On the probability of finding marked connected components using quantum walks
Nikolajs Nahimovs, Raqueline A. M. Santos, Kamil Khadiev
Finding a marked vertex in a graph can be a complicated task when using quantum walks. Recent results show that for two or more adjacent marked vertices search by quantum walk with…
Strong Quantum Solutions in Conflicting Interest Bayesian Games
Ashutosh Rai, Goutam Paul
Quantum entanglement has been recently demonstrated as a useful resource in conflicting interest games of incomplete information between two players, Alice and Bob [Pappa et al., P…
Provably secure key establishment against quantum adversaries
Aleksandrs Belovs, Gilles Brassard, Peter Hoyer +3
At Crypto 2011, some of us had proposed a family of cryptographic protocols for key establishment capable of protecting quantum and classical legitimate parties unconditionally aga…
Quantum algorithm for tree size estimation, with applications to backtracking and 2-player games
Andris Ambainis, Martins Kokainis
We study quantum algorithms on search trees of unknown structure, in a model where the tree can be discovered by local exploration. That is, we are given the root of the tree and a…
Two-Qubit Pure Entanglement as Optimal Social Welfare Resource in Bayesian Game
Manik Banik, Some Sankar Bhattacharya, Nirman Ganguly +4
Entanglement is of paramount importance in quantum information theory. Its supremacy over classical correlations has been demonstrated in numerous information theoretic protocols.…
Level anti-crossing magnetometry with color centers in diamond
Huijie Zheng, Georgios Chatzidrosos, Arne Wickenbrock +7
Recent developments in magnetic field sensing with negatively charged nitrogen-vacancy centers (NV) in diamond employ magnetic-field (MF) dependent features in the photoluminescenc…
