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…
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…
Mirrored Entanglement Witnesses for Multipartite and High-Dimensional Quantum Systems
Jiheon Seong, Anindita Bera, Beatrix C. Hiesmayr +2
Entanglement witnesses (EWs) are a versatile tool to detect entangled states and characterize related properties of entanglement in quantum information theory. A witness corres…
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…
