The American National Institute of Standards and Technology (NIST) has developed a toggle switch that can track cubes, which are the basis for quantum calculations. This switch can change its condition depending on whether it is necessary to carry out calculations or measure the results.
The device consists of two superconducting quantum bits (cubes) and a toggle switch that connects them to a “resonator for reading.” The design is meant to reduce noise, which is a factor that often prevents scientists from performing computing and clearly demonstrating the results of computer technology. Scientists believe that a new form of calculations will be able to perform tasks more effectively than ordinary computers, leading to breakthroughs in various fields of research, such as energy and healthcare.
The toggle switch can be translated into different states to adjust the connection force between the cubes and the resonator for reading. When the toggle switch is turned off, all three elements are isolated from each other. When the toggle switch is turned on, it connects two cubes and allows them to interact and perform calculations. After the calculations are completed, the switch can connect any of the cubes to the resonator for reading and obtaining results.
The scientists who developed the device hope that this architecture will help to protect cubes and promise to improve the ability to make high-precision measurements required for building quantum processors from cubes. Further research could give an idea of how to tie many of these devices together, potentially offering a way to create a powerful quantum computer with a sufficient number of cubes to solve problems that are currently irresistible.
A diagram of the central working area of the device shows three large rectangles in the lower part, with two cubes on the right and left and a resonator in the center. At the top, the passage of microwaves through the antenna induces the magnetic field in the Squid loop, which activates the toggle switch. The frequency and value of the microwaves determine the position of the switch and the force of the connection between the cubes and the resonator.
Previously, Intel introduced the new Tunnel Falls quantum processor built on a silicon basis, which will be available to several US universities and researchers to personally work with this hardware. Intel said that Tunnel Falls is the most advanced Intel chip today with silicon spin cubes created on the basis of many years of experience in the development and production of transistors.
