Coherence-gated quantum devices via real-time weak measurement
Priyank Singh
Single-photon routers in cavity and circuit QED direct photons by the qubit's energy eigenstate -- a projective decision that destroys coherence. We propose a different primitive:…
Quantum dial
Aashish Sah, Suman Kundu, Priyank Singh +3
Accurate control of quantum degrees of freedom is promising for sensing, communication, and computing, but building a useful quantum computer faces a central isolation-and-control…
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…
Low-characteristic-impedance superconducting tadpole resonators in the sub-gigahertz regime
Miika Rasola, Samuel Klaver, Jian Ma +4
We demonstrate a simple and versatile resonator design based on a short strip of a typical coplanar waveguide shorted at one end to the ground and shunted at the other end with a l…
