Efficient one- and two-qubit pulsed gates for an oscillator stabilized Josephson qubit
Frederico Brito, David P. DiVincenzo, Roger H. Koch +1
We present theoretical schemes for performing high-fidelity one- and two-qubit pulsed gates for a superconducting flux qubit. The "IBM qubit" consists of three Josephson junctions,…
Polynomial-time algorithm for simulation of weakly interacting quantum spin systems
Sergey Bravyi, David DiVincenzo, Daniel Loss
We describe an algorithm that computes the ground state energy and correlation functions for 2-local Hamiltonians in which interactions between qubits are weak compared to single-q…
Model for l/f Flux Noise in SQUIDs and Qubits
Roger H. Koch, David P. DiVincenzo, John Clarke
We propose a model for 1/f flux noise in superconducting devices (f is frequency). The noise is generated by the magnetic moments of electrons in defect states which they occupy fo…
