Decoherence times of universal two-qubit gates in the presence of broad-band noise
E. Paladino, A. D'Arrigo, A. Mastellone +1
The controlled generation of entangled states of two quantum bits is a fundamental step toward the implementation of a quantum information processor. In nano-devices this operation…
Broadband noise decoherence in solid-state complex architectures
E Paladino, A D'Arrigo, A Mastellone +1
Broadband noise represents a severe limitation towards the implementation of a solid-state quantum information processor. Considering common spectral forms, we propose a classifica…
Optimal tuning of solid-state quantum gates: A universal two-qubit gate
E. Paladino, A. Mastellone, A. D'Arrigo +1
We present a general route to reduce inhomogeneous broadening in nanodevices due to 1/f noise. We apply this method to a universal two-qubit gate and demonstrate that for selected…
Effects of low-frequency noise cross-correlations in coupled superconducting qubits
A. D'Arrigo, A. Mastellone, E. Paladino +1
We study the effects of correlated low frequency noise sources acting on a two qubit gate in a fixed coupling scheme. A phenomenological model for the spatial and cross-talk correl…
Mesoscopic BCS pairing in the repulsive 1d-Hubbard model
Luigi Amico, Andrea Mastellone, Andreas Osterloh
We study mesoscopic pairing in the one dimensional repulsive Hubbard model and its interplay with the BCS model in the canonical ensemble. The key tool is comparing the Bethe ansat…
Initial decoherence in solid state qubits
G. Falci, A. D'Arrigo, A. Mastellone +1
We study decoherence due to low frequency noise in Josephson qubits. Non-Markovian classical noise due to switching impurities determines inhomogeneous broadening of the signal. Th…
