One of the major challenges of implementing high-rate quantum error correction codes, like qLDPC codes, is realizing the required long-range interactions. Spin qubit platforms can provide this connectivity by shuttling qubits next to each other whenever they need to interact. When doing this, the performance of the cod...

We give a quantum algorithm for stochastic $2$-player games. Their game trees are the expectiminimax trees of classical game search: $m$ adversarial layers alternate with $m$ chance layers, every node has $deg$ children, and the leaf values lie in an interval of length $N$. The algorithm estimates the value of the game...

We develop a general theory for the dynamics of the geodesic flow of locally CAT(k) branched coverings and we show that it does not depend on the specific covering but only on the base space, the branching set and the degree of the covering. We find an explicit formula for the entropy: it equals the topological pressur...
