Query: Experimentally attacking quantum money schemes based on quantum
  retrieval games   The concept of quantum money (QM) was proposed by Wiesner in the 1970s. Its
main advantage is that every attempt to copy QM unavoidably leads to imperfect
counterfeits. In the Wiesner's protocol, quantum banknotes need to be delivered
to the issuing bank for verification. Thus, QM requires quantum communication
which range is limited by noise and losses. Recently, Bozzio et al. (2018) have
demonstrated experimentally how to replace challenging quantum verification
with a classical channel and a quantum retrieval game (QRG). This brings QM
significantly closer to practical realisation, but still thorough analysis of
the revised scheme QM is required before it can be considered secure. We
address this problem by presenting a proof-of-concept attack on QRG-based QM
schemes, where we show that even imperfect quantum cloning can, under some
circumstances, provide enough information to break a QRG-based QM scheme.
