Researchers from Arizona State University and Zhejiang University in China, along with two theorists from the United Kingdom, have been able to demonstrate for the first time that large numbers of quantum bits, or qubits, can be tuning to interact with each other.
This can now be done in atom systems.
In a paper to be published in Nature Physics, a group of people demonstrate the emergence of quantum many. It is possible to achieve high processing speed and low power consumption with the use of exotic quantum states.
QMBS states have the ability of multipartite entanglement, which makes them appealing to applications such as quantum sensor and metrology.
Classical computing uses transistors that can only represent the number one or the number two at a time. qubits can represent both 0 and 1 at the same time.
It is necessary to assemble a large number of fundamental information-processing units. Maintaining a high degree of coherence among the qubits is important for quantum computing.
It is possible for the qubits and environmental noise to ruin the coherence in a very short time. Many interacting qubits make up a large body system.
The goal of the research is to understand how to delay thermalization to maintain coherence.
The process of thermalization is a result of a system of many interacting particles. The process of quantum thermalization is caused by the scrambling among many qubits.
The findings of quantum computing will have applications in a number of areas.
