Complementary 3D color codes for transversal quantum logic
Friederike Butt, Luis Colmenarez, Erik Weilandt +3
Transversal logical gates provide a direct route to fault-tolerant quantum computation, but the Eastin-Knill theorem forbids a universal transversal gate set within a single quantu…
Computational regimes in matrix-product-state-based quantum trajectory simulations
Aaron Sander, Simon Cichy, Martin Eigel +4
Efficient simulation of open quantum systems is central to modeling noisy quantum hardware and many-body dynamics. In trajectory-based tensor network methods, cost is often associa…
Synthesis and Optimization of Encoding Circuits for Fault-Tolerant Quantum Computation
Tom Peham, Matthew Steinberg, Robert Wille +1
Preparing arbitrary logical states is a central primitive for universal fault-tolerant quantum computation and the cost of encoded-state preparation contributes directly to the ove…
Synthesis of Fault-tolerant State Preparation Circuits using Steane-type Error Detection
Erik Weilandt, Tom Peham, Robert Wille
Fault-tolerant state preparation is essential for reliable quantum error correction, particularly in Steane-type error correction, which relies on robust ancilla states for syndrom…
Optimizing Fault-tolerant Cat State Preparation
Tom Peham, Erik Weilandt, Robert Wille
Cat states are an important resource for fault-tolerant quantum computing, where they serve as building blocks for a variety of fault-tolerant primitives. Consequently, the ability…
Minimizing the Number of Code Switching Operations in Fault-Tolerant Quantum Circuits
Erik Weilandt, Tom Peham, Robert Wille
Fault-tolerant quantum computers rely on Quantum Error-Correcting Codes (QECCs) to protect information from noise. However, no single error-correcting code supports a fully transve…
