On sequential measurements with indefinite causal order

Masashi Ban

Summary: This study examines two projective measurements performed sequentially on a quantum system with completely indefinite order. The interference of different orders allows for the determination of the Kirkwood-Dirac distribution of the quantum system being measured, enabling the extraction of a weak value of an observable without the need for weak measurement. In an interferometric setting, the Kirkwood-Dirac distribution can be constructed from conditional visibility and phase shift.

Non-classicality created by quantum channels with indefinite causal order

Summary: The non-classicality of output states of quantum channels with indefinite causal order is studied, showing that thermalizing channels can create non-classicality even with classical input states.

Quantum parameter estimation on coherently superposed noisy channels

Francois Chapeau-Blondeau

Summary: This study discusses a generic qubit unitary operator affected by quantum noise and analyzes the performance of a coherently superposed channel for phase estimation of the noisy unitary. It is found that the control qubit of the superposed channel can be measured alone for effective estimation, even without direct interaction with the unitary being estimated. Additionally, the noise plays a crucial role in coupling the control qubit to the unitary, enabling phase estimation even in strong noise conditions where conventional techniques fail.

Noisy quantum metrology with the assistance of indefinite causal order

Francois Chapeau-Blondeau

Summary: This study investigates the superposition of causal orders by duplicating a generic qubit unitary operator affected by depolarizing noise in a quantum switch process. The switched quantum channel's characterization for its action on the joint state of the probe-control qubit pair is explored, specifically focusing on phase estimation on the noisy unitary operator. The results show that measuring the control qubit in the switched channel can lead to effective estimation, even in challenging conditions where traditional estimation methods fail.
