Testing quantum circuits and detecting insecure encryption
Bill Rosgen
We show that computational problem of testing the behaviour of quantum circuits is hard for the class of problems known as QMA that can be verified efficiently with a quantum compu…
Device-independent certification of entangled measurements
Rafael Rabelo, Melvyn Ho, Daniel Cavalcanti +2
We present a device-independent protocol to test if a given black-box measurement device is entangled, that is, has entangled eigenstates. Our scheme involves three parties and is…
All non-classical correlations can be activated into distillable entanglement
Marco Piani, Sevag Gharibian, Gerardo Adesso +3
We devise a protocol in which general non-classical multipartite correlations produce a physically relevant effect, leading to the creation of bipartite entanglement. In particular…
Weaker entanglement guarantees stronger entanglement
Masahito Hayashi, Lin Chen
The monogamy of entanglement is one of the basic quantum mechanical features, which says that when two partners Alice and Bob are more entangled then either of them has to be less…
Test-State Approach to the Quantum Search Problem
Arun Sehrawat, Le Huy Nguyen, Berthold-Georg Englert
The search for "a quantum needle in a quantum haystack" is a metaphor for the problem of finding out which one of a permissible set of unitary mappings---the oracles---is implement…
Changepoint Problem in Quantumn Setting
Daiki Akimoto, Masahito Hayashi
In the changepoint problem, we determine when the distribution observed has changed to another one. We expand this problem to the quantum case where copies of an unknown pure state…
