Novel oracle constructions for quantum random access memory
Ákos Nagy
We present novel ways of designing quantum (random access) memory, also known as quantum dictionary encoders or data-access oracles.
Diagonal operator decomposition on restricted topologies via enumeration of quantum state subsets
Jan Tułowiecki, Łukasz Czerwiński, Konrad Deka, Jan Gwinner, Witold Jarnicki, Adam Szady
We analyze the CX implementation cost of generic diagonal operators, based on the target device topology.
Clifford circuits over non-cyclic abelian groups
Milo Moses, Jacek Horecki, Konrad Deka, Jan Tułowiecki
We present a generalized approach to Clifford group construction for any abelian group.
Fixed-point Grover Adaptive Search for QUBO Problems
Ákos Nagy
We develop and optimize a novel Fixed-point Grover Adaptive Search for QUBO Problems based on our oracle design and previous works of Li et al. to obtain better performance guarantees than Gilliam et al.
Anyons in a highly-entangled toric xy model
Milo Moses, Konrad Deka
We show that in some sense the only obstruction for a toric xy model to have a topological order is a U(1) gauge action.
Creating rotational coherences in molecules aligned along the intermediate moment of inertia axis
Emil Żak
We present a theoretical method for coherently controlling the dynamics of rotating molecules with a tailored-pulse optical centrifuge.

Quantum Computing Algorithms for NISQ Era
Wojciech Burkot
A talk about a family of algorithms specifically constructed for NISQ computers, promising much better results at currently available qubit counts and circuit depths.
A short note on graphs with long Thomason's chains
Marcin Briański, Adam Szady
We present a family of 3-connected cubic planar Hamiltonian graphs with an exponential number of steps required by Thomason's algorithm.
Quantum Boltzmann sampling – noisiness of some existing hardware approaches
Witold Jarnicki
Investigation of the distribution of samples produced by existing methods of sampling from a quantum Boltzmann distribution and comparison to purely theoretical values.
