Non-Markovian Quantum Gate Set Tomography

Understand

Engineering quantum devices requires reliable characterization of the quantum system, including qubits, quantum operations (also known as instruments) and the quantum noise.

• Recently, quantum gate set tomography (GST) has emerged as a powerful technique for self-consistently describing quantum states, gates, and measurements.
• However, non-Markovian correlations between the quantum system and environment impact the reliability of GST.
• To address this, we propose a self-consistent operational framework called instrument set tomography (IST) for non-Markovian GST.
