Optimized Telecloning Circuits: Theory and Practice of Nine NISQ Clones
Elijah Pelofske, Andreas Bärtschi, Stephan Eidenbenz
Although perfect copying of an unknown quantum state is not possible, approximate cloning is possible in quantum mechanics. Quantum telecloning is a variant of approximate quantum…
Short-Depth Circuits for Dicke State Preparation
Andreas Bärtschi, Stephan Eidenbenz
We present short-depth circuits to deterministically prepare any Dicke state |Dn,k>, which is the equal-amplitude superposition of all n-qubit computational basis states with Hammi…
Quantum Telecloning on NISQ Computers
Elijah Pelofske, Andreas Bärtschi, Bryan Garcia +2
Due to the no-cloning theorem, generating perfect quantum clones of an arbitrary unknown quantum state is not possible, however approximate quantum clones can be constructed. Quant…
Numerical Evidence for Exponential Speed-up of QAOA over Unstructured Search for Approximate Constrained Optimization
John Golden, Andreas Bärtschi, Stephan Eidenbenz +1
Despite much recent work, the true promise and limitations of the Quantum Alternating Operator Ansatz (QAOA) are unclear. A critical question regarding QAOA is to what extent its p…
