Top Updates on Quantum Computing in 2019

Quantum Computing

Rigetti, an emerging company engaged in quantum computing research, expects to release a 128-bit computing system in 2019. This implementation will be a major advancement in the quantum field, and it will mark our distance from Quantum Advantage and quantum hegemony. Quantum Supremacy is one step closer to these two goals.

Quantum Computing

Quantum advantage means that quantum computers can perform computations hundreds or even thousands of times faster than classic computers, which means that once a quantum computer is powerful enough to perform calculations that the classic supercomputer cannot perform at all, the goal of quantum hegemony Realization will become a matter of course. Building a computing system with higher qubits is the basis for quantum computing to achieve the ultimate goal of quantum superiority and quantum hegemony. Currently, the field is rapidly developing.

In 1998, researchers at IBM, Oxford, Berkeley, Stanford, and the Massachusetts Institute of Technology produced a 2-bit computing system. In 2018, Google confirmed that it was able to build a 72-bit computing system. And Rigetti announced that it will further develop quantum computing systems: a 128-bit quantum system will be released within a year. Although quantum computing is still not a household term for the outside world, quantum computing is actually a fairly new technology introduced in 1982. The fundamental difference between the computer systems we use today and the quantum computing systems is the way the backend processes information.

Classical computers rely on binary systems, which means that computers can only use 0 and 1 to process information. The bit is the smallest unit of data in the computer, and all running application data and emerging images are translated into bits for the purpose of enabling the computer to recognize and process.

A qubit is based on information that can only exist in one state or another, and can only process one bit at a time, and handles complex calculations by making it two-dimensional. Qubits can process information that exists in multiple states at the same time. This is called superposition, which means that qubits can maintain 0, 1 or any combination of 0 and 1, so that the quantum system has a ratio. The potential for faster and more efficient binary systems.
