Weakly Fault-Tolerant Computation in a Quantum Error-Detecting Code
Christopher Gerhard, Todd A. Brun·Aug 27, 2024
Many current quantum error-correcting codes that achieve full fault tolerance suffer from having low ratios of logical to physical qubits and significant overhead. This makes them difficult to implement on current noisy intermediate-scale quantum (NI...
Practical Quantum Advantage on Partially Fault-Tolerant Quantum Computer
Riki Toshio, Yutaro Akahoshi, J. Fujisaki +3 more·Aug 27, 2024
Achieving quantum speedups in practical tasks remains challenging for current noisy intermediate-scale quantum (NISQ) devices. These devices always encounter significant obstacles such as inevitable physical errors and the limited scalability of curr...
Compilation of Trotter-Based Time Evolution for Partially Fault-Tolerant Quantum Computing Architecture
Yutaro Akahoshi, Riki Toshio, J. Fujisaki +3 more·Aug 27, 2024
Achieving practical quantum speedup with limited resources is a crucial challenge in both academic and industrial communities. To address this, a partially fault-tolerant quantum computing architecture called ``space-time efficient analog rotation qu...
Comprehensive explanation of ZZ coupling in superconducting qubits
Simon Pettersson Fors, Jorge Fern'andez-Pend'as, A. F. Kockum·Aug 27, 2024
A major challenge for scaling up superconducting quantum computers is unwanted couplings between qubits, which lead to always-on ZZ couplings that impact gate fidelities by shifting energy levels conditional on qubit states. To tackle this challenge,...
Automated Synthesis of Quantum Algorithms via Classical Numerical Techniques
Yuxin Huang, Benjamin E. Grossman‐Ponemon, David Hyde·Aug 27, 2024
We apply numerical optimization and linear algebra algorithms for classical computers to the problem of automatically synthesizing algorithms for quantum computers. Using our framework, we apply several common techniques from these classical domains ...

A. Belov, A. Morozov·Aug 26, 2024
Chern–Simons theory in application to the quantum computing is actively developing at the present. However, most discussed are the questions of using materials with known parameters and building corresponding quantum gates and algorithms. In this pap...
Recipe for local simulation of strongly correlated fermionic matter on quantum computers: The two-dimensional Fermi-Hubbard model
Arash Jafarizadeh, F. Pollmann, A. Gammon-Smith·Aug 26, 2024
The simulation of quantum many-body systems, relevant for quantum chemistry and condensed matter physics, is one of the most promising applications of near-term quantum computers before fault-tolerance. However, since the vast majority of quantum com...
Non-iterative disentangled unitary coupled-cluster based on lie-algebraic structure
Mohammad Haidar, Olivier Adjoua, Siwar Badreddine +2 more·Aug 26, 2024
Due to their non-iterative nature, fixed unitary coupled cluster (UCC) ansätze are attractive for performing quantum chemistry variational quantum eigensolver (VQE) computations as they avoid pre-circuit measurements on a quantum computer. However, a...

Max Cykiert, E. Ginossar·Aug 24, 2024
In the era of Noisy Intermediate-Scale Quantum computing as well as in error correcting circuits, physical qubits coherence time and high fidelity gates are essential to the functioning of quantum computers. In this paper, we demonstrate theoreticall...
