Quantum computing has taken a step forward with the development of a programmable quantum processor made with silicon.
The team used microwave energy to align two electron particles suspended in silicon, then used them to perform a set of test calculations.
By using silicon, the scientists hope that quantum computers will be more easy to control and manufacture.
Can spot quantum errors IBM research By Mark Kim What good is a fast computer if you can’t trust it? Thanks to half a century of research on getting computers to do their job correctly even in the presence of mechanical errors, our modern machines tend to be pretty reliable. Unfortunately, the laws of sheer complexity of which leaves them prone to errors. Now, we finally have the first demonstration of a quantum program that can detect data corruption.
In quantum communication, the participating parties can detect eavesdropping by resorting to the fundamental principle of quantum mechanics — a measurement affects the measured quantity. Thus, an eavesdropper can be detected by identifying traces his measurements of the communication channel leave behind. The major drawback of quantum communication is the slow speed of data transfer, limited by the speed at which the parties can perform quantum measurements. Researchers at Bar-Ilan University have devised a method that overcomes this, and enables an increase in the rate of data transfer by…
“Eventually, as the kinks are worked out, quantum machines will have a wide impact from scientific research to business. But there’s another area that could benefit from their problem-solving prowess too: Social impact.”
By building the most general framework for the n-particle Hardy’s paradox and Hardy’s inequality, the results of the new paper provide a stronger Hardy’s paradox, and can also detect more quantum entangled states. As the success probability for the three-qubit generalized Hardy’s paradox reaches 0.25, the researchers are very hopeful that it will be observed in future experiments.
