A Fully Quantum Asymptotic Equipartition Property
TLDR
A fully quantum generalization of the classical asymptotic equipartition property is shown, where both the output of the experiment and side information are quantum.

No extension of quantum theory can have improved predictive power
TLDR
This work says that no extension of quantum theory can give more information about the outcomes of future measurements than quantum theory itself, under the assumption that measurements can be chosen freely.

The uncertainty principle in the presence of quantum memory
The Heisenberg uncertainty principle bounds the uncertainties about the outcomes of two incompatible measurements on a quantum particle. This bound, however, changes if a memory device is involved…

Duality Between Smooth Min- and Max-Entropies
TLDR
In this paper, a recently discovered duality relation between (nonsmooth) min- and max-entropies is extended to the smooth case and it is shown that the smooth min-entropy of a system A conditioned on a system B equals the negative of the smooth max-Entropy of Acondition on a purifying system C.

Free randomness can be amplified
Bell’s equations enable scientists to test the fundamental implications of quantum physics. A central tenet of this idea is that the choice of measurement is truly random. Researchers now show that…

TLDR
A new protocol for non-relativistic strong coin tossing is introduced, which matches the security of the best protocol known to date while using a conceptually different approach to achieve the task.

Advances in Quantum Cryptography
TLDR
This review begins by reviewing protocols of quantum key distribution based on discrete variable systems, and considers aspects of device independence, satellite challenges, and high rate protocols based on continuous variable systems.

Is a system's wave function in one-to-one correspondence with its elements of reality?
TLDR
It is shown, based only on the assumption that measurement settings can be chosen freely, that a system's wave function is in one-to-one correspondence with its elements of reality, which eliminates the possibility that it can be interpreted subjectively.

Private randomness expansion with untrusted devices
TLDR
This work introduces a protocol for private randomness expansion with untrusted devices which is designed to take as input an initially private random string and produce as output a longerPrivate random string.

Quantum Circuits for Isometries
TLDR
A theoretical lower bound on the number of cnot gates required to decompose an arbitrary isometry from $m$ to $n$ qubits is derived and three explicit gate decompositions are given that achieve this bound up to a factor of about 2 in the leading order.
