“Los Alamos National Laboratory have developed a new Quantum #computing algorithm that offers a clearer understanding of the #quantum-to-classical transition” reads a tweet from the Los Alamos Lab (@LosAlamosNatLab).
Reportedly, the algorithm will offer a conceptual figuring that will help model systems on the “cusp” of quantum and the traditional system world such as the sequencing of molecular proteins or biological proteins and will provide answers to some of the most complicated questions that applies to large-scale objects.
To answer the arising queries regarding the transition being talked about, Patrick Coles of the Physics of Condensed Matter and Complex Systems group at Los Alamos National Laboratory says that,
“The quantum-to-classical transition occurs when you add more and more particles to a quantum system…such that the weird quantum effects go away and the system starts to behave more classically. For these systems, it’s essentially impossible to use a classical computer to study the quantum-to-classical transition. We could study this with our algorithm and a quantum computer consisting of several hundred qubits, which we anticipate will be available in the next few years based on the current progress in the field.”, mentioned in a post by Phys.OrgPhys.Org
The answer to the quantum-to classical transition is difficult on most of the grounds since just the addition of a single atom makes the situation grow exponentially. Stating the example of Proteins, the post explains that they consist of long strings of molecules in sequences which according to their flooding may serve as an important biological component or become the source of diseases. Proteins are larger molecules but they are not that large for quantum-to-classical transition along with Algorithm – which can absolutely handle it. In this scenario, it becomes important to try to understand and predict how proteins fold.
For determining the aspects of the quantum-to-classical transition on a quantum computer, it is necessary to categorize how close the quantum system behaves to the classical system. In the words of the research,
“Quantum objects have characteristics of both particles and waves. In some cases, they interact like tiny billiard balls, in others, they interfere with each other in much the same way that waves on the ocean combine to make larger waves or cancel each other out. The wave-like interference is a quantum effect”
The quantum system is an accumulation of intuitive classical probabilities which has no complexities as quantum mechanics when there is a lack of any evident interference. With the results, the team searched for classicality in quantum systems to understand the quantum system with the classical approach that is common in our regular lives.
