The traveling salesman problem is considered a prime example of a combinatorial optimization problem. Now a Berlin team led by theoretical physicist Prof. Dr. Jens Eisert of Freie Universität Berlin and HZB has shown that ...
Researchers at ETH have managed to trap ions using static electric and magnetic fields and to perform quantum operations on them. In the future, such traps could be used to realize quantum computers with far more quantum ...
Two physicists at the University of Konstanz are developing a method that could enable the stable exchange of information in quantum computers. In the leading role: photons that make quantum bits "fly."
Scientists have created a reprogrammable light-based processor, a world-first, that they say could usher in a new era of quantum computing and communication.
In the future, the use of quantum computers could make a significant contribution to promoting greater sustainability in global developments. This was shown in a white paper, which was recently presented at the UN Climate ...
Quantum computing engineers at UNSW Sydney have shown they can encode quantum information—the special data in a quantum computer—in four unique ways within a single atom, inside a silicon chip.
The color centers of diamond are the focus of an increasing number of research studies, due to their potential for developing quantum technologies. Some works have particularly explored the use of negatively-charged group-IV ...
Creating a quantum computer powerful enough to tackle problems we cannot solve with current computers remains a big challenge for quantum physicists. A well-functioning quantum simulator—a specific type of quantum computer—could ...
Making quantum systems more scalable is one of the key requirements for the further development of quantum computers because the advantages they offer become increasingly evident as the systems are scaled up. Researchers ...
A recent study has unveiled a significant advancement toward the on-chip integration of single-photon sources at room temperature. This achievement represents a significant step forward in the field of quantum photonics and ...
