Spin echo silencing using a current-biased frequency-tunable resonator
V. Ranjan, Y. Wen, A. K. V. Keyser +5
The ability to control microwave emission from a spin ensemble is a requirement of several quantum memory protocols. Here, we demonstrate such ability by using a resonator whose fr…
Pulsed electron spin resonance spectroscopy in the Purcell regime
Vishal Ranjan, Sebastian Probst, Bartolo Albanese +8
When spin relaxation is governed by spontaneous emission of a photon into the resonator used for signal detection (the Purcell effect), the relaxation time depends on the spi…
Shot noise of a quantum dot measured with GHz stub impedance matching
T. Hasler, M. Jung, V. Ranjan +3
The demand for a fast high-frequency read-out of high impedance devices, such as quantum dots, necessitates impedance matching. Here we use a resonant impedance matching circuit (a…
Clean carbon nanotubes coupled to superconducting impedance-matching circuits
V. Ranjan, G. Puebla-Hellmann, M. Jung +6
Coupling carbon nanotube devices to microwave circuits offers a significant increase in bandwidth and signal-to-noise ratio. These facilitate fast non-invasive readouts important f…
