Wirebond crosstalk and cavity modes in large chip mounts for superconducting qubits
J. Wenner, M. Neeley, Radoslaw C. Bialczak +8
We analyze the performance of a microwave chip mount that uses wirebonds to connect the chip and mount grounds. A simple impedance ladder model predicts that transmission crosstalk…
Deterministic entanglement of photons in two superconducting microwave resonators
H. Wang, Matteo Mariantoni, Radoslaw C. Bialczak +12
Quantum entanglement, one of the defining features of quantum mechanics, has been demonstrated in a variety of nonlinear spin-like systems. Quantum entanglement in linear systems h…
Photon shell game in three-resonator circuit quantum electrodynamics
Matteo Mariantoni, H. Wang, Radoslaw C. Bialczak +12
The generation and control of quantum states of light constitute fundamental tasks in cavity quantum electrodynamics (QED). The superconducting realization of cavity QED, circuit Q…
Demonstration of a Tuneable Coupler for Superconducting Qubits Using Coherent, Time Domain, Two-Qubit Operations
R. C. Bialczak, M. Ansmann, M. Hofheinz +11
A major challenge in the field of quantum computing is the construction of scalable qubit coupling architectures. Here, we demonstrate a novel tuneable coupling circuit that allows…
Reduced phase error through optimized control of a superconducting qubit
Erik Lucero, Julian Kelly, Radoslaw C. Bialczak +11
Minimizing phase and other errors in experimental quantum gates allows higher fidelity quantum processing. To quantify and correct for phase errors in particular, we have developed…
Quantum process tomography of two-qubit controlled-Z and controlled-NOT gates using superconducting phase qubits
T. Yamamoto, M. Neeley, E. Lucero +12
We experimentally demonstrate quantum process tomography of controlled-Z and controlled-NOT gates using capacitively-coupled superconducting phase qubits. These gates are realized…
