Noise-robust 1-copy distillation protocol for all distillable Bell-diagonal qutrits
Tobias C. Sutter, Christopher Popp, Beatrix C. Hiesmayr
Entanglement distillation is the process of converting noisy entangled states into maximally entangled pure states via local operations and classical communication. A long-standing…
Resource State Distillation via Stabilizer Channels
Christopher Popp, Tobias C. Sutter, Beatrix C. Hiesmayr
Quantum technologies rely on high-quality resource states, such as maximally entangled or private states, which are indispensable for quantum communication and cryptography. In pra…
Looking through the Kerr disk
Maciej Maliborski, Tobias C. Sutter
We study null geodesics that connect the two asymptotically flat regions of the maximally extended Kerr spacetime. These vortical geodesics traverse both horizons and pass through…
Computation of the Smooth Max-Mutual Information via Semidefinite Programming
Christopher Popp, Tobias C. Sutter, Beatrix C. Hiesmayr
We present an iterative algorithm based on semidefinite programming (SDP) for computing the quantum smooth max-mutual information of bipartite quantu…
Local Invariance of Divergence-based Quantum Information Measures
Christopher Popp, Tobias C. Sutter, Beatrix C. Hiesmayr
Quantum information quantities, such as mutual information and entropies, are essential for characterizing quantum systems and protocols in quantum information science. In this con…
Bridging Quantum Noise and Classical Electrodynamics with Stochastic Methods
Felix Hitzelhammer, Johannes Stowasser, Lukas Hanschke +7
The development of emerging technologies in quantum optics demands accurate models that faithfully capture genuine quantum effects. Mature semiclassical approaches reach their limi…
Group-Theoretic Perspective on the PPT and Realignment Criteria in the Magic Simplex for Bipartite Qutrits
Tobias C. Sutter, Christopher Popp, Beatrix C. Hiesmayr
Entanglement is a key feature in many quantum technologies, including secure communication protocols and quantum computing. However, detecting it in mixed quantum states remains a…
The Impact of Architecture and Cost Function on Dissipative Quantum Neural Networks
Tobias C. Sutter, Christopher Popp, Beatrix C. Hiesmayr
Combining machine learning and quantum computation is a potential path towards powerful applications on quantum devices. Regarding this, quantum neural networks are a prominent app…
Low-Fidelity Entanglement Distillation with FIMAX
Christopher Popp, Tobias C. Sutter, Beatrix C. Hiesmayr
Uncontrolled interactions with the environment introduce errors that remain a significant challenge to the reliability of quantum technologies using entanglement. An essential meth…
A Novel Stabilizer-based Entanglement Distillation Protocol for Qudits
Christopher Popp, Tobias C. Sutter, Beatrix C. Hiesmayr
Entanglement distillation, the process of converting weakly entangled states into maximally entangled ones using Local Operations and Classical Communication (LOCC), is pivotal for…
