Error-detected surgery on Iceberg codes
Andrea Di Fini, Samuel Crew, Laura Pecorari +1
We construct explicit error-detecting surgery gadgets---small systems of auxiliary qubits and checks---for the high-rate Iceberg codes , to perform fault-detected me…
Topological Recursion and Quantum Path Signatures
Inês Aniceto, Inês Aniceto, Thomas Cass +1
We introduce a non-commutative Laplace transform between functionals on path space and formal series in a tensor algebra, under which a natural convolution of path functionals beco…
Resurgence and Hyperasymptotics in Wave Optics Astronomy
Job Feldbrugge, Samuel Crew, Ue-Li Pen
With the discovery of gravitational waves and fast radio bursts, wave optics has become increasingly relevant in astrophysics. This paper studies the behaviour of random gravitatio…
Quantum Path Signatures
Samuel Crew, Cristopher Salvi, William F. Turner +2
We elucidate physical aspects of path signatures by formulating randomised path developments within the framework of matrix models in quantum field theory. Using tools from physics…
