Exponential logical-error reduction in quantum memories via optimal syndrome-measurement timing
Tobias Haug, Kishor Bharti, Leandro Aolita
Syndrome-measurements timing is usually treated as a fixed clock cycle of a quantum error-correcting code. For quantum memories, however, the intra-measurement interval is itself a…
Machine-learned syndrome post-selection for reliable quantum error correction
Tobias Haug, Askery Canabarro, Leandro Aolita
Quantum error correction can be enhanced by post-selecting out runs that are likely to produce a logical failure, but the most accurate measures for that require costly decoder-lev…
Exponential Speed-ups for Structured Goemans-Williamson relaxations via Quantum Gibbs States and Pauli Sparsity
Haomu Yuan, Daniel Stilck França, Ilia Luchnikov +3
Quadratic Unconstrained Binary Optimization (QUBO) problems are prevalent in various applications and are known to be NP-hard. The seminal work of Goemans and Williamson introduced…
Rise and fall of nonstabilizerness via random measurements
Annarita Scocco, Wai-Keong Mok, Leandro Aolita +2
We investigate the dynamics of nonstabilizerness - also known as `magic' - in monitored quantum circuits composed of random Clifford unitaries and local projective measurements. Fo…
Quantum optimization with exact geodesic transport
André J. Ferreira-Martins, Renato M. S. Farias, Giancarlo Camilo +6
We introduce an architecture for variational quantum algorithms that can be efficiently trained via parameter updates along exact geodesics on the Riemannian state manifold. This f…
Disentangling quantum autoencoder
Adithya Sireesh, Abdulla Alhajri, M. S. Kim +1
Entangled quantum states are highly sensitive to noise, which makes it difficult to transfer them over noisy quantum channels or to store them in quantum memory. Here, we propose t…
