2. 1. Read-out of superconducting qubits - a quantum measurement process

   Author : Lars Tornberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; superconducting qubits; single Cooper Pair box; quantum measurements; quantum electrical circuits; quatum computing;

   Abstract : In this work we consider measurements on quantum systems emphasizingon read-out of superconducting qubits. The qubit is always coupled to anenvironment, containing a macroscopic number of degrees of freedom. Thisperturbs the qubit and destroys the phase coherence of the quantum state. READ MORE

4. 2. Superconducting qubits - measurement, entanglement, and noise

   Author : Lars Tornberg; Chalmers tekniska högskola; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; Quantum Electric Circuits; Open Quantum Systems; Quantum Optics; Quantum Computing; Superconducting Qubits; Quantum Measurement;

   Abstract : In the early 1980’s, it was suggested that a computer obeying the laws of quantum mechanics would be able to solve problems beyond the capabilities of a classical computer. The novel ways in which such a quantum computer works relies on the quantum properties of the quantum bits (qubits) used to store the information. READ MORE
