Modular fault-tolerant quantum computing on a non-CSS code
Robert Freund, Friederike Butt, César Benito +6
Modularization promises to break down the design and implementation complexity of large scale quantum processors into smaller manageable subtasks. In this approach, quantum channel…
Holographic quantum codes with trapped ions
Alex Steiner, Gerard Anglès Munné, Robert Freund +9
Holography is a central concept at the intersection of gravity, condensed matter theory, and quantum information, linking the interior bulk of a system to its boundary. A model rea…
Genuine Multipartite Entanglement between Logical Qubits via Cross-Code Lattice Surgery
Alex Steiner, Tomasz Andrzejewski, Phila Rembold +8
Universal quantum computers are expected to generate arbitrary complex quantum states of logical qubits encoded in many physical qubits. This capability hinges on a fault-tolerantl…
Nemotron 3 Ultra: Open, Efficient Mixture-of-Experts Hybrid Mamba-Transformer Model for Agentic Reasoning
NVIDIA, :, Aaron Blakeman +572
We introduce Nemotron 3 Ultra, a 550 billion total and 55 billion active parameter Mixture-of-Experts Hybrid Mamba-Attention language model. We pre-trained Nemotron 3 Ultra on 20 t…
Nemotron 3 Super: Open, Efficient Mixture-of-Experts Hybrid Mamba-Transformer Model for Agentic Reasoning
NVIDIA, :, Aakshita Chandiramani +544
We describe the pre-training, post-training, and quantization of Nemotron 3 Super, a 120 billion (active 12 billion) parameter hybrid Mamba-Attention Mixture-of-Experts model. Nemo…
Demonstration of measurement-free universal fault-tolerant quantum computation
Friederike Butt, Ivan Pogorelov, Robert Freund +4
The ability to perform quantum error correction (QEC) and robust gate operations on encoded qubits opens the door to demonstrations of quantum algorithms. Contemporary QEC schemes…
Characterizing physical and logical errors in a transversal CNOT via cycle error reconstruction
Nicholas Fazio, Robert Freund, Debankan Sannamoth +7
The development of prototype quantum information processors has progressed to a stage where small instances of logical qubit systems perform better than the best of their physical…
Solving an Industrially Relevant Quantum Chemistry Problem on Quantum Hardware
Ludwig Nützel, Alexander Gresch, Lukas Hehn +10
Quantum chemical calculations are among the most promising applications for quantum computing. Implementations of dedicated quantum algorithms on available quantum hardware were so…
Experimental measurement and a physical interpretation of quantum shadow enumerators
Daniel Miller, Kyano Levi, Lukas Postler +18
Throughout its history, the theory of quantum error correction has heavily benefited from translating classical concepts into the quantum setting. In particular, classical notions…
Dynamical quantum maps for single-qubit gates under universal non-Markovian noise
J. M. Sánchez Velázquez, A. Steiner, R. Freund +4
Noise is both ubiquitous and generally deleterious in settings where precision is required. This is especially true in the quantum technology sector where system utility typically…
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…
