Hybrid Quantum-Classical Codes

2022-11-24
Date: 2022-11-28
Time: 14:15
Location: Quantum Chaos and Quantum Information (Jagiellonian University), Meeting id: 896 0129 1160
seminar
Speaker: Andrew Nemec (Duke University, USA) Abstract Hybrid codes simultaneously encode both quantum and classical information together, giving an advantage over coding schemes where the quantum and classical information are transmitted separately. We construct the first known families of hybrid codes that are guaranteed to provide an advantage over quantum codes, as well as also […]

Mutually unbiased measurements

2022-11-21
Date: 2022-11-23
Time: 12:30
Location: Center for Theoretical Physics Colloquium
seminar
Speaker: Máté Farkas (ICFO, Barcelona) Abstract Mutually unbiased bases (MUBs) correspond to measurements in quantum theory that are complementary: if a measurement in a basis yields a definite outcome on a given quantum state, then a measurement in a basis unbiased to the first one yields a uniformly random outcome on the same state. Simple […]

Graph Approach to Entanglement Generation in Linear Quantum Networks

2022-11-20
Date: 2022-11-23
Time: 14:00
Location: ICTQT, room 317
seminar
Speaker: Seungbeom Chin (ICTQT / Sungkyunkwan University) Abstract We propose a graph method to systematically search for schemes that obtains genuine entanglement in arbitrary N-partite linear quantum networks (LQNs). While the indistinguishability of quantum particles is widely used as a resource for the generation of entanglement, it is challenging to devise a suitable LQN that […]

All quantum spectra in one shot

2022-11-20
Date: 2022-11-23
Time: 12:30
Location: ICTQT, room 317
ICTQT Seminar
Speaker: Carlos L. Benavides-Riveros (MPI for the Physics of Complex Systems, Dresden / University of Trento) Abstract Determining the properties of the excitations in quantum many-body systems is a fundamental problem across almost all sciences. For instance, quantum excited states underpin new states of matter, support biological processes such as vision, or determine optoelectronic properties […]

Quantum Error Correction with Superconducting Transmon Qubits

2022-11-14
Date: 2022-11-16
Time: 15:30
Location: Team-Net Quantum Computing Colloquium
seminar
Speaker: Barbara Terhal (QuTech, TU Delft & Forschungszentrum Juelich) Abstract We review the goals of quantum error correction, in particular the use of the surface code. We discuss some of the results and challenges in experimental quantum error correction, in particular with respect to qubit leakage.

An elegant scheme of self-testing for multipartite Bell inequalities

2022-11-08
Date: 2022-11-10
Time: 12:00
Location: ICTQT, room 317
ICTQT Seminar
Speaker: Ekta Panwar (UG/ICTQT) Abstract The predictions of quantum theory are incompatible with local-causal explanations. This phenomenon is called Bell non-locality and is witnessed by the violation of Bell-inequalities. The maximal violation of certain Bell-inequalities can only be attained in an essentially unique manner. This feature is referred to as self-testing and constitutes the most […]
