Solitary waves that maintain their shape as they propagate, known as solitons, occur in many physical
systems, from water waves, to light pulses to quantum mechanical matter waves in superfluids and
superconductors. Solitons are highly nonlinear and localized, properties which make them very sensitive
probes of the medium in which they propagate.

Classical command of quantum systems

Quantum computation and cryptography both involve scenarios in which a user interacts with a quantum
system which is either imperfectly characterised or even "untrusted" (i.e. possibly supplied by an adversary
or eavesdropper). It is thus both fundamental and practical to devise ways to reveal whether the system
behaves as desired. For example, Bell inequalities allow one to certify that a system is behaving quantum
mechanically and not classically.

Universal quantum computation with little entanglement

M. Van den Nest
Phyical Review Letters 110, 060504 (2013)

It is strongly expected that quantum computers will offer an exponential computation advantage over their
classical counterparts. It is therefore a fundamental problem to understand what aspect or aspects of quantum
mechanics are responsible for this improvement, which remains largely unsolved. A natural candidate is the
entanglement present in quantum mechanics as the source of the computation power, however there is no
decisive evidence that the answer actually lies there.
