Towards experimental classical verification of quantum computation
Roman Stricker, Jose Carrasco, Martin Ringbauer +8
With today's quantum processors venturing into regimes beyond the capabilities of classical devices [1-3], we face the challenge to verify that these devices perform as intended, e…
A compact ion-trap quantum computing demonstrator
Ivan Pogorelov, Thomas Feldker, Christian D. Marciniak +13
Quantum information processing is steadily progressing from a purely academic discipline towards applications throughout science and industry. Transitioning from lab-based, proof-o…
Scalable and Parallel Tweezer Gates for Quantum Computing with Long Ion Strings
Tobias Olsacher, Lukas Postler, Philipp Schindler +3
Trapped-ion quantum computers have demonstrated high-performance gate operations in registers of about ten qubits. However, scaling up and parallelizing quantum computations with l…
Entangling logical qubits with lattice surgery
Alexander Erhard, Hendrik Poulsen Nautrup, Michael Meth +8
Future quantum computers will require quantum error correction for faithful operation. The correction capabilities come with an overhead for performing fault-tolerant logical opera…
Characterizing large-scale quantum computers via cycle benchmarking
Alexander Erhard, Joel James Wallman, Lukas Postler +7
Quantum computers promise to solve certain problems more efficiently than their digital counterparts. A major challenge towards practically useful quantum computing is characterizi…
Experimental quantification of spatial correlations in quantum dynamics
Lukas Postler, Ángel Rivas, Philipp Schindler +6
Correlations between different partitions of quantum systems play a central role in a variety of many-body quantum systems, and they have been studied exhaustively in experimental…
