Semi-Device-Independent Certification for Nonlocality without Entanglement
Hanwool Lee, Joonwoo Bae
In this work, we present the framework for demonstrating and certifying the distinction between measurements in an entangled basis, called global measurements, and local operations…
Measurement circuit ansatz: Naimark versus quantum neural-network measurements
Sung Won Yun, Thi Ha Kyaw, Joonwoo Bae
In this work, we present constructions of quantum circuits to implement general measurements on quantum hardware. Firstly, we investigate a quantum circuit ansatz by following the…
Practical and Efficient Verification of Entanglement with Incomplete Measurement Settings
Jiheon Seong, Jin-Woo Kim, Seungchan Seo +6
In this work, we present a practical and efficient framework for verifying entangled states when only a tomographically incomplete measurement setting is available-specifically, wh…
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…
Carrier-Assisted Entanglement Purification
Jaemin Kim, Karthik Mohan, Sung Won Yun +1
Entanglement distillation, a fundamental building block of quantum networks, enables the purification of noisy entangled states shared among distant nodes by local operations and c…
Protocol for Purifying Noisy Preparation and Measurements of Qubits
Jaemin Kim, Seungchan Seo, Jiyoung Yun +2
Noise affecting qubit preparation and measurements accounts for a significant fraction of errors in quantum information processing. This is especially critical in tasks like variat…
A mirrored pair of optimal non-decomposable entanglement witnesses for two qudits does exist
Dariusz Chruściński, Anindita Bera, Joonwoo Bae +1
Two approaches can be utilized to handle the separability problem, finding out whether a given bipartite qudit state is separable or not: a direct procedure on the state space or t…
Machine-learning certification of multipartite entanglement for noisy quantum hardware
Andreas J. C. Fuchs, Eric Brunner, Jiheon Seong +5
Entanglement is a fundamental aspect of quantum physics, both conceptually and for its many applications. Classifying an arbitrary multipartite state as entangled or separable -- a…
Static Quantum Errors and Purification
Jaemin Kim, Seungchan Seo, Jiyoung Yun +1
State preparation that initializes quantum systems in a fiducial state and measurements to read outcomes after the evolution of quantum states, both essential elements in quantum i…
Purification of Noisy Measurements and Faithful Distillation of Entanglement
Jaemin Kim, Jiyoung Yun, Joonwoo Bae
We consider entanglement distillation with noisy operations in which quantum measurements that constitute a general quantum operation are particularly noisy. We present a protocol…
Detecting Entanglement by State Preparation and Local Measurements
Jaemin Kim, Anindita Bera, Dariusz Chruściński +1
Entanglement witnesses (EWs) are a collection of observables that can characterize separable states and, experimentally, estimating EWs can verify entangled states. In this work, w…
Quantum Advantages in (n,d)->1 Random Access Codes
Andris Ambainis, Dmitry Kravchenko, Sk Sazim +2
A random access code (RAC), corresponding to a communication primitive with various applications in quantum information theory, is an instance of a preparation-and-measurement scen…
