Researchers have developed a new protocol for benchmarking quantum gates, a critical step toward realizing the full potential of quantum computing and potentially accelerating progress toward ...

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.

Researchers have succeeded in building a quantum computer gate based on a double-transmon coupler (DTC), which had been proposed theoretically as a device that could significantly enhance the fidelity ...

Quantum computing is in its infancy, but its potential has sparked intense exploration. This article examines three major trajectories that will shape the future of quantum computing: the gate-based ...

A quantum logic gate is a basic quantum device that operates on a small number of quantum bits or qubits. A unitary matrix -- a square matrix of complex numbers -- represents the quantum gate. A 2nx2n ...

D-Wave, a company long associated with a distinctive approach to quantum computing, has reported achieving a fast, high-fidelity quantum gate, a result described as a milestone for the technology. In ...
