Scalable Quantum Simulation of Molecular Energies
P. J. J. O'Malley, R. Babbush, I. D. Kivlichan +27
We report the first electronic structure calculation performed on a quantum computer without exponentially costly precompilation. We use a programmable array of superconducting qub…
Digitized adiabatic quantum computing with a superconducting circuit
R. Barends, A. Shabani, L. Lamata +26
A major challenge in quantum computing is to solve general problems with limited physical hardware. Here, we implement digitized adiabatic quantum computing, combining the generali…
The theory of variational hybrid quantum-classical algorithms
Jarrod R. McClean, Jonathan Romero, Ryan Babbush +1
Many quantum algorithms have daunting resource requirements when compared to what is available today. To address this discrepancy, a quantum-classical hybrid optimization scheme kn…
Exponentially More Precise Quantum Simulation of Fermions in the Configuration Interaction Representation
Ryan Babbush, Dominic W. Berry, Yuval R. Sanders +5
We present a quantum algorithm for the simulation of molecular systems that is asymptotically more efficient than all previous algorithms in the literature in terms of the main pro…
Exponentially more precise quantum simulation of fermions I: Quantum chemistry in second quantization
Ryan Babbush, Dominic W. Berry, Ian D. Kivlichan +3
We introduce novel algorithms for the quantum simulation of molecular systems which are asymptotically more efficient than those based on the Trotter-Suzuki decomposition. We prese…
