Quadratic fermionic interactions yield effective Hamiltonians for adiabatic quantum computing
Michael J. O'Hara, Dianne P. O'Leary
Polynomially-large ground-state energy gaps are rare in many-body quantum systems, but useful for adiabatic quantum computing. We show analytically that the gap is generically poly…

The adiabatic theorem in the presence of noise
Michael J. O'Hara, Dianne P. O'Leary
We provide rigorous bounds for the error of the adiabatic approximation of quantum mechanics under four sources of experimental error: perturbations in the initial condition, syste…
