Direct Wigner tomography of a superconducting anharmonic oscillator
Yoni Shalibo, Roy Resh, Ofer Fogel +4
The analysis of wave-packet dynamics may be greatly simplified when viewed in phase-space. While harmonic oscillators are often used as a convenient platform to study wave-packets,…
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…
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 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…
