Quantum Computation With Mesoscopic Superconducting Devices
Abstract
The goal of this research was to explore the use of superconducting circuits as components for quantum computing Quantum computers are devices that store information on quantum variables and process that information by making those variables interact in a way that preserves quantum coherence. Typically, these variables consist of two quantum states, and the quantum device is called a quantum bit or qubit Superconducting quantum circuits have been proposed as qubits, in which circulating currents of opposite polarity characterize the two quantum states. Recent experiments show that these two macroscopic quantum states can be put into a superposition. In particular, microwave spectroscopy experiments indicate symmetric and anti-symmetric quantum superpositions of macroscopic states.
