Synthesis and Optimization of Encoding Circuits for Fault-Tolerant Quantum Computation
Tom Peham, Matthew Steinberg, Robert Wille +1
Preparing arbitrary logical states is a central primitive for universal fault-tolerant quantum computation and the cost of encoded-state preparation contributes directly to the ove…
Addressable fault-tolerant universal quantum gate operations for high-rate lift-connected surface codes
Josias Old, Juval Bechar, Markus Müller +1
Quantum low-density parity check (qLDPC) codes are among the leading candidates to realize error-corrected quantum memories with low qubit overhead. Potentially high encoding rates…
Quantum Internet in a Nutshell -- Advancing Quantum Communication with Ion Traps
Janine Hilder, Sascha Heußen, Anke Ginter +5
Quantum Internet in a Nutshell (QI-Nutshell) connects the fields of quantum communication and quantum computing by emulating quantum communication protocols on currently available…
Magic state distillation without measurements and post-selection
Sascha Heußen
Magic state distillation (MSD) is a quantum algorithm that enables performing logical non-Clifford gates with in principle arbitrarily low noise level. It is herein typically assum…
Efficient fault-tolerant code switching via one-way transversal CNOT gates
Sascha Heußen, Janine Hilder
Code switching is an established technique that facilitates a universal set of FT quantum gate operations by combining two QEC codes with complementary sets of gates, which each by…
Demonstration of fault-tolerant Steane quantum error correction
Lukas Postler, Friederike Butt, Ivan Pogorelov +7
Encoding information redundantly using quantum error-correcting (QEC) codes allows one to overcome the inherent sensitivity to noise in quantum computers to ultimately achieve larg…
Dynamical subset sampling of quantum error correcting protocols
Sascha Heußen, Don Winter, Manuel Rispler +1
Quantum error correcting (QEC) stabilizer codes enable protection of quantum information against errors during storage and processing. Simulation of noisy QEC codes is used to iden…
Measurement-free fault-tolerant quantum error correction in near-term devices
Sascha Heußen, David F. Locher, Markus Müller
Logical qubits can be protected from decoherence by performing QEC cycles repeatedly. Algorithms for fault-tolerant QEC must be compiled to the specific hardware platform under con…
Fault-Tolerant Code Switching Protocols for Near-Term Quantum Processors
Friederike Butt, Sascha Heußen, Manuel Rispler +1
Topological color codes are widely acknowledged as promising candidates for fault-tolerant quantum computing. Neither a two-dimensional nor a three-dimensional topology, however, c…
Strategies for practical advantage of fault-tolerant circuit design in noisy trapped-ion quantum computers
Sascha Heußen, Lukas Postler, Manuel Rispler +5
Fault-tolerant quantum error correction provides a strategy to protect information processed by a quantum computer against noise which would otherwise corrupt the data. A fault-tol…
Extracting many body localization lengths with an imaginary vector potential
Christopher David White, Sascha Heußen, Gil Refael
One challenge of studying the many-body localization transition is defining the length scale that diverges upon the transition to the ergodic phase. In this manuscript we explore t…
