Engineers Remove Key Roadblock From Real-Life Quantum ComputersMarch 8, 2011 0 Comments
An international team led by engineers from the University of Queensland in Australia have overcome a key hurdle to the real-life applications of quantum computing. In essence, using current technology, engineers have no way of efficiently measuring the behavior of qubits. Like computer bits, "qubits" are the smallest measure of quantum information. According to the article, just an 8-qubit quantum computer would require over a billion measurements. The measuring tasks increase exponentially with the number of qubits.
Dr. Alessandro Fedrizzi, co-author of this study published in Physical Review Letters states:
“Imagine that you're building a car but you can't test-drive it.This is the situation that quantum engineers are facing at the moment.”
The team developed a "compressive sensing algorithm" that for the first time allowed drastic simplification for measuring quantum processes.
Quantum computing is the holy grail of computer technology. We've covered quantum technology developments a few times here on Logic-Cool. The diagram below is a Bloch sphere, a visual representation of a qubit.
