Entanglement Enhanced Sensing with Qubits affected by non-Markovian Dephasing
Noah Kaufmann, Kasper H. Nielsen, Eva M. González-Ruiz +1
Entanglement has been proposed as a means to improve the sensitivity of sensing weak signals. While the degree of this quantum advantage is well understood in noiseless settings, t…

Estimating Bell Diagonal states with separable measurements
Noah Kaufmann, Maria Quadeer, David Elkouss
Quantum network protocols depend on the availability of shared entanglement. Given that entanglement generation and distribution are affected by noise, characterization of the shar…

Characterization of coherent errors in gate layers with robustness to Pauli noise
Noah Kaufmann, Ivan Rojkov, Florentin Reiter
Characterization of quantum devices generates insights into their sources of disturbances. State-of-the-art characterization protocols often focus on incoherent noise and eliminate…
