Hardware-Efficient Ground-State Preparation using Variational Imaginary-Time Majorana Evolution
Federico Santona, Manuel G. Algaba, Aeishah Ameera Anuar +3
Compact ground-state preparation circuits are essential for early fault-tolerant quantum chemistry. We introduce Variational Imaginary-time Majorana Evolution (VIME), a classical p…
Provable and scalable quantum Gaussian processes for quantum learning
Jonas Jäger, Paolo Braccia, Pablo Bermejo +3
Despite rapid recent advances in quantum machine learning, the field is in many ways stuck. Existing approaches can exhibit serious limitations, and we still lack learning framewor…
Fermion-to-qubit encodings with arbitrary code distance
Manuel G. Algaba, Miha Papič, Inés de Vega +2
We introduce a framework which allows to systematically and arbitrarily scale the code distance of local fermion-to-qubit encodings in one and two dimensions without growing the we…
Near-Term Fermionic Simulation with Subspace Noise Tailored Quantum Error Mitigation
Miha Papič, Manuel G. Algaba, Emiliano Godinez-Ramirez +4
Quantum error mitigation (QEM) has emerged as a powerful tool for the extraction of useful quantum information from quantum devices. Here, we introduce the Subspace Noise Tailoring…
Technology and Performance Benchmarks of IQM's 20-Qubit Quantum Computer
Leonid Abdurakhimov, Janos Adam, Hasnain Ahmad +111
Quantum computing has tremendous potential to overcome some of the fundamental limitations present in classical information processing. Yet, today's technological limitations in th…
Benchmarking Digital-Analog Quantum Computation
Vicente Pina Canelles, Manuel G. Algaba, Hermanni Heimonen +6
Digital-Analog Quantum Computation (DAQC) has recently been proposed as an alternative to the standard paradigm of digital quantum computation. DAQC creates entanglement through a…
Optimal, hardware native decomposition of parameterized multi-qubit Pauli gates
P. V. Sriluckshmy, Vicente Pina-Canelles, Mario Ponce +3
We show how to efficiently decompose a parameterized multi-qubit Pauli (PMQP) gate into native parameterized two-qubit Pauli (P2QP) gates minimizing both the circuit depth and the…
Low-depth simulations of fermionic systems on square-grid quantum hardware
Manuel G. Algaba, P. V. Sriluckshmy, Martin Leib +1
We present a general strategy for mapping fermionic systems to quantum hardware with square qubit connectivity which yields low-depth quantum circuits, counted in the number of nat…
Co-Design quantum simulation of nanoscale NMR
Manuel G. Algaba, Mario Ponce-Martinez, Carlos Munuera-Javaloy +7
Quantum computers have the potential to efficiently simulate the dynamics of nanoscale NMR systems. In this work we demonstrate that a noisy intermediate-scale quantum computer can…
