Beyond "0" and "1", the new quantum computer unlocks more computing power by using the seven ion states in the calcium atom

2022-07-22

Thomas Muntz team of the Department of experimental physics of Innsbruck University in Austria successfully developed a quantum computer, which can use the so-called "quantum numbers" to perform arbitrary calculations, thus releasing more computing power with fewer quantum particles. The research results were published in the latest issue of Nature Physics. Computers use 0 and 1, that is, binary information for operations. On this basis, today's quantum computers are also designed with binary information processing in mind. "However, the building blocks of quantum computers are not just 0 and 1", explained Martin linpaul, an experimental physicist at the University of Innsbruck. "Limiting them to binary systems will prevent these devices from realizing their true potential." Although storing information in 0 and 1 is not the most efficient way to calculate, it is the simplest way. Simplicity usually means reliability, robustness and error resistance, so binary information has become an unchallenged standard for classical computers. In the quantum world, the situation is very different. For example, in the Innsbruck quantum computer, information is stored in a single captured calcium atom. Each of these atoms naturally has eight different states, and usually only two of them are used to store information. But in fact, almost all existing quantum computers can access more quantum states. Quantum computers developed by physicists at the University of Innsbruck can use up to seven states in calcium atoms to make full use of their potential. Contrary to classic cases, using more States does not reduce the reliability of computers. Researchers said that there are naturally not only two states in quantum systems. New research has proved that multiple states can also be well controlled. On the other hand, many tasks requiring quantum computers, such as problems in physics, chemistry or material science, are naturally expressed in quantum digital language. Rewriting language for qubits is too complex for today's quantum computers. "It is very natural not only for quantum computers, but also for their applications to surpass 0 and 1, which enables us to unleash the real potential of quantum systems," linpaul explained Editor in chief circle physicists' expectation of quantum computers is to achieve far faster computing speed than existing computers through some incredible properties of microscopic matter. The law of quantum computing plays a key role in it. It would be a revolutionary breakthrough if the potential of microscopic particles, such as multistate, could be truly used by quantum computers, because it not only embodies the conceptual superiority, but also enables all quantum computing capabilities to leap and become handy.
