Quantum computers have the potential to be revolutionary tools for their ability to perform calculations that would take classical computers many years to resolve.
But to make an effective quantum computer, you need a reliable quantum bit, or qubit, that can exist in a simultaneous 0 or 1 state for a sufficiently long period, known as its coherence time.
A team of international scientists led by the University of Ottawa have gone back to the kitchen cupboard to create a recipe that combines organic material and light to create quantum states.
The quantum internet would be a lot easier to build if we could use existing telecommunications technologies and infrastructure. Over the past few years, researchers have discovered defects in silicon—a ubiquitous semiconductor material—that could be used to send and store quantum information over widely used telecommunications wavelengths.
Finnish company IQM Quantum Computers has won French government funding to build what is claimed to be the first industrial-scale quantum processor production facility in Europe. The factory was announced at last month’s Choose France summit, where foreign companies pledged to invest €15 billion in the country and the €150 million project will be part financed under the France 2030 investment plan.
In a significant milestone for quantum communication technology, an experiment has demonstrated how networks can be leveraged to combat disruptive 'noise' in quantum communications.
Quantum computers promise to tackle some of the most challenging problems facing humanity today. While much attention has been directed towards the computation of quantum information, the transduction of information within quantum networks is equally crucial in materializing the potential of this new technology.
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 a certain class of such problems can actually be solved better and much faster with quantum computers than with conventional methods.
The team's work is published in the journal Science Advances.
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 at TU Darmstadt have recently taken a decisive step toward achieving this goal.
