Single-shot readout of multiple donor electron spins with a gate-based sensor
Mark R. Hogg, Prasanna Pakkiam, Samuel K. Gorman +5
Proposals for large-scale semiconductor spin-based quantum computers require high-fidelity single-shot qubit readout to perform error correction and read out qubit registers at the…
Multiplexed readout of kinetic inductance bolometer arrays
Hannu Sipola, Juho Luomahaara, Andrey Timofeev +4
Kinetic inductance bolometer (KIB) technology is a candidate for passive sub-millimeter wave and terahertz imaging systems. Its benefits include scalability into large 2D arrays an…
Thermoelectric bolometers based on ultra-thin heavily doped single-crystal silicon membranes
Andrey V. Timofeev, Aapo Varpula, Andrey Shchepetov +5
We present ultra-thin silicon membrane thermocouple bolometers suitable for fast and sensitive detection of low levels of thermal power and infrared radiation at room temperature.…
Brownian refrigeration by hybrid tunnel junctions
J. T. Peltonen, M. Helle, A. V. Timofeev +3
Voltage fluctuations generated in a hot resistor can cause extraction of heat from a colder normal metal electrode of a hybrid tunnel junction between a normal metal and a supercon…
Electronic Refrigeration at the Quantum Limit
Andrey V. Timofeev, Meri Helle, Matthias Meschke +2
We demonstrate quantum limited electronic refrigeration of a metallic island in a low temperature micro-circuit. We show that matching the impedance of the circuit enables refriger…
Wide-band detection of the third moment of shot noise by a hysteretic Josephson junction
A. V. Timofeev, M. Meschke, J. T. Peltonen +2
We use a hysteretic Josephson junction as an on-chip detector of the third moment of shot noise of a tunnel junction. The detectable bandwidth is determined by the plasma frequency…
Detecting Current Noise with a Josephson Junction in the Macroscopic Quantum Tunneling Regime
J. T. Peltonen, A. V. Timofeev, M. Meschke +1
We discuss the use of a hysteretic Josephson junction to detect current fluctuations with frequencies below the plasma frequency of the junction. These adiabatic fluctuations are p…
Experimental Designs for Binary Data in Switching Measurements on Superconducting Josephson Junctions
Juha Karvanen, Juha J. Vartiainen, Andrey Timofeev +1
We study the optimal design of switching measurements of small Josephson junction circuits which operate in the macroscopic quantum tunnelling regime. Starting from the D-optimalit…
