Quantum parameter estimation on coherently superposed noisy channels
Francois Chapeau-Blondeau
A generic qubit unitary operator affected by quantum noise is duplicated and inserted in a coherently superposed channel, superposing two paths offered to a probe qubit across the…

Noisy quantum metrology with the assistance of indefinite causal order
Francois Chapeau-Blondeau
A generic qubit unitary operator affected by depolarizing noise is duplicated and inserted in a quantum switch process realizing a superposition of causal orders. The characterizat…
