Quantum computers ‘one step closer’
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.
We’ve figured out how to ensure quantum computers can be trusted
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.
Forging a quantum leap in quantum communication
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…
Why Quantum Computers Will Be an Amazing Tool for Social Innovators — By Darlene Damm | SingularityHub
“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.”
