Graphical Structures for Design and Verification of Quantum Error Correction
Nicholas Chancellor, Aleks Kissinger, Joschka Roffe +2
We introduce a high-level graphical framework for designing and analysing quantum error correcting codes, centred on what we term the coherent parity check (CPC). The graphical for…
Quantum common causes and quantum causal models
John-Mark A. Allen, Jonathan Barrett, Dominic C. Horsman +2
Reichenbach's principle asserts that if two observed variables are found to be correlated, then there should be a causal explanation of these correlations. Furthermore, if the expl…
Can a quantum state over time resemble a quantum state at a single time?
Dominic Horsman, Chris Heunen, Matthew F. Pusey +2
Standard quantum theory represents a composite system at a given time by a joint state, but it does not prescribe a joint state for a composite of systems at different times. If a…
Surface Code Error Correction on a Defective Lattice
Shota Nagayama, Austin G. Fowler, Dominic Horsman +2
The yield of physical qubits fabricated in the laboratory is much lower than that of classical transistors in production semiconductor fabrication. Actual implementations of quantu…
Proceedings of the 7th International Workshop on Physics and Computation
Alastair A. Abbott, Dominic C. Horsman
This volume constitutes the proceedings of the 7th International Workshop on Physics and Computation (PC 2016). The workshop was held on the 14th of July 2016 in Manchester, UK, as…
