Advances in high-dimensional quantum entanglement

M Erhard, M Krenn, A Zeilinger - Nature Reviews Physics, 2020 - nature.com
Since its discovery, quantum entanglement has challenged some of the best established
views of the world: locality and reality. Quantum technologies promise to revolutionize …

Quantum indistinguishability by path identity and with undetected photons

A Hochrainer, M Lahiri, M Erhard, M Krenn… - Reviews of Modern …, 2022 - APS
Two processes of photon-pair creation can be arranged such that the paths of the emitted
photons are identical. The path information is thereby not erased but rather never born in the …

[BOOK][B] Geometry of quantum states: an introduction to quantum entanglement

I Bengtsson, K Życzkowski - 2017 - books.google.com
Quantum information theory is a branch of science at the frontier of physics, mathematics,
and information science, and offers a variety of solutions that are impossible using classical …

[BOOK][B] Holographic entanglement entropy

M Rangamani, T Takayanagi, M Rangamani… - 2017 - Springer
The discussions in § 2 and § 3 make it rather clear that while we have to evaluate a
sequence of functional integrals to compute the Rényi entropies, these are rather complex …

Computer-inspired quantum experiments

M Krenn, M Erhard, A Zeilinger - Nature Reviews Physics, 2020 - nature.com
The design of new devices and experiments has historically relied on the intuition of human
experts. Now, design inspirations from computers are increasingly augmenting the capability …

Holographic tensor network models and quantum error correction: a topical review

A Jahn, J Eisert - Quantum Science and Technology, 2021 - iopscience.iop.org
Recent progress in studies of holographic dualities, originally motivated by insights from
string theory, has led to a confluence with concepts and techniques from quantum …

From dual-unitary to quantum Bernoulli circuits: Role of the entangling power in constructing a quantum ergodic hierarchy

S Aravinda, SA Rather, A Lakshminarayan - Physical Review Research, 2021 - APS
Deterministic classical dynamical systems have an ergodic hierarchy, from ergodic through
mixing, to Bernoulli systems that are “as random as a coin toss.” Dual-unitary circuits have …

Thirty-six entangled officers of Euler: Quantum solution to a classically impossible problem

SA Rather, A Burchardt, W Bruzda… - Physical Review Letters, 2022 - APS
The negative solution to the famous problem of 36 officers of Euler implies that there are no
two orthogonal Latin squares of order six. We show that the problem has a solution …

Absolutely maximally entangled states of seven qubits do not exist

F Huber, O Gühne, J Siewert - Physical review letters, 2017 - APS
Pure multiparticle quantum states are called absolutely maximally entangled if all reduced
states obtained by tracing out at least half of the particles are maximally mixed. We provide a …

Five open problems in quantum information theory

P Horodecki, Ł Rudnicki, K Życzkowski - PRX Quantum, 2022 - APS
We identify five selected open problems in the theory of quantum information, which are
rather simple to formulate, are well studied in the literature, but are technically not easy. As …
