The performance of superfast quantum computers can be significantly increased by the use of quantum memories based on the so-called microwave cavity resonators. This was confirmed by research by scientists from the Department of Optics, Faculty of Science, Palacký University in Olomouc and experts from the Yale Quantum Institute in the United States of America.
Resonators significantly extend the lifetime of photons, which play the role of quantum bits, on which the mechanism of functioning of quantum computers is built. Microwave cavity resonators represent an ideal system for quantum memories, as they extend the lifetime of photons up to tens of milliseconds. This is approximately a hundred times longer than quantum bits based on non-linear circuits. In addition, there are methods by which the “lifetime” of cavity resonators can be stretched to a few seconds.
