Quantum Error Correcting Codes in Eigenstates of Translation-Invariant Spin Chains
Fernando G. S. L. Brandao, Elizabeth Crosson, M. Burak Şahinoğlu +1
Quantum error correction was invented to allow for fault-tolerant quantum computation. Systems with topological order turned out to give a natural physical realization of quantum e…
Quantum ground state isoperimetric inequalities for the energy spectrum of local Hamiltonians
Elizabeth Crosson, John Bowen
We investigate the relationship between the energy spectrum of a local Hamiltonian and the geometric properties of its ground state. By generalizing a standard framework from the a…
On Calculating the Dynamics of Very Large Quantum Systems
J. J. Bowen, V. M. Dwyer, I. W. Phillips +1
Due to the exponential growth of the state space of coupled quantum systems it is not possible, in general, to numerically store the state of a very large number of quantum systems…
