The number of qubits and the number of operations that can be performed are called the width and depth of a quantum circuit. The deeper the circuit, the more complex of an algorithm the computer ...

In the language of quantum circuits, the computational model favored by most industry leaders, these characteristics can be described as width and depth (more specifically achievable circuit depth).

Quantum Art a developer of full-stack quantum computers, has integrated Nvidia's CUDA-Q hybrid quantum-classical platform ...

The other half of the proof provided by the researchers is showing that, contrary to a quantum circuit, any classical circuit needs to increase its depth as the number of inputs grows. For example ...

(Computational depth is the number of operations that a gate can perform before the qubit state is randomized due to environmental noise.) But there is a catch here. Although the quantum circuit ...
