What I am looking at is not just the most powerful computer in the world, but the key to financial security, Bitcoin, ...

Amid some scepticism, many say the machines can now achieve results beyond the capability of traditional computers ...

Paradoxically, reports of powerful quantum computations are motivating improvements to classical ones, making it harder for quantum machines to gain an advantage. “Most of the time when people talk ...

A gold superconducting quantum computer hangs against a black background. Quantum computers, like the one shown here, could someday allow chemists to solve problems that classical computers can’t.

Quantum computing promises extraordinary power, but that same power may expose new security weaknesses. Quantum computers are expected to deliver dramatic gains in processing speed and capability, ...

Alphabet generated $73.5 billion in free cash flow over the last 12 months. Committing even $1 billion per year to quantum ...

Using a powerful machine made up of 56 trapped-ion quantum bits, or qubits, researchers have achieved something once thought impossible. They have proven, for the first time, that a quantum computer ...

Mikel Díez, Director of Quantum Computing at IBM Spain, explains how the new quantum systems will work alongside classical ones to offer new possibilities for problem-solving. The Basque city of San ...
