Quantum computers promise enormous computational power, but the nature of quantum states makes computation and data ...

A device made from superconducting qubits could prove a powerful technology for enabling practical quantum computing or more ...

Quantum computers are designed to outperform standard computers by running quantum algorithms. Areas in which quantum algorithms can be applied include cryptography, search and optimisation ...

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 ...

Scientists have taken a major step toward building large-scale quantum computers by successfully linking two separate quantum processors into a single, fully connected system. This breakthrough in ...

Twenty years ago, theoretical physicists and computer scientists were developing quantum algorithms for virtual quantum computers, with no working hardware in sight. Today, just about anyone can log ...

Since the 1990s, evidence has been growing that quantum computers should be able to solve a range of particularly complex ...

For problems suited to specific algorithms where quantum calculations offer advantages, that system would tap its quantum accelerator chip.

One notable example is the $34 million secured by British quantum algorithms specialist Phasecraft from a group of investors, ...

One of the ways that computers 'think' is by analyzing relationships within large sets of data. An international team has shown that quantum computers can do one such analysis faster than classical ...
