Error mitigation of shot-to-shot fluctuations in analog quantum simulators
Thomas Steckmann, De Luo, Yu-Xin Wang +7
Analog quantum simulators have provided key insights into quantum many-body dynamics. However, in such systems, both coherent and incoherent errors limit their scalability, hinderi…
Efficient quantum tomography of a polynomial subspace
Yat Wong, Ming Yuan, Kevin He +4
Quantum tomography is crucial for characterizing the quantum states of multipartite systems, but its practicality is often limited by the exponentially large dimension of the Hilbe…
Uncovering measurement-induced entanglement via directional adaptive dynamics and incomplete information
Yu-Xin Wang, Alireza Seif, Aashish A. Clerk
The rich entanglement dynamics and transitions exhibited by monitored quantum systems typically only exist in the conditional state, making observation extremely difficult. In this…
Exponential entanglement advantage in sensing correlated noise
Yu-Xin Wang, Jacob Bringewatt, Alireza Seif +3
In this work, we propose a new form of exponential quantum advantage in the context of sensing correlated noise. Specifically, we focus on the problem of estimating parameters asso…
Measurement and feedforward induced entanglement negativity transition
Alireza Seif, Yu-Xin Wang, Ramis Movassagh +1
We study the interplay between measurement-induced dynamics and conditional unitary evolution in quantum systems. We numerically and analytically investigate commuting random measu…
