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…
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…
Strong coupling between a microwave photon and a singlet-triplet qubit
Jann H. Ungerer, Alessia Pally, Artem Kononov +9
Tremendous progress in few-qubit quantum processing has been achieved lately using superconducting resonators coupled to gate voltage defined quantum dots. While the strong couplin…
Josephson current via spin and orbital states of a tunable double quantum dot
Rousan Debbarma, Markus Aspegren, Florinda Viñas Boström +3
Supercurrent transport is experimentally studied in a Josephson junction hosting a double quantum dot (DQD) with tunable symmetries. The QDs are parallel-coupled to two superconduc…
Wafer-Scale Growth of Sb2Te3 Films via Low-Temperature ALD for Self-Powered Photodetector
Jun Yang, Jianzhu Li, Amin Bahrami +5
In this work, we demonstrate the performance of a silicon-compatible high-performance self-powered photodetector.A wide detection range from visible (405 nm) to near-infrared (1550…
