Uncountably many inequivalent maximally entangled measurements for two qutrits
Elna Svegborn, Jef Pauwels, Nicolas Gisin +1
Every two-qubit measurement basis composed of maximally entangled eigenstates can be transformed into the Bell basis via local unitary operations. For higher dimensions, in contras…
Faking entanglement with imperceptible measurement deviations
Jaime Moreno, Elna Svegborn, Simon Morelli +4
Quantum entanglement is a central resource underpinning emerging quantum technologies, enabling capabilities beyond those of classical systems. Accurate verification of entanglemen…
Entanglement in prepare-and-measure scenarios without receiver inputs
Elna Svegborn, Armin Tavakoli
The most elementary prepare-and-measure scenarios have no independent measurement inputs. No inputs mean that quantum advantages require two indispensable ingredients: shared entan…
Framework for (non-)adiabatic chiral state conversion: from non-Hermitian Hamiltonians to Liouvillians
Elna Svegborn, Shishir Khandelwal
Adiabatic chiral state conversion (CSC) is one of the many counterintuitive effects associated with non-Hermitian physics. In quantum systems, numerous works have demonstrated this…
Binarisation-loophole-free observation of high-dimensional quantum nonlocality
Jia-le Miao, Elna Svegborn, Zhuo Chen +7
Bell inequality tests based on high-dimensional entanglement usually require measurements that can resolve multiple possible outcomes. However, the implementation of high-dimension…
Quantum inputs in the prepare-and-measure scenario and stochastic teleportation
Elna Svegborn, Jef Pauwels, Armin Tavakoli
We investigate prepare-and-measure scenarios in which a sender and a receiver use entanglement to send quantum information over a channel with limited capacity. We formalise this f…
Imprecision plateaus in quantum steering
Elna Svegborn, Nicola d'Alessandro, Otfried Gühne +1
We study tests of quantum steering in which the trusted party does not have perfect control of their measurements. We report on steering inequalities that remain unaffected when in…
Mollow-like triplets in ultra-fast resonant absorption
Axel Stenquist, Felipe Zapata, Edvin Olofsson +5
We show that resonant absorption of smooth laser fields can yield Mollow-like triplet patterns. General conditions for such triplets are derived and illustrated with a super-Gaussi…
