Spin Model for Quantum Annealing with Kerr Parametric Oscillators
Leo Stenzel, Roeland ter Hoeven, Ryoji Miyazaki +3
Coherent states offer a promising path for near-term quantum computing due to their inherent protection against bit-flip noise. However, their large photon numbers can be challengi…
Expanding the Neutral Atom Gate Set: Native iSWAP and Exchange Gates from Dipolar Rydberg Interactions
Pedro Ildefonso, Andrew Byun, Aleksei Konovalov +3
We present a native realization of iSWAP and parameterized \textit{exchange} gates for neutral-atom quantum processing units. Our approach leverages strong dipole-dipole interactio…
Fermion lattices can be simulated by same-size qubit lattices with interaction overhead
Gregor Aigner, Berend Klaver, Martin Lanthaler +1
Local interactions among electrons underlie many complex properties of correlated materials. While the Jordan-Wigner transformation can preserve this locality along one spatial dim…
Demonstrating Record Fidelity for the Quantum Fourier Transform
Philipp Aumann, Michael Fellner, David Alber +6
We demonstrate the Parity Architecture on quantum hardware, using the quantum Fourier transform (QFT) as a benchmark. As a result, a record performance in both fidelity and qubit c…
YZ-plane measurement-based quantum computation: Universality and Parity Architecture implementation
Jaroslav Kysela, Katharina Ludwig, Nitica Sakharwade +2
We define the class of register-logic graphs and prove that any uniformly deterministic measurement-based quantum computation (MBQC) where the inputs coincide with the outputs must…
Replacement-Type Quantum Gates
Florian Ginzel, Javad Kazemi, Valentin Torggler +1
We introduce the paradigm of replacement-type quantum gates. This type of gate introduces input qubits, candidate qubits, and output qubits. The candidate qubits are prepared such,…
