Special issue on quantum computing with superconducting qubits
Ten years ago the first superconducting qubit was demonstrated experimentally [1]. By now quantum computing with superconducting qubits has become a subject of intensive experimental and theoretical research in dozens of groups around the world. The idea of this Special Issue of the journal is to show the status of experimental research in this area after the first decade of work. Most of the b...
متن کاملFlux-based superconducting qubits for quantum computation
Superconducting quantum circuits have been proposed as qubits for developing quantum computation. The goal is to use superconducting quantum circuits to model the measurement process, understand the sources of decoherence, and to develop scalable algorithms. A particularly promising feature of using superconducting technology is the potential of developing high-speed, on-chip control circuitry ...
متن کاملSuperconducting Qubits Ii : Decoherence
This is an introduction to elementary decoherence theory as it is typically applied to superconducting qubits. Abbreviations: SQUID – superconducting quantum interference device; qubit – quantum bit; TSS – two state system
متن کاملQuantum Logic Gates in Superconducting Qubits
Successful operation of a quantum computer will require unprecedented control of quantum systems. The basic qubit operations, quantum logic gates, are described by the linear Schrodinger equation: the “analog” nature of quantum state evolution makes these logic gates fundamentally sensitive to imperfections in control and loss of energy. In contrast, conventional digital logic can correct error...
متن کاملCoherent operation of coupled superconducting flux qubits
We study the quantum operation of coupled superconducting flux qubits under a microwave irradiation. The flux qubits can be described as magnetic dipole moments in the limit of weak microwave field amplitude consistent with usual experimental situations. With the Hamiltonian for coupled qubits under a microwave field, we show that a strong coupling enables to realize the high performance contro...
