The resource theory of tensor networks
Matthias Christandl, Vladimir Lysikov, Vincent Steffan +2
Tensor networks provide succinct representations of quantum many-body states and are an important computational tool for strongly correlated quantum systems. Their expressive and c…
Fault-tolerant Coding for Quantum Communication
Matthias Christandl, Alexander Müller-Hermes
Designing encoding and decoding circuits to reliably send messages over many uses of a noisy channel is a central problem in communication theory. When studying the optimal transmi…
More quantum chemistry with fewer qubits
Jakob Günther, Alberto Baiardi, Markus Reiher +1
Quantum computation is one of the most promising new paradigms for the simulation of physical systems composed of electrons and atomic nuclei, with applications in chemistry, solid…
Going Beyond Gadgets: The Importance of Scalability for Analogue Quantum Simulators
Dylan Harley, Ishaun Datta, Frederik Ravn Klausen +4
Quantum hardware has the potential to efficiently solve computationally difficult problems in physics and chemistry to reap enormous practical rewards. Analogue quantum simulation…
Fault-tolerant Coding for Entanglement-Assisted Communication
Paula Belzig, Matthias Christandl, Alexander Müller-Hermes
Channel capacities quantify the optimal rates of sending information reliably over noisy channels. Usually, the study of capacities assumes that the circuits which sender and recei…
