Performance-centric roadmap for building a superconducting quantum computer
R. Barends, F. K. Wilhelm
One of the outstanding challenges in contemporary science and technology is building a quantum computer that is useful in applications. By starting from an estimate of the algorith…
A mathematical justification to apply the secular approximation to the Redfield equation
Niklas J. Jung, Francesco Rosati, Gabriel L. Rath +2
Quantum master equations are widely used to describe the dynamics of open quantum systems. All these different master equations rely on specific approximations that may or may not…
Microscopic model of critical current noise in Josephson-junction qubits: Subgap resonances and Andreev bound states
Rogerio de Sousa, K. Birgitta Whaley, Theresa Hecht +2
We propose a microscopic model of critical current noise in Josephson-junctions based on individual trapping-centers in the tunnel barrier hybridized with electrons in the supercon…
Dynamical tunneling in macroscopic systems
I. Serban, F. K. Wilhelm
We investigate macroscopic dynamical quantum tunneling (MDQT) in the driven Duffing oscillator, charateristic for Josephson junction physics and nanomechanics. Under resonant condi…
Optimal control of a qubit coupled to a non-Markovian environment
P. Rebentrost, I. Serban, T. Schulte-Herbrueggen +1
A central challenge for implementing quantum computing in the solid state is decoupling the qubits from the intrinsic noise of the material. We investigate the implementation of qu…
Engineering decoherence in Josephson persistent-current qubits
Caspar H. van der Wal, F. K. Wilhelm, C. J. P. M. Harmans +1
We discuss the relaxation and dephasing rates that result from the control and the measurement setup itself in experiments on Josephson persistent-current qubits. For control and m…
