The statistical disturbance bound of quantum measurements
Ties-A. Ohst, Sebastian Schlösser, Roope Uola
Quantifying the disturbance caused by a quantum measurement typically requires detailed knowledge of the underlying measurement channel. In this work, we introduce a statistical di…
Quantifying randomness with measurement incompatibility
Sebastian Schlösser, Pauli Jokinen, Martin Plávala +3
We present a trade-off between the amount of observed measurement incompatibility and the capabilities of a classical Eavesdropper in a prepare-and-measure scenario. The result is…
Simulating quantum measurements without superposition devices
Gabriele Cobucci, Alexander Bernal, Roope Uola +1
Superposition is the core feature that sets quantum theory apart from classical physics. Here, we investigate whether sets of quantum measurements can be modelled by using only dev…
Certification of the genuine resolution of photon number resolving detectors
Jef Pauwels, Towsif Taher, Roope Uola +3
Photon-number-resolving (PNR) detectors are essential components of photonic quantum technologies, yet thus far, no practical metric exists to certify how many photons they can gen…
High-Dimensional Quantum Photonics: Roadmap
Mehul Malik, Micheal Kues, Takuya Ikuta +30
The field of high-dimensional quantum photonics involves the use of multimode photonic degrees-of-freedom such as the spatial, temporal, or spectral structure of light to encode mu…
Can every set of incompatible measurements lead to genuine multipartite steering?
Lucas E. A. Porto, Lucas Tendick, Daniel Cavalcanti +2
Measurement incompatibility and bipartite quantum steering are known to display a strong connection: a set of measurements is incompatible if and only if it can lead to bipartite s…
