Qubit Loss Inference with Stabilizer Codes without Leakage Detection Units
Shin Nishio, Takeaki Uno, Fumiyoshi Kobayashi +2
Qubit loss occurs when the physical carrier of a qubit leaves the computational system without directly revealing the event's location. Such errors are a major obstacle to fault-to…
Anticipating Decoder Side-channel Attacks in Fault-tolerant Quantum Computers
Shashvat Shukla, Dan E. Browne, Shin Nishio
As quantum computing emerges as an applied technology, there is a growing need to protect quantum computers against information security attacks. This work identifies a new class o…
Efficiently simulable quantum circuits with large entanglement, magic, and non-Gaussianity via code-compiled tensor networks
Aydin Deger, Stergios Koutsioumpas, Mark Webster +3
We introduce a family of quantum circuits that possess standard indicators of classical simulation hardness including high entanglement entropy, magic, and non-Gaussianity, yet adm…
Efficient Preparation of Graph States using the Quotient-Augmented Strong Split Tree
Nicholas Connolly, Shin Nishio, Dan E. Browne +2
Graph states are a key resource for measurement-based quantum computation and quantum networking, but state-preparation costs limit their practical use. Graph states related by loc…
High-performance syndrome extraction circuits for quantum codes
Armands Strikis, Dan E. Browne, Michael E. Beverland
We present a fast and effective framework for analysing and designing syndrome extraction circuits (SECs). Our approach is based on left--right circuits, a general SEC design that…
