Remarks on Clifford codes
Andreas Klappenecker, Martin Roetteler
Clifford codes are a class of quantum error control codes that form a natural generalization of stabilizer codes. These codes were introduced in 1996 by Knill, but only a single Cl…
Quantum Software Reusability
Andreas Klappenecker, Martin Roetteler
The design of efficient quantum circuits is an important issue in quantum computing. It is in general a formidable task to find a highly optimized quantum circuit for a given unita…
Constructions of Mutually Unbiased Bases
Andreas Klappenecker, Martin Roetteler
Two orthonormal bases B and B' of a d-dimensional complex inner-product space are called mutually unbiased if and only if |<b|b'>|^2=1/d holds for all b in B and b' in B'. The size…
Comment on "Probabilistic Quantum Memories"
T. Brun, H. Klauck, A. Nayak +2
This is a comment on two wrong Phys. Rev. Letters papers by C.A. Trugenberger. Trugenberger claimed that quantum registers could be used as exponentially large "associative" memori…
On the Monomiality of Nice Error Bases
Andreas Klappenecker, Martin Roetteler
Unitary error bases generalize the Pauli matrices to higher dimensional systems. Two basic constructions of unitary error bases are known: An algebraic construction by Knill, which…
