Quantum logic gates are the basic building blocks of a quantum computer, but constructing enough of them to perform a useful computation is difficult.
In the usual approach to quantum computing, quantum gates are applied in a specific order, one gate before another.
But it was realized recently that quantum mechanics permits one to"superimpose quantum gates.""If engineered correctly, this means that a set of quantum gates can act in all possible orders at the same time.
Surprisingly, this effect can be used to reduce the total number of gates required for certain quantum computations.
All orders at once A team led by Philip Walther recently realized that superimposing the order of quantum gates, an idea
which was designed theoretically by the group of Caslav Brukner, could be implemented in the laboratory. In a superposition of quantum gate orders, it is impossible--even in principle--to know
if one operation occurred before another operation, or the other way around. This means that two quantum logic gates A and B can be applied in both orders at the same time.
The results of their experiment confirm that it is impossible to determine which gate acted first
"In fact, we were able to run a quantum algorithm to characterize the gates more efficiently than any previously known algorithm,
From a single measurement on the photon, they probed a specific property of the two quantum gates thereby confirming that the gates were applied in both orders at once.
As more gates are added to the task, the new method becomes even more efficient compared to previous techniques.
The Way Forward This is the first time that a superposition of quantum gates has been implemented in the lab. At the same time
