Efficient error models for fault-tolerant architectures and the Pauli twirling approximation
Michael R. Geller, Zhongyuan Zhou
The design and optimization of realistic architectures for fault-tolerant quantum computation requires error models that are both reliable and amenable to large-scale classical sim…
Factoring 51 and 85 with 8 qubits
Michael R. Geller, Zhongyuan Zhou
We construct simplified quantum circuits for Shor's order-finding algorithm for composites N given by products of the Fermat primes 3, 5, 17, 257, and 65537. Such composites, inclu…
High-fidelity CZ gate for resonator-based superconducting quantum computers
Joydip Ghosh, Andrei Galiautdinov, Zhongyuan Zhou +3
A possible building block for a scalable quantum computer has recently been demonstrated [M. Mariantoni et al., Science 334, 61 (2011)]. This architecture consists of superconducti…
Entanglement dynamics of a superconducting phase qubit coupled to a two-level system
Guozhu Sun, Zhongyuan Zhou, Bo Mao +3
We report the observation and quantitative characterization of driven and spontaneous oscillations of quantum entanglement, as measured by concurrence, in a bipartite system consis…
Quantum Dynamics of a Microwave Driven Superconducting Phase Qubit Coupled to a Two-Level System
Guozhu Sun, Xueda Wen, Bo Mao +4
We present an analytical and comprehensive description of the quantum dynamics of a microwave resonantly driven superconducting phase qubit coupled to a microscopic two-level syste…
Description of electron transport dynamics in molecular devices: A time-dependent density functional theoretical approach in momentum space makes it simple
Zhongyuan Zhou, Shih-I Chu
We propose a first-principles time-dependent density functional theoretical (TDDFT) approach in momentum (P) space for quantitative study of electron transport in molecular devices…
