Quantum transfer of interacting and entangled qubits

Speaker: Adam Sawicki (CFT PAN, Warsaw) Abstract Universal quantum gates play a central role in quantum computing. It is well known that in order to construct a universal set of gates for many qudits it is enough to take a universal set for one qudit and extend it by a two-qudit entangling gate. On the […]

Speaker: Ravishankar Ramanathan (Hong Kong) Abstract Abstract: It is well known that classical tools do not allow the extraction of randomness from a single random source. On the other hand, quantum theory allows for such extraction even within the device-independent framework. While practically feasible protocols have been proposed for randomness sources that possess a specific […]

Speaker: Ingo Roth (Quantum research centre, Technology Innovation Institute, Abu Dhabi, UAE) Abstract Randomized benchmarking protocols have become the prominent tool for assessing the quality of gates on digital quantum computing platforms. In `classical’ variants of randomized benchmarking multi-qubit gates are drawn uniformly from a finite group. The functioning of such schemes can be rigorous […]

Speaker: Luis Pedro Garcia Pintos (Joint Quantum Institute and QuICS, University of Maryland) Abstract I will give an overview of recent bounds on the speed with which observables can evolve in quantum and classical systems. The bounds typically take the form of uncertainty relations that connect the maximum rate of change of an observable to […]

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 […]

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 […]
