Exploring Invisible New Physics with Exotic Pion Decays
Wolfgang Altmannshofer, Jeff A. Dror, Pierce Giffin +5
We study the sensitivity of past and future stopped-pion experiments to light, invisible dark sector particles produced in exotic pion decays. We consider two-body decays involving…
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…
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…
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…
Measurement Crosstalk Errors in Cloud-Based Quantum Computing
Seungchan Seo, Joonwoo Bae
Quantum technologies available currently contain noise in general, often dubbed noisy intermediate-scale quantum (NISQ) systems. We here present the verification of noise in measur…
Mitigation of Crosstalk Errors in Quantum Measurements
Seungchan Seo, Jiheon Seong, Huan-Yu Ku +1
In the present-day quantum information technologies, measurements are performed not only at the end of quantum state evolution but also between quantum circuits to connect short-de…
