1. 1. Sample and hold measurement for binary detection of a quantum state

   Författare :Jochen Walter; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Other physics; Övrig fysik;

   Sammanfattning : Measuring the dynamics of a quantum bit (qubit) relies on the accurate detection of the quantum state of the system. A widely used method to measure the state of a solid state Josephson junction qubit is to measure the switching current of a Josephson device. LÄS MER

3. 2. Pulse and hold switching current readout of superconducting quantum circuits

   Författare :Jochen Walter; David Haviland; Hans Mooij; KTH; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Josephson junction; readout; qubit; detector; frequency dependent damping; quantronium; phase-space; correlation analysis; Physics; Fysik;

   Sammanfattning : Josephson junction qubits are promising candidates for a scalable quantum processor. Such qubits are commonly manipulated by means of sequences of rf-pulses and different methods are used to determine their quantum state. LÄS MER
