Quantum computers work by applying quantum operations, such as quantum gates, to delicate quantum states. Ideally, quantum ...

In classical physics, memory is defined in a straightforward way. If a system’s future behavior depends only on its current condition, it is considered memoryless. If earlier states continue to ...

Researchers developed compilation-based quantum process tomography, a framework that reconstructs quantum operations using fewer measurements than conventional methods.

An international group of researchers have investigated the role of memory in quantum systems and dynamics. Their findings ...

Sometimes a visually compelling metaphor is all you need to get an otherwise complicated idea across. In the summer of 2001, a Tulane physics professor named John P.

In quantum information processing, encoding and processing high-dimensional quantum information could provide unique advantages, for example, stronger violation of Bell’s non-locality, quantum ...

Quantum computers can store more data and process specific computing tasks much faster than classical computers. However, they're also larger, pricier, and consume more power than their classical ...

A research team has developed a technology to precisely control the concentration of anion defects in eco-friendly quantum dots through joint research. Through this technology, the research team ...

A new class of quantum-engineered photocatalytic material can split ordinary water into clean hydrogen fuel using nothing but ...
