Exploiting Quantum Teleportation in Quantum Circuit Mapping

Stefan Hillmich, Alwin Zulehner, Robert Wille

Quantum computers are constantly growing in their number of qubits, but continue to suffer from restrictions such as the limited pairs of qubits that may interact with each other.…

One Additional Qubit is Enough: Encoded Embeddings for Boolean Components in Quantum Circuits

Alwin Zulehner, Philipp Niemann, Rolf Drechsler +1

Research on quantum computing has recently gained significant momentum since first physical devices became available. Many quantum algorithms make use of so-called oracles that imp…

An Efficient Methodology for Mapping Quantum Circuits to the IBM QX Architectures

Alwin Zulehner, Alexandru Paler, Robert Wille

In the past years, quantum computers more and more have evolved from an academic idea to an upcoming reality. IBM's project IBM Q can be seen as evidence of this progress. Launched…

On the Difficulty of Inserting Trojans in Reversible Computing Architectures

Xiaotong Cui, Samah Saeed, Alwin Zulehner +4

Fabrication-less design houses outsource their designs to 3rd party foundries to lower fabrication cost. However, this creates opportunities for a rogue in the foundry to introduce…

Towards Reverse Engineering Reversible Logic

Samah Mohamed Saeed, Xiaotong Cui, Robert Wille +4

Reversible logic has two main properties. First, the number of inputs is equal to the number of outputs. Second, it implements a one-to-one mapping; i.e., one can reconstruct the i…
