All realistic quantum systems interact with their environments and thereby must be considered as open quantum systems. When a quantum system is strongly coupled to its environment, the so-called ...

Quantum control of linear stochastic systems encompasses the rigorous study of controlling quantum devices whose dynamics are inherently influenced by random fluctuations. These systems are described ...

Experimental physicist David Weld’s experimental research interest lies in a question that has been around for a long time, but which we’re only now approaching the ability to investigate. “There’s a ...

Interdisciplinary teams across the Quantum Systems Accelerator (QSA) are using innovative approaches to push the boundaries of superconducting qubit technology, bridging the gap between today's NISQ ...

Origin Wukong’s developers, Origin Quantum Computing Technology Co., launched China’s fourth-generation self-developed quantum control system supporting over 500 qubits. Named Origin Tianji 4.0, this ...

SANTA ROSA, Calif.--(BUSINESS WIRE)--Keysight Technologies, Inc. (NYSE: KEYS) has delivered the world’s largest 1 commercial quantum control system (QCS) to the National Institute of Advanced ...

Quantum computers can solve certain computational problems much faster than ordinary computers by using specific quantum properties. The basic building blocks of such machines are called quantum-bits ...

The path toward realizing practical quantum technologies begins with understanding the fundamental physics that govern ...

Every second of modern life runs on precision — from GPS navigation to the time signals that keep the internet in sync. But ...

This illustration draws a parallel between quantum state tomography and natural language modeling. In quantum tomography, structured measurements yield probability outcomes that are aggregated to ...

Imagine a physicist observing a quantum system whose behavior is akin to a coin toss: it could come up heads or tails. They perform the quantum coin toss and see heads. Could they be certain that ...

Compared to scribbling mathematical expressions for entangled quantum states on a sheet of paper, producing real entanglement is a tricky task. In the lab, physicists can only claim a prepared quantum ...
