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…
Zeptojoule Calorimetry
András Gunyhó, Kassius Kohvakka, Qi-Ming Chen +4
The measurement of energy is a fundamental tool used, for example, in exploring the early universe, characterizing particle decay processes, as well as in quantum technology and co…
