Quantum Computers Promise Huge Advantages over Conventional Devices

Quantum Computers

The field of quantum mechanics has dramatically evolved in the past few years, especially with respect to computing processes. And now, scientists have thoroughly demonstrated how quantum computers offer mammoth advantaged over conventional computers.

More Insights into Recent Quantum Computing Studies

Robert König, a professor for the theory of complex quantum systems at the Technical university of Munich (TUM), leads a recent study in this field. This research is being carried out in collaboration with David Gosset from the Institute for Quantum Computing at the University of Waterloo and Sergey Bravyi from IBM. They have essentially developed a quantum circuit, which can certainly be able to solve any problems faced by computing processes in future as compared to any equivalent classical circuit.

This cornerstone research has been demonstrated successfully by König and his colleagues. The quantum circuit developed by them can solve specific algebraic problems having a very complex nature for now. The circuit has a simple structure and a constant depth – it can perform a fixed number of operations on each qubit. A major part of this study involves working in the domain of non-locality of quantum physics.

Before this study, physical evidence of the use of quantum computers existed only theoretically, with only the evidence being pointed in the same direction. According to Robert König, the new results primarily exist as a key contribution to complexity theory. He further states that their results do not need to rely on unproven complexity-theoretic conjectures. After this achievement, the work will provide new milestones on the road to quantum computers. Because of its simple structure, the new quantum circuit certainly can be considered as a near-term experimental realization of quantum algorithms.

TUM along with Ludwig-Maximilians-Universität München (LMU) was awarded the contract for the Cluster of Excellence Munich Center for Quantum Science and Technology (MCQST) in September for the research on quantum computing.
