum data. Algorithms that carry out this 'quantum compilation' typically optimize one target at a time. However, a ...

Ewin Tang was only 18 when her research challenged a widely held belief about the power of quantum computing. As a University ...

The reliable engineering of quantum states, particularly those involving several particles, is central to the development of various quantum technologies, including quantum computers, sensors and ...

A team from Amazon Web Services, NVIDIA, Lawrence Berkeley National Laboratory, and NASA published a paper this week that settles one of the most expensive open questions in quantum computing ...

Quantum computing offers the hope of dramatic increases in computational capabilities. That’s the promise of quantum computers that can handle hundreds of thousands or millions of quantum bits or ...

A search problem refers to the task of finding a solution within some space of possible options, and that space could be made up of discrete steps or continuously varying values. For example, solving ...

There are many algorithms for which it has been mathematically proven that a quantum computer can generate results that would take a classical computer an unreasonable amount of time to generate.

Quantum computing has the potential to one day break today’s encryption algorithms, requiring a proactive approach to finding new and innovative ways to protect data that can withstand those upcoming ...
