Puncturing for Adaptive Entanglement-Assisted Stabilizer Codes
Nicolai Peder Bülow Pedersen, Jakob Kaltoft Søndergaard, Jaron Skovsted Gundersen +2
Quantum error-correcting codes are essential for reliable quantum communication. The achievable parameters can be improved by using entanglement-assisted stabilizers at the cost of…
Classical Communication Protocol based on Joint Classical-Quantum Coding
Kristian Skafte Jensen, René Bødker Christensen, Čedomir Stefanović +1
We introduce a robust quantum communication protocol that integrates classical error-control coding, entanglement distribution, and superdense coding. Classical error-correcting co…
Task Concurrency and Compatibility in Measurement-Based Quantum Networks
Jakob Kaltoft Søndergaard, René Bødker Christensen, Petar Popovski
Measurement-Based Quantum Networks (MBQNs) rely on multipartite pre-shared entanglement resources to satisfy entanglement requests. Traditional designs optimize these resources for…
Temporal Framework for Causality-Preserving Scheduling of Measurements in Quantum Networks
Jakob Kaltoft Søndergaard, René Bødker Christensen, Petar Popovski
Distributed quantum protocols rely on classical feedforward information to process measurement outcomes, but heterogeneous hardware and uncertain local timing can make the causal o…
Deflating quantum error-correcting codes
Jaron Skovsted Gundersen, Rene Bødker Christensen, Petar Popovski +1
In this work, we introduce a technique for reducing the length of a quantum stabilizer code, and we call this deflation of the code. Deflation can be seen as a generalization of th…
1Q: First-Generation Wireless Systems Integrating Classical and Quantum Communication
Petar Popovski, Čedomir Stefanović, Beatriz Soret +8
We introduce the concept of 1Q, the first wireless generation of integrated classical and quantum communication. 1Q features quantum base stations (QBSs) that support entanglement…
Satellite-Aided Entanglement Distribution for Optimized Quantum Networks
Jakob Kaltoft Søndergaard, René Bødker Christensen, Petar Popovski
Quantum internet needs to ensure timely provision of entangled qubits to be used in tasks that involve distributed quantum computing or sensing. This has been addressed by a top-do…
Puncturing Quantum Stabilizer Codes
Jaron Skovsted Gundersen, René Bødker Christensen, Markus Grassl +2
Classical coding theory contains several techniques to obtain new codes from other codes, including puncturing and shortening. For quantum codes, a form of puncturing is known, but…
Quantum Two-Way Protocol Beyond Superdense Coding: Joint Transfer of Data and Entanglement
Lorenzo Valentini, Kristian Skafte Jensen, René Bødker Christensen +2
In this article, we introduce a generalization of one-way superdense coding to two-way communication protocols for transmitting classical bits by using entangled quantum pairs. The…
Private Product Computation using Quantum Entanglement
René Bødker Christensen, Petar Popovski
In this work, we show that a pair of entangled qubits can be used to compute a product privately. More precisely, two participants with a private input from a finite field can perf…
Reliable Quantum Communications based on Asymmetry in Distillation and Coding
Lorenzo Valentini, René Bødker Christensen, Petar Popovski +1
The reliable provision of entangled qubits is an essential precondition in a variety of schemes for distributed quantum computing. This is challenged by multiple nuisances, such as…
Transforming First-Year Calculus Teaching for Engineering Students -- Blocks with Field Specific Examples, Problems, and Exams
René Bødker Christensen, Bettina Dahl, Lisbeth Fajstrup
Contribution: We demonstrate that it is feasible to include field specific problems in introductory mathematics courses to motivate engineering students. This is done in a way that…
Private Randomness Agreement and its Application in Quantum Key Distribution Networks
René Bødker Christensen, Petar Popovski
We define a variation on the well-known problem of private message transmission. This new problem called private randomness agreement (PRA) gives two participants access to a publi…
Semi-Private Computation of Data Similarity with Applications to Data Valuation and Pricing
René Bødker Christensen, Shashi Raj Pandey, Petar Popovski
Consider two data providers that want to contribute data to a certain learning model. Recent works have shown that the value of the data of one of the providers is dependent on the…

In this paper, we study the construction of quantum codes by applying Steane-enlargement to codes from the Hermitian curve. We cover Steane-enlargement of both usual one-point Herm…
On nested code pairs from the Hermitian curve
René Bødker Christensen, Olav Geil
Nested code pairs play a crucial role in the construction of ramp secret sharing schemes [Kurihara et al. 2012] and in the CSS construction of quantum codes [Ketkar et al. 2006]. T…
