Achievability of two qubit gates using linear optical elements and post-selection
Josh Cadney
We study the class of two qubit gates which can be achieved using only linear optical elements (beam splitters and phase shifters) and post-selection. We are able to exactly charac…
Inequalities for the Ranks of Quantum States
Josh Cadney, Marcus Huber, Noah Linden +1
We investigate relations between the ranks of marginals of multipartite quantum states. These are the Schmidt ranks across all possible bipartitions and constitute a natural quanti…
Measurement entropy in Generalized Non-Signalling Theory cannot detect bipartite non-locality
Josh Cadney, Noah Linden
We consider entropy in Generalized Non-Signalling Theory (also known as box world) where the most common definition of entropy is the measurement entropy. In this setting, we compl…
Infinitely many constrained inequalities for the von Neumann entropy
Josh Cadney, Noah Linden, Andreas Winter
We exhibit infinitely many new, constrained inequalities for the von Neumann entropy, and show that they are independent of each other and the known inequalities obeyed by the von…
