Sound certification of memory-bounded quantum computers
Jan Nöller, Nikolai Miklin, Martin Kliesch +1
The rapid advancement of quantum hardware calls for the development of reliable methods to certify its correct functioning. However, existing certification tests often fall short:…
On Computational Complexity of Unitary and State Design Properties
Yoshifumi Nakata, Yuki Takeuchi, Martin Kliesch +1
We investigate unitary and state -designs from a computational complexity perspective. First, we address the problems of computing frame potentials that characterize (approximat…
Shot-noise reduction for lattice Hamiltonians
Timo Eckstein, Refik Mansuroglu, Stefan Wolf +4
Efficiently estimating energy expectation values of quantum lattice systems on quantum computers is a crucial subroutine for various quantum algorithms, which can lead to significa…
General, efficient, and robust Hamiltonian engineering
Pascal Baßler, Markus Heinrich, Martin Kliesch
Implementing the time evolution under a desired target Hamiltonian is critical for various applications in quantum science. Due to the exponential increase in the number of paramet…
Bosonic randomized benchmarking with passive transformations
Mirko Arienzo, Dmitry Grinko, Martin Kliesch +1
Randomized benchmarking (RB) is the most commonly employed protocol for the characterization of unitary operations in quantum circuits due to its reasonable experimental requiremen…
Classical certification of quantum gates under the dimension assumption
Jan Nöller, Nikolai Miklin, Martin Kliesch +1
The rapid advancement of quantum hardware necessitates the development of reliable methods to certify its correct functioning. However, existing certification tests fall short, as…
