A symmetry-leveraging framework for fault-tolerant ancilla preparation in quantum BCH codes yields lower spatial overhead and logical error rates than standard distillation in simulations up to 127 qubits.
Continuous coherent noise modeled via von Mises-Fisher rotations degrades logical performance in quantum error-correcting codes more than equivalent Pauli noise.
Catalytic Quantum Error Correction recovers known target states from noisy copies with F > 0.96 using only eight copies by preserving coherent modes and applying a CPMG-Clifford-swap-test pipeline, bypassing magnitude thresholds of standard QEC.
A new encoding scheme for exp(-iθP) into stabilizer codes like [[n,n-2,2]] and [[5,1,3]] achieves 4-7x lower noise than unencoded versions with at most 3% runs discarded after postselection.
Evolutionary BP+OSD achieves higher decoding performance and lower complexity than standard BP+OSD on surface and QLDPC codes, especially under low-latency constraints.
Global multiqubit Rydberg gates enable break-even measurement-free QEC and lower-shuttling Floquet codes in neutral-atom hardware.
The concatenated dual displacement code suppresses Gaussian displacement error variance by up to 50% under infinite squeezing while correcting lattice-crossing events in CV quantum error correction.
Entanglement boosting protocol prepares logical Bell pairs in rotated surface codes with orders-of-magnitude lower link-limited volume, reaching 10^{-10} logical error from 86 physical pairs at 1% error using soft decoders and postselection within one patch.
Quantum error correction encoding requires energy that scales exponentially with desired precision, varying by code and physical realization.
The paper identifies four key hurdles in the transition from NISQ to FASQ quantum computers and argues that targeting them will accelerate progress toward useful quantum advantage.
