Bosonic quantum error correction with microwave cavities for quantum repeaters
S. Siddardha Chelluri, Sanchar Sharma, Frank Schmidt +2
Long-distance quantum communication necessitates the use of quantum repeaters, which typically include highly coherent quantum memories. We provide a theoretical analysis of the se…
Generalized fusions of photonic quantum states using static linear optics
Frank Schmidt, Peter van Loock
Using numerical simulations, we explore generalized fusion measurements, extending them in three key ways. We incorporate ancilla-boosting and code-boosting to optimize fusion meas…
Error-corrected quantum repeaters with GKP qudits
Frank Schmidt, Daniel Miller, Peter van Loock
The Gottesman-Kitaev-Preskill (GKP) code offers the possibility to encode higher-dimensional qudits into individual bosonic modes with, for instance, photonic excitations. Since ph…
Exact rate analysis for quantum repeaters with imperfect memories and entanglement swapping as soon as possible
Lars Kamin, Evgeny Shchukin, Frank Schmidt +1
We present an exact rate analysis for a secret key that can be shared among two parties employing a linear quantum repeater chain. One of our main motivations is to address the que…
Quantum error correction with higher Gottesman-Kitaev-Preskill codes: minimal measurements and linear optics
Frank Schmidt, Peter van Loock
We propose two schemes to obtain Gottesman-Kitaev-Preskill (GKP) error syndromes by means of linear optical operations, homodyne measurements and GKP ancillae. This includes showin…
Extending Quantum Links: Modules for Fiber- and Memory-Based Quantum Repeaters
Peter van Loock, Wolfgang Alt, Christoph Becher +9
We analyze elementary building blocks for quantum repeaters based on fiber channels and memory stations. Implementations are considered for three different physical platforms, for…
Memory-assisted long-distance phase-matching quantum key distribution
Frank Schmidt, Peter van Loock
We propose a scheme that generalizes the loss scaling properties of twin-field or phase-matching quantum key distribution (QKD) related to a channel of transmission fro…
Efficiencies of logical Bell measurements on CSS codes with static linear optics
Frank Schmidt, Peter van Loock
We show how the efficiency of a logical Bell measurement (BM) can be calculated for arbitrary CSS codes with the experimentally important constraint of using only transversal stati…
On the waiting time in quantum repeaters with probabilistic entanglement swapping
E. Shchukin, F. Schmidt, P. van Loock
The standard approach to realize a quantum repeater relies upon probabilistic but heralded entangled state manipulations and the storage of quantum states while waiting for success…
