Decoherence time measurement

There are different sources of decoherence[1] depending on the quantum device technology, but the decoherence mechanism can be distinguished in two parts : the relaxation time and the dephasing time. This module implements both relaxation and dephasing time measurement. Languages & Frameworks PyQuil Qiskit Q# Method The relaxation time T1 is the decay of a […]

Quantum device fidelity benchmark

Introduction Over last few years, we are facing a quantum computer race where the main challenge is to build efficient and reliable qubits. All players regularly announce their roadmap, a major breakthrough or quantum supremacy. One of the most important aspects is being able to characterize and measure the quality and fidelity of different quantum […]
