Gate-error analysis in simulations of quantum computers with transmon qubits

Understand

In the model of gate-based quantum computation, the qubits are controlled by a sequence of quantum gates.

• In superconducting qubit systems, these gates can be implemented by voltage pulses.
• The success of implementing a particular gate can be expressed by various metrics such as the average gate fidelity, the diamond distance, and the unitarity.
• We analyze these metrics of gate pulses for a system of two superconducting transmon qubits coupled by a resonator, a system inspired by the architecture of the IBM Quantum Experience.
