摘要： A quantum device includes a non-reciprocal transmission structure, wherein the transmission structure is designed such that for first waves traversing the transmission structure in a forward direction the phases of the first waves are at least partially conserved, and for second waves traversing the transmission structure in a backward direction, the phases of the second waves are at least partially replaced by random ones, such that the phase conservation is more pronounced in the forward direction than in the backward direction.

摘要： A nonreciprocal device includes a waveguide through which waves at a first frequency propagate with a first wavevector and with a second wavevector in a direction opposite to the first wavevector; a frequency-dependent device that operates within a frequency range and modifies the waves through the waveguide in a way that is dependent on the first frequency; and a set of couplers to couple the waveguide and the frequency-dependent device. Coupling rates of the set of couplers are modulated to enable nonreciprocal coupling, with respect to the frequency-dependent device, of the first wavevector compared to the second wavevector.

摘要： A nonreciprocal transmission line apparatus is provided with a cascade connection of unit cells between ports. Each unit cell includes a transmission line part for a microwave signal, and shunt branch circuits equivalently including inductive elements. Each unit cells has spontaneous magnetization or is magnetized by an external magnetic field so as to have gyrotropy by being magnetized in a magnetization direction different from a propagation direction of the transmission line part. In each of the unit cells, the shunt branch circuits includes a first stub conductor formed on one side with respect to a plane composed of the propagation direction and the magnetization direction, and a second stub conductor formed on the other side with respect to the plane, and the stub conductors have different electric length from each other.

摘要： A circulator/isolator assembly is disclosed. The assembly includes a first magnetic substrate having first surface and a second surface and a first ground plane formed on the first surface. A dielectric layer is disposed adjacent first magnetic substrate. The dielectric layer includes a multi-port junction circuit coupled to transmission traces. One of the traces forms an input port and another forms an output port. A first magnet is disposed proximate the multi-port junction circuit of the dielectric layer. The first magnet excites a circular, unidirectional magnetic flux field in the first magnetic substrate that limits electromagnetic wave propagation to a single direction.

摘要： A waveguide matching unit is disclosed. The waveguide matching unit includes a gyrator having first and second waveguides. The first waveguide includes first and second ports that are connected by a first waveguide channel. An RF signal propagating through the first waveguide channel is phase shifted by about 90° when propagating from the first to the second port, and is phase shifted by about 0° when propagating from the second port to the first port. The second waveguide includes third and fourth ports that are connected by a second waveguide channel. An RF signal propagating through the second waveguide channel is phase shifted by about 0° when propagating from the third to the fourth port, and is phase shifted by about 90° when propagating from the fourth port to the third port.
