Flux-tunable heat sink for quantum electric circuits
Matti Partanen, Kuan Yen Tan, Shumpei Masuda +10
Superconducting microwave circuits show great potential for practical quantum technological applications such as quantum information processing. However, fast and on-demand initial…
Overlap junctions for high coherence superconducting qubits
X. Wu, J. L. Long, H. S. Ku +3
Fabrication of sub-micron Josephson junctions is demonstrated using standard processing techniques for high-coherence, superconducting qubits. These junctions are made in two separ…
Qubit gates using hyperbolic secant pulses
H. S. Ku, J. L. Long, X. Wu +5
It has been known since the early days of quantum mechanics that hyperbolic secant pulses possess the unique property that they can perform cyclic evolution on two-level quantum sy…
Electromagnetically induced transparency in circuit QED with nested polariton states
Junling Long, H. S. Ku, Xian Wu +5
Electromagnetically induced transparency (EIT) is a signature of quantum interference in an atomic three-level system. By driving the dressed cavity-qubit states of a two-dimension…
Quantum Gates for Propagating Microwave Photons
Roope Kokkoniemi, Tuomas Ollikainen, Russell E. Lake +6
We report a generic scheme to implement transmission-type quantum gates for propagating microwave photons, based on a sequence of lumped-element components on transmission lines. B…
