Childs, Nathan Wiebe. (Submitted on 27 Feb 2012) We present a new approach to simulating Hamiltonian dynamics based on implementing linear combinations of unitary operations rather than products of unitary operations. The resulting algorithm has superior performance to existing simulation algorithms based on …
Nettet11. sep. 2024 · We have studied the local unitary equivalence of quantum states in terms of invariants. In bipartite system, we expand quantum states in Bloch representation first. Then some invariants under local unitary transformation are constructed by the products of coefficient matrices, the singular values of coefficient matrix and the determinant of ...
