With the process of miniaturisation advancing by the day, quantum effects will come to dominate our everyday lives.
At present it is extremely difficult to characterise quantum systems — the number of measurements required increases exponentially with the number of quantum parts. For example, an 8-qubit quantum computer would require over a billion measurements.
“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,” said University of Queensland's Dr Alessandro Fedrizzi, co-author of the study that was recently published in Physical Review Letters.
“We have now found a way to test quantum devices efficiently, which will help transform them from small-scale laboratory experiments to real-world applications.”
