Impact of decoherence on the fidelity of quantum gates leaving the computational subspace
Tahereh Abad, Yoni Schattner, Anton Frisk Kockum +1
The fidelity of quantum operations is often limited by incoherent errors, which typically can be modeled by fundamental Markovian noise processes such as amplitude damping and deph…
The Wiedemann-Franz law in doped Mott insulators without quasiparticles
