Russian-German team of physicists led by Alexei Ustinov has created the world’s first quantum metamaterial-based solid-state superconducting qubits. His description appeared in the form of
The new device 20 such metaatomov were combined in a quantum system because they are in close proximity to each other and the microwave cavity. This dramatically increased the interaction between the individual qubits is that the experimentally manifested in the form of a small but significant change in the phase of photons absorbed and pereispuskaemyh.
Microwave resonators similar to that used by the authors, are commonly used to create metamaterials — devices that manipulation of the structure in much smaller scale wavelength allows for unusual macroscopic properties. Shown, for example, of such resonators can create
Until now, however, such materials are created from the classical resonator, which have quantum properties. As previously Alexei Ustinov
According to the authors, quantum metamaterials could be used to create a single microwave photon detectors, switches, phase, and many other devices.
