Coplanar waveguides play an important role in the field of solid state quantum computing, e.g. for the coupling of microwave photons to a superconducting qubit.In particular the research field of circuit quantum electrodynamics was initiated with coplanar waveguide resonators as crucial elements that allow for high field strength and thus strong coupling to a superconducting qubit by confining ...
The resonant devices in the circuit QED architecture can be implemented using a superconducting LC resonator, a high purity cavity, [5] or a superconducting coplanar waveguide microwave resonators, [6] [7] which are two-dimensional microwave analogues of the Fabry–Pérot interferometer, in which the capacitance and inductances are distributed.
An RF power amplifier incorporating planar circuit structures. The amplifier on the left feeds its output into a set of planar transmission line filters in the centre. The third circuit block on the right is a circulator to protect the amplifier from accidental reflections of the power back from the antenna
RF engineers commonly use short pieces of transmission line, usually in the form of printed planar transmission lines, arranged in certain patterns to build circuits such as filters. These circuits, known as distributed-element circuits , are an alternative to traditional circuits using discrete capacitors and inductors .
In radio-frequency engineering and communications engineering, a waveguide is a hollow metal pipe used to carry radio waves. [1] This type of waveguide is used as a transmission line mostly at microwave frequencies, for such purposes as connecting microwave transmitters and receivers to their antennas, in equipment such as microwave ovens, radar sets, satellite communications, and microwave ...
Via hole equivalent circuit. The design of the fence needs to consider the size and spacing of the vias. Ideally, vias should act as short circuits, but they are not ideal and a via equivalent circuit can be modelled as a shunt inductance. Sometimes, a more complex model is required such as the equivalent circuit shown in figure 4.
Planar transmission lines, such as microstrip, coplanar waveguide and stripline, can also make good resonators and filters. The processes used to manufacture microstrip circuits is very similar to the processes used to manufacture printed circuit boards and these filters have the advantage of largely being planar.
Transmons have been explored for use as d-dimensional qudits via the additional energy levels that naturally occur above the qubit subspace (the lowest two states). For example, the lowest three levels can be used to make a transmon qutrit; in the early 2020s, researchers have reported realizations of single-qutrit quantum gates on transmons [10] [11] as well as two-qutrit entangling gates.
