Computed tomography of propagating microwave photons
Qi-Ming Chen, Aarne Keränen, Aashish Sah +1
Propagating photons serve as essential links for distributing quantum information and entanglement across distant nodes. Knowledge of their Wigner functions not only enables their…
Multiplexed readout of Superconductor--Normal-Conductor--Superconductor bolometers
Priyank Singh, András Gunyhó, Heikki Suominen +9
Recently, ultrasensitive calorimeters have been proposed as a resource-efficient solution for multiplexed qubit readout in superconducting large-scale quantum processors. However,…
Correlation measurement of propagating microwave photons at millikelvin
Aarne Keränen, Qi-Ming Chen, András Gunyhó +5
Microwave photons are important carriers of quantum information in many promising platforms for quantum computing. They can be routinely generated, controlled, and teleported in ex…
Decay-protected superconducting qubit with fast control enabled by integrated on-chip filters
Aashish Sah, Suman Kundu, Heikki Suominen +2
Achieving fast gates and long coherence times for superconducting qubits presents challenges, typically requiring either a stronger coupling of the drive line or an excessively str…
