Nature 500, 319-322 (2013)

Demonstrations of primitive information processing elements with quantum bits (qubits) have been
implemented in many systems, but the requirements for precise quantum control, along with fast classical
feed-forward (conditioning future operations on measurement results) has proved challenging.

Atomic clocks have been instrumental in science and technology, leading to innovations such as global
positioning, advanced communications, and tests of fundamental constant variation. Timekeeping precision
at 1 part in 1018 enables new timing applications in relativistic geodesy, enhanced Earth- and space-based
navigation and telescopy, and new tests of physics beyond the standard model.

Enhanced sensitivity of the LIGO gravitational wave detector by using squeezed states of light

J. Aasi, et al.
Nature Photonics 7, 613–619 (2013)

A global network of observatories is seeking to directly detect gravitational waves using precision laser
interferometry. Photon shot noise, due to the quantum nature of light, imposes a fundamental limit on the
attometre-level sensitivity of the kilometre-scale Michelson interferometers deployed for this task.

Microscopic observation of magnon bound states and their dynamics

T. Fukuhara, P. Schauß, M. Endres, S. Hild, M. Cheneau, I. Bloch and C. Gross
Nature 502, 76-79 (2013)

More than eighty years ago Hans Bethe predicted that elementary spin waves, known as magnons, in onedimensional
quantum magnets can form bound states - i.e. that two magnons can pair up and propogate
together. Identifying signatures of magnon bound states has so far remained the subject of intense theoretical
research, and their detection has proved challenging for experiments.
