Autoregressive Projective Quantum Monte Carlo: From a Hermitian to a Non-Hermitian Perspective
Lavoisier Wah, Remmy Zen, Flore K. Kunst
Accurately determining the ground-state properties of quantum many-body systems remains a central challenge. In this work, we introduce an autoregressive projective quantum Monte C…
Unitary fault-tolerant encoding of Pauli states in surface codes
Luis Colmenarez, Remmy Zen, Jan Olle +2
In fault-tolerant quantum computation, the preparation of logical states is a ubiquitous subroutine, yet significant challenges persist even for the simplest states required. In th…
Many-Body Neural Network Wavefunction for a Non-Hermitian Ising Chain
Lavoisier Wah, Remmy Zen, Flore K. Kunst
Non-Hermitian (NH) quantum systems have emerged as a powerful framework for describing open quantum systems, non-equilibrium dynamics, and engineered quantum optical materials. How…
Reusability Report: Optimizing T-count in General Quantum Circuits with AlphaTensor-Quantum
Remmy Zen, Maximilian Nägele, Florian Marquardt
Quantum computing has the potential to solve problems that are intractable for classical computers, with possible applications in areas such as drug discovery and high-energy physi…
Non-Markovian feedback for optimized quantum error correction
Matteo Puviani, Sangkha Borah, Remmy Zen +2
Bosonic codes allow the encoding of a logical qubit in a single component device, utilizing the infinitely large Hilbert space of a harmonic oscillator. In particular, the Gottesma…
Quantum Circuit Discovery for Fault-Tolerant Logical State Preparation with Reinforcement Learning
Remmy Zen, Jan Olle, Luis Colmenarez +3
The realization of large-scale quantum computers requires not only quantum error correction (QEC) but also fault-tolerant operations to handle errors that propagate into harmful er…
