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…
Measuring and Suppressing Quantum State Leakage in a Superconducting Qubit
Zijun Chen, Julian Kelly, Chris Quintana +20
Leakage errors occur when a quantum system leaves the two-level qubit subspace. Reducing these errors is critically important for quantum error correction to be viable. To quantify…
Preserving entanglement during weak measurement demonstrated with a violation of the Bell-Leggett-Garg inequality
T. C. White, J. Y. Mutus, J. Dressel +18
Weak measurement has provided new insight into the nature of quantum measurement, by demonstrating the ability to extract average state information without fully projecting the sys…
Traveling wave parametric amplifier with Josephson junctions using minimal resonator phase matching
T. C. White, J. Y. Mutus, I. -C. Hoi +18
Josephson parametric amplifiers have become a critical tool in superconducting device physics due to their high gain and quantum-limited noise. Traveling wave parametric amplifiers…
Digital quantum simulation of fermionic models with a superconducting circuit
R. Barends, L. Lamata, J. Kelly +21
Simulating quantum physics with a device which itself is quantum mechanical, a notion Richard Feynman originated, would be an unparallelled computational resource. However, the uni…
