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…
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…
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…
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…
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…
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 quant…
