dc.description.abstract | The shift of interest from general purpose quantum computers to adiabatic quantum computing or
quantum annealing calls for a broadly applicable and easy to implement test to assess how quantum or
adiabatic is a specific hardware. Here we propose such a test based on an exactly solvable many body
system–the quantum Ising chain in transverse field–and implement it on the D-Wave machine. An ideal
adiabatic quench of the quantum Ising chain should lead to an ordered broken symmetry ground state
with all spins aligned in the same direction. An actual quench can be imperfect due to decoherence,
noise, flaws in the implemented Hamiltonian, or simply too fast to be adiabatic. Imperfections result
in topological defects: Spins change orientation, kinks punctuating ordered sections of the chain. The
number of such defects quantifies the extent by which the quantum computer misses the ground state,
and is, therefore, imperfect. | pl_PL |
