The operation of quantum computers, systems that process information leveraging quantum mechanical effects, relies on the implementation of quantum logic gates. These are essentially operations that ...

Quantum computers, systems that process information using the principles of quantum mechanics, could solve some problems that cannot be tackled by the classical computers currently used worldwide.

Quantum walks sound abstract, but they sit at the center of a very concrete race: who will harness quantum mechanics to solve problems that overwhelm today’s most powerful supercomputers. Instead of ...

Quantum computers hold the potential of solving some optimization and data processing problems that cannot be tackled by classical computers. Many of the most promising quantum computing platforms ...

A research team has created a quantum logic gate that uses fewer qubits by encoding them with the powerful GKP error-correction code. By entangling quantum vibrations inside a single atom, they ...

IBM and collaborators say their quantum computers outperform all known classical algorithms for three distinct tasks, but ...

Quantum computing is one of those technologies where real-world applications always seem to lie just over the horizon. The next big thing is announced before quickly becoming a forgotten article from ...

In a laboratory in Broomfield, Colorado, 98 atoms are suspended in mid-air, held in place by electric fields and cooled to temperatures close to absolute zero. Each atom is far smaller than anything ...
