The limits of erasure-based postselection for quantum error mitigation
Sam J. Griffiths, Jamie Friel, Brian Vlastakis
In both classical and quantum error correction, heralded erasures are known to be easier to tolerate than unheralded general stochastic errors. Whilst an established benefit of los…
3D Integrated Embedded Filters for Superconducting Quantum Circuits
Waqas Ahmad, Gioele Consani, Mohammad Tasnimul Haque +2
Microwave filtering for superconducting qubits is a key element of quantum computing technology, enabling high coherence and fast state detection. This work presents the design and…
Developments in superconducting erasure qubits for hardware-efficient quantum error correction
Maria Violaris, Luciana Henaut, James Wills +3
Quantum computers are inherently noisy, and a crucial challenge for achieving large-scale, fault-tolerant quantum computing is to implement quantum error correction. A promising di…
Error-detected coherence metrology of a dual-rail encoded fixed-frequency multimode superconducting qubit
James Wills, Mohammad Tasnimul Haque, Brian Vlastakis
Amplitude damping is a dominant source of error in high performance quantum processors. A promising approach in quantum error correction is erasure error conversion, where errors a…
