Quantum Error Mitigated Classical Shadows
Hamza Jnane, Jonathan Steinberg, Zhenyu Cai +2
Classical shadows enable us to learn many properties of a quantum state with very few measurements. However, near-term and early fault-tolerant quantum computers will only be a…
Certifying the activation of Bell nonlocality with finite data
Jonathan Steinberg, H. Chau Nguyen, Matthias Kleinmann
The activation of Bell nonlocality is a protocol that enables the violation of a Bell inequality from a system that initially did not allow for any such violation because the state…
Finding maximal quantum resources
Jonathan Steinberg, Otfried Gühne
For many applications the presence of a quantum advantage crucially depends on the availability of resourceful states. Although the resource typically depends on the particular tas…
Optimising shadow tomography with generalised measurements
H. Chau Nguyen, Jan Lennart Bönsel, Jonathan Steinberg +1
Advances in quantum technology require scalable techniques to efficiently extract information from a quantum system, such as expectation values of observables or its entropy. Tradi…
Graph-theoretic approach to Bell experiments with low detection efficiency
Zhen-Peng Xu, Jonathan Steinberg, Jaskaran Singh +3
Bell inequality tests where the detection efficiency is below a certain threshold can be simulated with local hidden-variable models. Here, we introduce a method to…
