The Degree of Quantum Contextuality in terms of Concurrence for the KCBS Scenario
Firat Diker, Zafer Gedik
Quantum contextuality is the key concept which explains the fact that the result of a measurement is not independent of the context in which it is found. It is observed to be an in…
Weak Measurement of Berry's Phase
Z. Gedik
Quantum measurements can be generalized to include complex quantities. It is possible to relate the quantum weak values of projection operators to the third order Bargmann invarian…
Optimal upper bound of entropic uncertainty relation for mutually unbiased bases
Bilal Canturk, Zafer Gedik
We have obtained the optimal upper bound of entropic uncertainty relation for Mutually Unbiased Bases (MUBs). We have used the methods of variational calculus for the states th…
Optimization and experimental realization of the quantum permutation algorithm
İ. Yalçınkaya, Z. Gedik
The quantum permutation algorithm provides computational speed-up over classical algorithms in determining the parity of a given cyclic permutation. For its -qubit implementatio…
Magic informationally complete POVMs with permutations
Michel Planat, Zafer Gedik
Eigenstates of permutation gates are either stabilizer states (for gates in the Pauli group) or magic states, thus allowing universal quantum computation [M. Planat and Rukhsan-Ul-…
Two-dimensional quantum walk under artificial magnetic field
İ. Yalçınkaya, Z. Gedik
We introduce the Peierls substitution to a two-dimensional discrete-time quantum walk on a square lattice to examine the spreading dynamics and the coin-position entanglement in th…
