A square-root speedup for finding the smallest eigenvalue
Alex Kerzner, Vlad Gheorghiu, Michele Mosca +4
We describe a quantum algorithm for finding the smallest eigenvalue of a Hermitian matrix. This algorithm combines Quantum Phase Estimation and Quantum Amplitude Estimation to achi…
Simulating 2D lattice gauge theories on a qudit quantum computer
Michael Meth, Jan F. Haase, Jinglei Zhang +11
Particle physics underpins our understanding of the world at a fundamental level by describing the interplay of matter and forces through gauge theories. Yet, despite their unmatch…
Minimal qubit representations of Hamiltonians via conserved charges
Lane G. Gunderman, Andrew J. Jena, Luca Dellantonio
In the last years, we have been witnessing a tremendous push to demonstrate that quantum computers can solve classically intractable problems. This effort, initially focused on the…
Measurement-based infused circuits for variational quantum eigensolvers
Albie Chan, Zheng Shi, Luca Dellantonio +2
Variational quantum eigensolvers (VQEs) are successful algorithms for studying physical systems on quantum computers. Recently, they were extended to the measurement-based model of…
Enhancing Quantum Computation via Superposition of Quantum Gates
Jorge Miguel-Ramiro, Zheng Shi, Luca Dellantonio +3
Overcoming the influence of noise and imperfections in quantum devices is one of the main challenges for viable quantum applications. In this article, we present different protocol…
Superposed Quantum Error Mitigation
Jorge Miguel-Ramiro, Zheng Shi, Luca Dellantonio +3
Overcoming the influence of noise and imperfections is a major challenge in quantum computing. Here, we present an approach based on applying a desired unitary computation in super…
