LUCI on IBM Hardware: Error Suppression with Almost Half Syndrome Density

Younghun Kim, Spiro Gicev, Martin Sevior +1

Long-lived logical qubits are essential for fault-tolerant quantum computation. However, the practical performance of traditional error correction protocols relies on performing sp…

Crosstalk In Contemporary Quantum Devices

Spiro Gicev, Ben Harper, Haiyue Kang +2

Crosstalk noise derives from phenomena in quantum devices which inhibit individual addressability or cause unintended interactions among qubits. It is widely considered one of the…

Non-Clifford Crosstalk Noise in Surface Codes Using Hybrid Stabilizer-Tensor Network Methods

Ben Harper, Azar C. Nakhl, Martin Sevior +1

Scalable realisation of quantum computing is reliant on the development of fault tolerant devices. Analysis of quantum error correction protocols typically considers incoherent noi…

Feature-level analysis and adversarial transfer in rotationally equivariant quantum machine learning

Maureen Krumtünger, Martin Sevior, Muhammad Usman

Group-equivariant quantum models are designed to exploit symmetry and can improve trainability, but it remains unclear how symmetry constraints shape their adversarial robustness.…
