A quantum computer is a computer that exploits quantum mechanical phenomena. On small scales, physical matter exhibits properties of both particles and waves, and quantum computing leverages this behavior using specialized hardware.

2024年8月5日 · Quantum computing is an emergent field of cutting-edge computer science harnessing the unique qualities of quantum mechanics to solve problems beyond the ability of even the most powerful classical computers. The field of quantum computing contains a range of disciplines, including quantum hardware and quantum algorithms.

2019年1月29日 · Quantum computers harness entangled qubits in a kind of quantum daisy chain to work their magic. The machines’ ability to speed up calculations using specially designed quantum algorithms is...

Quantum computing holds the promise of solving some of our planet's biggest challenges - in the areas of environment, agriculture, health, energy, climate, materials science, and more. For some of these problems, classical computing is increasingly challenged as the size of the system grows.

2024年11月1日 · Technology companies are pouring billions of dollars into quantum computing, despite the technology still being years away from practical applications. So what will future quantum computers...

2023年5月9日 · Have you ever heard of a computer that can do things regular computers can’t? These special computers are called quantum computers. They are different from the computer you use at home or school because they use something called “qubits” instead of regular “bits”. A bit is like a light switch that can only be on or off, like a zero or a one.

2022年7月6日 · Quantum computing is the practice of harnessing those properties to enable revolutionary algorithms that traditional computers wouldn’t be able to run. Algorithms are a set of instructions to solve a problem or accomplish a task in computing.

Quantum computers share some properties with classical ones. For example, both types of computers usually have chips, circuits, and logic gates. Their operations are directed by algorithms (essentially sequential instructions), and they use a binary code of ones and zeros to represent information.
