A bright on-demand source of anti-bunched microwave photons based on inelastic Cooper pair tunneling
Alexander Grimm, Florian Blanchet, Romain Albert +8
The ability to generate single photons is not only an ubiquitous tool for scientific exploration with applications ranging from spectroscopy and metrology to quantum computing, but…
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…
Quantum Process Tomography of a Universal Entangling Gate Implemented with Josephson Phase Qubits
Radoslaw C. Bialczak, Markus Ansmann, Max Hofheinz +9
Quantum logic gates must perform properly when operating on their standard input basis states, as well as when operating on complex superpositions of these states. Experiments usin…
Uncollapsing of a quantum state in a superconducting phase qubit
Nadav Katz, Matthew Neeley, M. Ansmann +8
We demonstrate in a superconducting qubit the conditional recovery ("uncollapsing") of a quantum state after a partial-collapse measurement. A weak measurement extracts information…
High-fidelity gates in a Josephson qubit
Erik Lucero, M. Hofheinz, M. Ansmann +7
We demonstrate new experimental procedures for measuring small errors in a superconducting quantum bit (qubit). By carefully separating out gate and measurement errors, we construc…
