Electron cloud design for Rydberg multi-qubit gates
Mohammadsadegh Khazali, Wolfgang Lechner
This article proposes quantum processing in an optical lattice, using Rydberg electron's Fermi scattering from ground-state atoms in spin-dependent lattices as a source of interact…
Polynomial scaling enhancement in ground-state preparation of Ising spin models via counter-diabatic driving
Andreas Hartmann, Glen Bigan Mbeng, Wolfgang Lechner
The preparation of ground states of spin systems is a fundamental operation in quantum computing and serves as the basis of adiabatic quantum computing. This form of quantum comput…
Quantum optimization via four-body Rydberg gates
Clemens Dlaska, Kilian Ender, Glen Bigan Mbeng +3
There is a large ongoing research effort towards obtaining a quantum advantage in the solution of combinatorial optimization problems on near-term quantum devices. A particularly p…
CircuitQ: An open-source toolbox for superconducting circuits
Philipp Aumann, Tim Menke, William D. Oliver +1
We introduce CircuitQ, an open-source toolbox for the analysis of superconducting circuits implemented in Python. It features the automated construction of a symbolic Hamiltonian o…
Parity Quantum Optimization: Benchmarks
Michael Fellner, Kilian Ender, Roeland ter Hoeven +1
We present benchmarks of the parity transformation for the Quantum Approximate Optimization Algorithm (QAOA). We analyse the gate resources required to implement a single QAOA cycl…
Parity Quantum Optimization: Encoding Constraints
Maike Drieb-Schön, Kilian Ender, Younes Javanmard +1
Constraints make hard optimization problems even harder to solve on quantum devices because they are implemented with large energy penalties and additional qubit overhead. The pari…
