Multiqubit Rydberg Gates for Quantum Error Correction
David F. Locher, Josias Old, Katharina Brechtelsbauer +4
Multiqubit gates that involve three or more qubits are usually thought to be of little significance for fault-tolerant quantum error correction because single gate faults can lead…
Analog-Digital Quantum Computing with Quantum Annealing Processors
Rahul Deshpande, Majid Kheirkhah, Chris Rich +12
Quantum annealing processors typically control qubits in unison, attenuating quantum fluctuations uniformly until the applied system Hamiltonian is diagonal in the computational ba…
The stripe state at 1/8 Ba doping hosts optimal superconductivity in La-214 cuprates under low in-plane stress
V. Sazgari, S. S. Islam, M. Lamotte +20
The cuprate system LaBaCuO (LBCO) exhibits a pronounced sensitivity to in-plane uniaxial stress, particularly near the 1/8 doping anomaly, where stripe order st…
Decoding 3D color codes with boundaries
Friederike Butt, Lars Esser, Markus Müller
Practical large-scale quantum computation requires both efficient error correction and robust implementation of logical operations. Three-dimensional (3D) color codes are a promisi…
Strong electron-electron interactions in a dilute weakly-localized metal near a metal-to-insulator transition
Nicolò D'Anna, Jamie Bragg, Aidan G. McConnell +12
Because it is easily switched from insulator to metal either via chemical doping or electrical gating, silicon is at the core of modern information technology and remains a candida…
Measurement-free quantum error correction optimized for biased noise
Katharina Brechtelsbauer, Friederike Butt, David F. Locher +4
In this paper, we derive optimized measurement-free protocols for quantum error correction and the implementation of a universal gate set optimized for an error model that is noise…
