Characterizing entanglement dimensionality from randomized measurements
Shuheng Liu, Qiongyi He, Marcus Huber +2
We consider the problem of detecting the dimensionality of entanglement with the use of correlations between measurements in randomized directions. First, exploiting the recently d…
Quantum key distribution rates from semidefinite programming
Mateus Araújo, Marcus Huber, Miguel Navascués +2
Computing the key rate in quantum key distribution (QKD) protocols is a long standing challenge. Analytical methods are limited to a handful of protocols with highly symmetric meas…
On the role of entanglement in qudit-based circuit compression
Xiaoqin Gao, Paul Appel, Nicolai Friis +2
Gate-based universal quantum computation is formulated in terms of two types of operations: local single-qubit gates, which are typically easily implementable, and two-qubit entang…
Simultaneous transmission of hyper-entanglement in 3 degrees of freedom through a multicore fiber
Lukas Achatz, Lukas Bulla, Evelyn A. Ortega +5
Entanglement distribution is at the heart of most quantum communication protocols. Inevitable loss of photons along quantum channels is a major obstacle for distributing entangled…
Bounding entanglement dimensionality from the covariance matrix
Shuheng Liu, Matteo Fadel, Qiongyi He +2
High-dimensional entanglement has been identified as an important resource in quantum information processing, and also as a main obstacle for simulating quantum systems. Its certif…
Native qudit entanglement in a trapped ion quantum processor
Pavel Hrmo, Benjamin Wilhelm, Lukas Gerster +6
Quantum information carriers, just like most physical systems, naturally occupy high-dimensional Hilbert spaces. Instead of restricting them to a two-level subspace, these high-dim…
