QSHS: An Axion Dark Matter Resonant Search Apparatus
A. Alsulami, I. Bailey, G. Carosi +32
We describe a resonant cavity search apparatus for axion dark matter constructed by the Quantum Sensors for the Hidden Sector (QSHS) collaboration. The apparatus is configured to s…
Emulating two qubits with a four-level transmon qudit for variational quantum algorithms
Shuxiang Cao, Mustafa Bakr, Giulio Campanaro +7
Using quantum systems with more than two levels, or qudits, can scale the computation space of quantum processors more efficiently than using qubits, which may offer an easier phys…
Efficient characterization of qudit logical gates with gate set tomography using an error-free Virtual-Z-gate model
Shuxiang Cao, Deep Lall, Mustafa Bakr +7
Gate-set tomography (GST) characterizes the process matrix of quantum logic gates, along with measurement and state preparation errors in quantum processors. GST typically requires…
Characterisation of spatial charge sensitivity in a multi-mode superconducting qubit
J. Wills, G. Campanaro, S. Cao +3
Understanding and suppressing sources of decoherence is a leading challenge in building practical quantum computers. In superconducting qubits, low frequency charge noise is a well…
High Coherence in a Tileable 3D Integrated Superconducting Circuit Architecture
Peter A. Spring, Shuxiang Cao, Takahiro Tsunoda +11
We report high qubit coherence as well as low crosstalk and single-qubit gate errors in a superconducting circuit architecture that promises to be tileable to 2D lattices of qubits…
Radio-frequency characterization of a supercurrent transistor made from a carbon nanotube
M. Mergenthaler, F. J. Schupp, A. Nersisyan +6
A supercurrent transistor is a superconductor-semiconductor hybrid device in which the Josephson supercurrent is switched on and off using a gate voltage. While such devices have b…
