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).

The IBM staff are building on a concept called circuit depth. Circuit depth starts with the idea that, because quantum gates can always introduce an error, there is a maximum number of operations ...

A new quantum computing benchmark has revealed ... that act on two entangled qubits simultaneously, and depth measures the length of a circuit – in other words, its complexity and execution ...

that’s “depth,” and today’s systems are considered shallow. Science today published a paper (“Quantum advantage with shallow circuits”) by Sergey Bravyi of IBM Research, David Gosset ...

Typical superconducting quantum circuits, such as qubits—basic processing units of a quantum computer, must be operated at very low temperatures, of a few 10s of millikelvin, or hundredths of a ...
