Cluster of Excellence MCQST
At MCQST, the “Cluster of Excellence Munich Center for Quantum Science and Technology,” we are interested in questions of quantum communication and quantum information theory, and are especially interested in models for analog quantum computing and Turing quantum computing.
In quantum communication and quantum information theory, we focus on:
- the characterization of channel capacities for transmission of quantum information with and without attackers
- the role of entanglement for classical and quantum communication
- finite block length performance for communication protocols
- resource theory for quantum communication networks
- computability of capacity formulas
In the areas of analog quantum computing and Turing quantum computing, we focus on:
- analog quantum computer models
- quantum Turing machines
- complexity blow-up behavior of Turing machines
- advantages of analog quantum computers for physical problems
- advantages of analog quantum computers for the calculation of performance parameters for quantum communication systems
On the homepage of the Munich Center for Quantum Science and Technology you will find all news and events.
Further information on the publications can also be found on the member page of Prof. Holger Boche at the MQCST.
