A Multilevel Framework for Partitioning Quantum Circuits
Felix Burt, Kuan-Cheng Chen, Kin K. Leung·Mar 24, 2025
Executing quantum algorithms over distributed quantum systems requires quantum circuits to be divided into sub-circuits which communicate via entanglement-based teleportation. Naively mapping circuits to qubits over multiple quantum processing units ...
Simulation of Fermionic circuits using Majorana Propagation
Aaron Miller, Joachim Favre, Zoë Holmes +6 more·Mar 24, 2025
We introduce Majorana Propagation, an algorithmic framework for the classical simulation of Fermionic circuits. Inspired by Pauli Propagation, Majorana Propagation operates by applying successive truncations throughout the Heisenberg evolution of the...
Quantum Memory Enhanced Multipoint Correlation Spectroscopy for Statistically Polarized NMR
Tobias Spohn, Nicolas Staudenmaier, Philipp J. Vetter +6 more·Mar 24, 2025
Nuclear magnetic resonance spectroscopy with solid-state spin sensors is a promising pathway for the detection of nuclear spins at the micro- and nanoscale. Although many nanoscale experiments rely on a single sensor spin for the detection of the sig...
Public-Key Quantum Money and Fast Real Transforms
Jake Doliskani, Morteza Mirzaei, Ali Mousavi·Mar 24, 2025
We propose a public-key quantum money scheme based on group actions and the Hartley transform. Our scheme adapts the quantum money scheme of Zhandry (2024), replacing the Fourier transform with the Hartley transform. This substitution ensures the ban...
Characterization of a quantum bus between two driven qubits
Alberto Hijano, Henri Lyyra, Juha T. Muhonen +1 more·Mar 24, 2025
We investigate the use of driven qubits coupled to a harmonic oscillator to implement a $\sqrt{i\mathrm{SWAP}}$-gate. By dressing the qubits through an external driving field, the qubits and the harmonic oscillator can be selectively coupled, allowin...
Optomechanical quantum bus for donor spins in silicon
Henri Lyyra, Cliona Shakespeare, Simeoni Ahopelto +6 more·Mar 24, 2025
Silicon is the foundation of current information technology, and a promising platform for future quantum information technology as silicon-based qubits exhibit some of the longest coherence times in solid-state. At the same time, silicon is the under...
