Intrinsic decoherence in superconducting quantum circuits Open
Decoherence and parameter fluctuations are two of the mayor obstacles for solid-state quantum computing. In this work, decoherence in superconducting qubits of the transmon type is investigated. For this purpose, a time-multiplexed measure…
Correlating Decoherence in Transmon Qubits: Low Frequency Noise by Single Fluctuators Open
We report on long-term measurements of a highly coherent, nontunable superconducting transmon qubit, revealing low-frequency burst noise in coherence times and qubit transition frequency. We achieve this through a simultaneous measurement …
Correlating decoherence in transmon qubits: Low frequency noise by single fluctuators Open
We report on long-term measurements of a highly coherent, non-tunable superconducting transmon qubit, revealing low-frequency burst noise in coherence times and qubit transition frequency. We achieve this through a simultaneous measurement…
Concentric transmon qubit featuring fast tunability and an anisotropic magnetic dipole moment Open
We present a planar qubit design based on a superconducting circuit that we call concentric transmon. While employing a straightforward fabrication process using Al evaporation and lift-off lithography, we observe qubit lifetimes and coher…
