Framework of dynamical transitions from long-range to short-range quantum systems
Leela Ganesh Chandra Lakkaraju, Srijon Ghosh, Debasis Sadhukhan +1
A quantum many-body system undergoes phase transitions of distinct species with variations of local and global parameters. We propose a framework in which a dynamical quantity can…

Simplifying errors by symmetry and randomisation
James Mills, Debasis Sadhukhan, Elham Kashefi
We present a set of methods to generate less complex error channels by quantum circuit parallelisation. The resulting errors are simplified as a consequence of their symmetrisation…
