Superconducting Qubits: A Short Review

  title={Superconducting Qubits: A Short Review},
  author={Michel H. Devoret and Andreas Wallraff and John M. Martinis},
  journal={arXiv: Mesoscale and Nanoscale Physics},
Superconducting qubits are solid state electrical circuits fabricated using techniques borrowed from conventional integrated circuits. They are based on the Josephson tunnel junction, the only non-dissipative, strongly non-linear circuit element available at low temperature. In contrast to microscopic entities such as spins or atoms, they tend to be well coupled to other circuits, which make them appealling from the point of view of readout and gate implementation. Very recently, new designs of…

Characterization of a fabrication process for the integration of superconducting qubits and rapid-single-flux-quantum circuits
In order to integrate superconducting qubits with rapid-single-flux-quantum (RSFQ) control circuitry, it is necessary to develop a fabrication process that simultaneously fulfils the requirements of
Single artificial-atom lasing
This work demonstrates a lasing effect with a single artificial atom—a Josephson-junction charge qubit—embedded in a superconducting resonator.


NMR-like control of a quantum bit superconducting circuit.
Experiments are reported on in which the state of a qubit circuit, the quantronium, is efficiently manipulated using methods inspired from nuclear magnetic resonance (NMR): multipulse sequences are used to perform arbitrary operations, to improve their accuracy, and to fight decoherence.
Nondestructive readout for a superconducting flux qubit.
The intrinsic flux detection efficiency and backaction are suitable for a fast and nondestructive determination of the quantum state of the qubit, as needed for readout of multiple qubits in a quantum computer.
Qubits as Spectrometers of Quantum Noise
Electrical engineers and physicists are naturally very interested in the noise of circuits, amplifiers and detectors. This noise has many origins, some of which are completely unavoidable. For
Spectroscopy on two coupled superconducting flux qubits.
Spectroscopy measurements on two coupled flux qubits show the coupling strength agrees with calculations of the mutual inductance and resonances due to transitions from the ground state to the first two excited states are observed.

Anyon superconductivity?
It is argued that for large n perturbation theory is reliable and exhibits superfluidity (or superconductivity after coupling to electromagnetism) and the order parameter is described in terms of “spontaneous breaking of commutativity of translations” as opposed to the usual pairing order parameters.
