Dephasing in a crystal-phase defined double quantum dot charge qubit strongly coupled to a high-impedance resonator
Antti Ranni, Subhomoy Haldar, Harald Havir +8
Dephasing of a charge qubit is usually credited to charge noise in the environment. Here we show that charge noise may not be the limiting factor for the qubit coherence. To this e…
Microwave power harvesting using resonator-coupled double quantum dot photodiode
Subhomoy Haldar, Drilon Zenelaj, Patrick P. Potts +5
We demonstrate a microwave power-to-electrical energy conversion in a resonator-coupled double quantum dot. The system, operated as a photodiode, converts individual microwave phot…
High Impedance Josephson Junction Resonators in the Transmission Line Geometry
Antti Ranni, Harald Havir, Subhomoy Haldar +1
In this article we present an experimental study of microwave resonators made out of Josephson junctions. The junctions are embedded in a transmission line geometry so that they in…
Quantum Dot Source-Drain Transport Response at Microwave Frequencies
Harald Havir, Subhomoy Haldar, Waqar Khan +5
Quantum dots are frequently used as charge sensitive devices in low temperature experiments to probe electric charge in mesoscopic conductors where the current running through the…
