In quantum mechanics, it's impossible to precisely and simultaneously measure the complementary properties (such as the position and momentum) of a quantum state. Now in a new study, physicists have cloned quantum states and demonstrated that, because the clones are entangled, it's possible to precisely and simultaneously measure the complementary properties of the clones. These measurements, in turn, reveal the state of the input quantum system.

The ability to determine the complementary properties of quantum states in this way not only has implications for understanding fundamental quantum physics, but also has potential applications for quantum computing, quantum cryptography, and other technologies.

The physicists, Guillame S. Thekkadath and coauthors at the University of Ottawa, Ontario, have published a paper on determining complementary properties of quantum clones in a recent issue of *Physical Review Letters*.
