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…

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…

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…
